Time to highlight a few past posts for anyone who may have stumbled upon this blog recently.<br />
<br />
If
my ever-growing list of things to post about is any indication, Thought Offerings will not be in hibernation forever.... that said, I don't know
how soon real posting activity will resume. On my list are specific
posts about the usual macroeconomic blog fare: interest rate policy
foundations and effects, economic growth dynamics, job guarantee versus
job or income guarantee, confusion about flows versus changes in flows,
dynamics of inflation, debt and demographics, money supply dynamics, and more.<br />

If you've been subscribed to this blog via Google Reader and
haven't yet chosen a new RSS feed reader (with Google Reader going offline very soon), I suggest giving <a href="http://www.newsblur.com/">NewsBlur</a> a
try. It's a little buggy still but seems very promising, with both
mobile app and full web versions. Alternate suggestions are very welcome though
-- I only recently started looking at current options.</div>
<br />
For newcomers, here are some past posts I recommend:<br />
<ul>
<li>I have seen a handful of bloggers refer to the possibility that interest rate policy might work primarily through the housing channel, but I've never seen anyone detail <i>how</i> that might be true. Here are my previous thoughts on the mechanics (but with the bottom line that monetary policy is still <i>mostly </i>a placebo): <a href="http://www.thoughtofferings.com/2012/06/cutting-interest-rates-to-boost-economy.html">Cutting Interest Rates to Boost the Economy: A Fallacy of Composition just like the False Notion of Cutting Wages to Create Jobs?</a></li>
<li>Some thoughts on a specific <a href="http://www.thoughtofferings.com/2012/05/job-guarantee-is-description-of.html">MMT-style job guarantee program</a> that could be highly beneficial to sustainable economic growth, and <i>possibly</i> more politically palatable than a more open-ended JG program: <a href="http://www.thoughtofferings.com/2012/01/ultimate-job-guarantee-implementation.html">The Ultimate Job Guarantee Implementation: Can we Achieve Zero Wasted Labor AND Zero Material Waste Simultaneously?!?</a> and <a href="http://www.thoughtofferings.com/2012/05/zero-waste-jobs-program-revisited-can.html">The Zero Waste Jobs Program Revisited: Can We Recycle Over 80% of Trash Instead of Under 35% While Ending Involuntary Unemployment?</a></li>
<li>The Japan stagnation thing is a myth that even otherwise astute MMT bloggers have seemed to fall for (though I've been out of the loop more recently)... Yes, Japan's population growth has stagnated, but real GDP growth per capita shows things in a different light if looked at on a long enough timeline. <a href="http://www.thoughtofferings.com/2011/04/real-gdp-per-capita-and-myths-about.html">Real GDP Per Capita and Myths about Japan's Stagnation</a> and <a href="http://www.thoughtofferings.com/2012/01/myths-about-japans-stagnation-revisited.html">Myths about Japan's Stagnation Revisited.</a></li>
</ul>
Those are a few of the ones that I'm most happy with and that I think remain most relevant despite being old. I've also done a series of 3-4 posts on QE and money supply endogeneity that I will try to revisit some time in the light of later data, though I'm not sure at this point whether the posts were on the mark, and I've since seen references to Kaldor and others on similar topics and have not fully explored them.<br />

<br />
For regular readers of technical Post-Keynesian and/or MMT material, it likely won't be anything new -- at this point it's mostly an intro to the relationship between bank reserves and broad money supply that shows why the mainstream "money multiplier" view is mistaken.<br />
<br />
If you're interested in taking a look despite the incomplete state of it, I'll send you via the EconViz blog post since there is a mini poll up over there: <a href="http://econviz.org/blog/2012/09/new-tutorial-why-central-banks-dont-control-the-money-supply/">New Tutorial: Why Central Banks Don’t Control the Money Supply…</a>hblhttp://www.blogger.com/profile/03192933210484147113noreply@blogger.com2tag:blogger.com,1999:blog-7861688742346636904.post-33463810140635427912012-06-06T17:46:00.004-04:002012-06-06T22:32:19.280-04:00Cutting Interest Rates to Boost the Economy: A Fallacy of Composition just like the False Notion of Cutting Wages to Create Jobs?Does monetary policy work? Can the central bank meaningfully impact the economy and employment by altering interest rates? Or, as <a href="http://moslereconomics.com/">Warren Mosler</a> sometimes suggests, are central bankers like the kid in the back seat turning the plastic steering wheel and thinking they are controlling the car?<br /><br />Either way, most <span style="font-style: italic;">mainstream</span> economists are firm believers in the power of monetary policy as a tool for steering the economy.<br /><br />Let's first consider a different example of economy-wide price changes. Here is <a href="http://krugman.blogs.nytimes.com/2009/12/16/would-cutting-the-minimum-wage-raise-employment/">Paul Krugman</a> (a prominent mainstream economist) on the fallacy of composition regarding wage cuts leading to greater overall employment <span style="font-style: italic;">(color emphasis mine)</span>:<br /><blockquote>"So let me repeat a point I made a number of times back when the usual suspects were declaring that FDR prolonged the Depression by raising wages: the belief that lower <span style="color: rgb(0, 153, 0);">wages</span> would raise overall employment rests on a fallacy of composition. In reality, reducing <span style="color: rgb(0, 153, 0);">wages</span> would at best do nothing for employment; more likely it would actually be contractionary.<br /><br />"Here’s how the fallacy works: if some subset of the work force accepts lower wages, it can gain jobs. If workers in the widget industry take a pay cut, this will lead to lower prices of widgets relative to other things, so people will buy more widgets, hence more employment.<br /><br />"But if everyone takes a pay cut, that logic no longer applies. The only way a general cut in <span style="color: rgb(0, 153, 0);">wages</span> can increase employment is if it leads people to buy more across the board. And why should it do that?"</blockquote><span style="font-style: italic;">(To see an illustration of why wage cuts won't create jobs overall, try the EconViz pages on how</span><a style="font-style: italic;" href="http://econviz.org/how-the-economy-works-visual-tutorial/#spending"> spending equals income</a><span style="font-style: italic;"> at the macroeconomic level and about </span><a style="font-style: italic;" href="http://econviz.org/how-the-economy-works-visual-tutorial/#inflation">price level changes aka inflation</a><span style="font-style: italic;">.)</span><br /><br />Just for fun, let's change the word "wages" to "interest rates" for two sentences from the quote above, and inject one example ("houses"):<br /><blockquote>"...the belief that lower <span style="color: rgb(0, 153, 0);">interest rates</span> would raise overall employment rests on a fallacy of composition. In reality, reducing <span style="color: rgb(0, 153, 0);">interest rates</span> would at best do nothing for employment; more likely it would actually be contractionary... The only way a general cut in <span style="color: rgb(0, 153, 0);">interest rates</span> can increase employment is if it leads people to buy more <span style="color: rgb(0, 153, 0);">[e.g., houses]</span> across the board. And why should it do that?"</blockquote>Word games do not a proof make, but let's work through how this fallacy of composition might apply in the case of interest rates as well as wages.<br /><br />So, what is the transmission mechanism by which interest rate changes supposedly help steer the economy? Paul Krugman <a href="http://krugman.blogs.nytimes.com/2011/04/04/the-transmission-mechanism-for-quantitative-easing-wonkish/">again</a> <span style="font-style: italic;">(emphasis mine)</span>:<br /><blockquote>"Back in the old days, when dinosaurs roamed the earth and students still learned Keynesian economics, we used to hear a lot about the monetary “transmission mechanism” — how the Fed actually got traction on the real economy. Both the phrase and the subject have gone out of fashion — but it’s still an important issue, and arguably now more than ever.<br /><br />"Now, what you learned back then was that<span style="font-weight: bold;"> the transmission mechanism worked largely through housing</span>. Why? Because long-lived investments are very sensitive to interest rates, short-lived investments not so much. <span style="font-weight: bold;">If a company is thinking about equipping its employees with smartphones that will be antiques in three years, the interest rate isn’t going to have much bearing on its decision; and a lot of business investment is like that, if not quite that extreme.</span> But houses last a long time and don’t become obsolete (the same is true to some extent for business structures, but in a more limited form). So Fed policy, by moving interest rates, normally exerts its effect mainly through housing."</blockquote>So Krugman suggests that for the most part, <span style="font-weight: bold;">corporate investment is not part of the transmission mechanism and that they key driver is housing</span>. Here's Krugman <a href="http://krugman.blogs.nytimes.com/2012/01/27/postmodern-business-cycles/">again</a> <span style="font-style: italic;">(emphasis mine)</span>:<br /><blockquote>"As I said then, there’s a definite change in the character of recessions after the mid-1980s. Before then, recessions were basically brought on by the Fed, which raised interest rates sharply to curb inflation, causing a slump in housing. When the Fed decided that we had suffered enough, it let rates fall again, and there was a surge from pent-up housing demand. Morning in America!<br /><br />"Since then, however, inflation has been well under control, and booms have died of old age — or more precisely, they have died because of overbuilding and an excessive level of debt. <span style="font-weight: bold;">The Fed is then in the position of trying to goose housing (which is the principal channel for monetary policy) even though housing may already be overbuilt</span> (which was the point I was making, sarcastically, when I said long ago that the Fed has to create a housing bubble), and it is cutting rates from an initial level which isn’t that high. So the odds of running up against the zero lower bound are high, and recovery can be a long time in coming."</blockquote>The quote above further emphasizes the housing channel, but acknowledges that after a housing bubble that has ended with excess inventory, the the Fed's policy efficacy may be reduced.<br /><br />We'll revisit the housing channel in more detail soon, but first, what about the sometimes cited expectations channel? Here is blogger Winterspeak on <a href="http://www.winterspeak.com/2010/12/why-inflations-expectation-model-is.html">Why the inflations expectation model is nonsense</a>:<br /><blockquote>"Primarily, people save for things:<br />1. They cannot afford currently (and don't want to buy on credit)<br />2. Unexpected emergencies<br />3. Old age<br />4. Bequests for their kids<br /><br />"2-4 cannot be moved forward and so are not inter temporal decisions the way the models treat them. Therefore, if savings are threatened, people will substitute into other stores of value such as fx or gold. They will not move consumption forward, as they cannot. This is not about consumption."</blockquote>Additionally, if it turns out that there is <span style="font-style: italic;">no transmission mechanism</span> from interest rates (the main policy lever of a central bank) to economic growth (and possible resultant inflation), then why should people alter their behavior based on the proclamation of Fed officials that they might "target" higher inflation? Target <span style="font-style: italic;">how</span>?!?<br /><br />Back to housing. We'll discuss a starting scenario (Scenario A) and four possible outcomes of monetary policy changes (Scenarios B, C, D, and E).<br /><br /><span style="font-weight: bold;">Scenario A (Starting Scenario) for Housing</span><br /><br />Let's look closely at whether the housing channel EVER works (i.e., even when there has not been a recent housing bubble). Consider the diagram below of the relative quantities of different measures of housing: ownership (owned outright versus with a mortgage), vacancies (vacant versus occupied), and occupancy type (whether occupied homes are lived in by owners or renters). The diagram's format and example numbers were in part inspired by a graph featured at <a href="http://www.calculatedriskblog.com/2012/05/graph-us-housing-market-summary.html">Calculated Risk</a>, though I've chosen a slightly different way of showing things.<br /><br /><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh6FAgnO1jr90YJT-MRvp8iG45PZ9lUubAzJ0UZgfY-HRC-Xns4eEzgrTSKfc-3ZA_BBzFL5MVU1q_J8_U4OAGe9AZOIqgfPfUMaNBKC1LzRDZ7o90PsZZJiAnoq5VCAxkj3CuZ711Mru6m/s1600/InterestRatesHousing-ScenarioA.png"><img style="cursor:pointer; cursor:hand;width: 400px; height: 218px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh6FAgnO1jr90YJT-MRvp8iG45PZ9lUubAzJ0UZgfY-HRC-Xns4eEzgrTSKfc-3ZA_BBzFL5MVU1q_J8_U4OAGe9AZOIqgfPfUMaNBKC1LzRDZ7o90PsZZJiAnoq5VCAxkj3CuZ711Mru6m/s400/InterestRatesHousing-ScenarioA.png" alt="" id="BLOGGER_PHOTO_ID_5750294806387890258" border="0" /></a><br /><br /><span style="font-weight: bold;">Scenario B for Housing</span><br /><br />Now for scenario B, let's assume the central bank lowers interest rates in an attempt to stimulate the economy. The conventional wisdom is that lower interest rates motivate more people to borrow to buy houses. That's represented by the red arrow showing the size of the "Owner Has Mortgage" block expanding in the diagram below:<br /><br /><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhGBn73MqALlu1UQKHhfnrlsmbqJ1Is6x39-dThwJHEf5CM39p6hjZXXWrWKGc3D3siREp50mi545msb1HwlDKJorHRKM2p6LBp_LKuAjCs8KDo2yRzPMyL2JYOQuaBMw6QvNEjXTtaW3mu/s1600/InterestRatesHousing-ScenarioB.png"><img style="cursor:pointer; cursor:hand;width: 400px; height: 281px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhGBn73MqALlu1UQKHhfnrlsmbqJ1Is6x39-dThwJHEf5CM39p6hjZXXWrWKGc3D3siREp50mi545msb1HwlDKJorHRKM2p6LBp_LKuAjCs8KDo2yRzPMyL2JYOQuaBMw6QvNEjXTtaW3mu/s400/InterestRatesHousing-ScenarioB.png" alt="" id="BLOGGER_PHOTO_ID_5750294881371957698" border="0" /></a><br /><br />How do the other blocks react so that the first three columns always remain the same total height? In step 2 of this scenario, more new houses are built to keep up with this demand. But as step 3 shows us, the result is more vacant homes, since the central bank wasn't able to manufacture more people at the same time as it lowered interest rates!<br /><br />What is the carrying cost of vacant homes? My cursory research suggests that in the US, property taxes range from 0.1% to 2% of a home's value (usually around 1%) and that annual maintenance costs fall in the range of 1%-4% of a home's value. Even if we very conservatively assume the average carrying cost of vacant housing were only 2% of the home's value per year, who exactly is supposed to shoulder that cost burden without putting their "excess" (not lived in or able to be rented) housing inventory on the market, thus competing with new home sales, and counteracting the effect shown in step 2?<br /><br />Does this dynamic rely on highly inefficient markets, "irrrational" individuals, or sufficient time lags to induce a temporary spurt of economic growth? It seems plausible (to some degree) but not entirely convincing.<br /><br />There is a situation in which it seems reasonable to assuming a growing supply of vacant homes -- during a housing bubble. The reason is that if home values are appreciating fast enough, home owners will overlook the annual carrying cost of the homes and assume that they are a profitable "investment" due to the unrealized capital gains. But housing bubbles are not the norm!<br /><br />Is the inventory held tax free by home builders? Probably not -- on aggregate nationwide, they are unlikely to build excess homes if there aren't sufficient buyers in the pipeline.<br /><br /><span style="font-weight: bold;">Scenario C for Housing</span><br /><br />Here's an alternate scenario to consider. In Scenario C (diagram below), steps 1 and 2 are the same as Scenario B (lower rates lead to more homes bought with mortgages), but in step 3 people are motivated by the lower mortgage rates to move out of shared multi-person housing and into newly purchased homes, reducing the average occupancy rate. So this is a scenario in which monetary policy <span style="font-style: italic;">could</span> credibly have the intended effect on economic growth via the housing channel as more homes are built, creating more jobs and higher GDP. But how large is this dynamic? How many households have gainfully employed individuals (who would qualify for a mortgage) just waiting to move out of their friend's house or parents' basement when rates get low enough?<br /><br /><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjnkLutJT24EfrpvOb_IQYOohk60W2t4fv_2RNgM-yDyr2LUKexK-F25tWVIcPdN7oPka5NyppwvIby0dGcmYrHG8LS6nYV2OssbaeVcC_lGNpja5NkOxibxQ58S_P5IUVv3yCAaFVYyxJw/s1600/InterestRatesHousing-ScenarioC.png"><img style="cursor:pointer; cursor:hand;width: 400px; height: 260px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjnkLutJT24EfrpvOb_IQYOohk60W2t4fv_2RNgM-yDyr2LUKexK-F25tWVIcPdN7oPka5NyppwvIby0dGcmYrHG8LS6nYV2OssbaeVcC_lGNpja5NkOxibxQ58S_P5IUVv3yCAaFVYyxJw/s400/InterestRatesHousing-ScenarioC.png" alt="" id="BLOGGER_PHOTO_ID_5750294961287878434" border="0" /></a><br /><br /><span style="font-weight: bold;">Scenario D for Housing</span><br /><br />Let's consider a third scenario. After the central bank lowers interest rates, more people buy homes by taking out mortgages. But on average, owners who had no mortgage are net sellers (perhaps there is a relative portfolio shift by this demographic, on average, to other choices of assets). So in Scenario D, all that occurs is a shift in overall ownership mix between owners with mortgages and those without! There is no impact on economic growth or job creation!<br /><br /><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgyXhY4v1JYDwp9NNQjMIH1XQTmccBD9qnImahZhnxx8rgm-am1f7IK5ErckcouDkBKYpFiig6ObXG9apJ_uC-35j-_ZsbzBF3WSJUSNh_QjzpLg0FyW15IIhWC3hoFXSyGNXuMxDN0kONg/s1600/InterestRatesHousing-ScenarioD.png"><img style="cursor:pointer; cursor:hand;width: 400px; height: 274px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgyXhY4v1JYDwp9NNQjMIH1XQTmccBD9qnImahZhnxx8rgm-am1f7IK5ErckcouDkBKYpFiig6ObXG9apJ_uC-35j-_ZsbzBF3WSJUSNh_QjzpLg0FyW15IIhWC3hoFXSyGNXuMxDN0kONg/s400/InterestRatesHousing-ScenarioD.png" alt="" id="BLOGGER_PHOTO_ID_5750295014653905650" border="0" /></a><br /><br /><span style="font-weight: bold;">Scenario E for Housing</span><br /><br />Lastly, let's consider the possibility that lower interest rates have the effect of raising housing prices above what they otherwise would have been, since buyers obtaining mortgages would potentially qualify for a larger loan amount, allowing them to bid more for houses. To the extent that this occurs, lower interest rates wouldn't have as large an effect in lowering housing affordability (monthly payment) as the interest rate changes alone would suggest, and this scenario's diagram would look just like the original -- Scenario A... unchanged, with no meaningful effect on GDP.<br /><br />In reality interest rate changes almost certainly aren't completely offset by housing price changes in this way, but there could be a partial effect along these lines!<br /><br /><span style="font-weight: bold;">Other Economic Impacts of Interest Rate Changes</span><br /><br />Changes in interest rates might have impacts on other prices in the economy. For example, asset prices could change, driving changes in behavior due to portfolio and wealth effects. Savings rates might change -- for example when rates are lowered people need to save more to achieve savings goals such as for retirement, thus hurting GDP growth. Since the government is a net payer of interest (on government debt), lower rates reduce income payments to the private sector, also hurting growth. But interest rates paid between borrowers and lenders (both in the private sector) can also be impacted, causing distributional shifts. The point is that interest rate changes <span style="font-style: italic;">can</span> have effects, but monetary policy is what MMT economists call a <span style="font-style: italic;">blunt instrument</span>, and the overall effects are very difficult to determine.<br /><br /><span style="font-weight: bold;">Conclusion</span><br /><br />Which scenario, B, C, D, or E is the most likely outcome of changes in interest rates with respect to the housing market? Are there other reasonable scenarios not covered in this post? Why do mainstream economists such as Paul Krugman recognize the fallacy of composition when it comes to whether lower wages will create jobs, but believe that lower interest rates have so much power over economic growth?<br /><br />I would guess that in reality a mix of all four scenarios (B, C, D, & E) occurs. Given the limited macroeconomic impacts of each scenario, the bottom line is that the power of interest rates to affect economic growth and jobs appears <span style="font-style: italic;">very</span> small. Could it really be true that the tool most readily used to manage the economy is a policy lever whose success depends as much as anything on bribing a few employed young adults to move out of their parents' basements, while at the same time exerting other contractionary effects on the economy that the mainstream fails to discuss?!?<br /><br /><span style="font-style: italic;">UPDATE (same day): Moved an incongruous paragraph and assigned it to a new Scenario E, with minor rewriting. Also added one sentence within "Other Economic Impacts."</span>hblhttp://www.blogger.com/profile/03192933210484147113noreply@blogger.com4tag:blogger.com,1999:blog-7861688742346636904.post-24907632933004357572012-06-06T12:21:00.002-04:002012-06-06T13:04:28.787-04:00EconViz: Want to Design a Fun Educational Experience about Economics?An excerpt from the latest <a href="http://econviz.org/blog/2012/06/want-to-design-a-fun-educational-experience-about-economics/">post</a> at EconViz Blog (my other economics blog):<br /><p></p><blockquote style="color: rgb(0, 153, 0);"><p>Are you a good storyteller?

For example, even mainstream macroeconomics textbooks discuss their own versions of the difference between being on a gold standard and not, the choices for social safety net implementations (such as unemployment insurance), etc. Yet there are plenty of advocates for going back to a gold standard and/or completely removing the safety net -- so there is no <span style="font-style: italic;">universally</span> agreed upon policy choice in any of the above examples.<br /><br /><span style="font-weight: bold;">In a sense, to </span><span style="font-style: italic; font-weight: bold;">not</span><span style="font-weight: bold;"> describe all the relevant policy choices in the context of discussing a particular policy-related topic would be to advocate for the remaining choice(s)</span>. Thus, while I have some [small?] reservations and concerns about the job guarantee myself (despite my giving it the benefit of the doubt overall), I'm doing my best to communicate the pros and cons of each choice (including points of controversy) as I build content on <a href="http://econviz.org/">EconViz.org</a>.<br /><br />To address a possible objection -- yes there are policy choices not on the above list that <span style="font-style: italic;">don't</span> warrant description of each policy choice (e.g., "should government provide puppies for everyone?"). But MMT has shown all the above examples (and others) to be highly relevant to the goals of national governments.<br /><br />Educational resources that represent fields of knowledge such as MMT or mainstream macroeconomics generally distill the most important descriptions from both the history of that discipline and the work of the current professionals within that discipline...<br /><br />It's my understanding that <span style="font-style: italic;">all</span> current MMT-affiliated professional economists consider the employed buffer stock to be a superior policy choice to the unemployed buffer stock, thus it's no surprise that they highlight the JG the way they do in the econoblogophere (a much more informal medium than academic papers). I think they have every right to express opinions along the lines of "you'd be crazy to know about this policy option [JG] now available to most monetarily sovereign nations and not to advocate using it" in the same way that mainstream economists express individual opinions about the gold standard, minimum wage laws, etc. <span style="font-style: italic;">And</span> I think it's perfectly valid for any individual who discusses the economy in the light of MMT to judge that the "cons" of the JG concept outweigh the "pros" -- as long as that person is explicitly acknowledging both buffer stock options and describing the detailed reasoning behind his or her conclusions.<br /><br /><span style="font-style: italic;">In case I haven't been clear enough, this is my personal perspective. I make no claims that this post is consistent with the way MMT professionals view this topic.</span>hblhttp://www.blogger.com/profile/03192933210484147113noreply@blogger.com4tag:blogger.com,1999:blog-7861688742346636904.post-5851349522232132702012-05-08T18:12:00.005-04:002012-05-08T21:29:04.215-04:00The Zero Waste Jobs Program Revisited: Can We Recycle Over 80% of Trash Instead of Under 35% While Ending Involuntary Unemployment?I recently outlined an unconventional idea for a specialized jobs program implementation. If you are interested in the topic but have not read the post, please do so: <a href="http://www.thoughtofferings.com/2012/01/ultimate-job-guarantee-implementation.html">The Ultimate Job Guarantee Implementation: Can we Achieve Zero Wasted Labor AND Zero Material Waste Simultaneously?!?</a> Two excerpts:<br /><blockquote style="color: rgb(0, 51, 0);">"What if the role of job guarantee work was to "intercept" the not-currently-recycled part of the waste stream with the goal of reclaiming recyclable, reusable, and organic (compostable or biofuel-ready) materials to the maximum extent possible?"</blockquote><blockquote style="color: rgb(0, 51, 0);">"To repeat, the high level aspiration outlined here is to "kill two birds with one stone" by matching the goal of reducing human labor waste (involuntary unemployment) with the goal of reducing other external costs currently borne by society. This post focused on the "other external costs" related to materials flow and associated environmental sustainability, but are there other large-scale external costs a JG could potentially address?"</blockquote>An <a href="http://www.npr.org/2012/04/26/150735732/following-garbages-long-journey-around-the-earth?ft=1&f=1025">interview summary at NPR</a> reminded me that I spent some time researching the practicality of this after that last post (but didn't follow up). Some quotes from Edward Humes (via NPR), author of a book called Garbology:<br /><blockquote style="color: rgb(0, 51, 0);">"Americans generate more trash than anyone else on the planet: more than 7 pounds per person each day. About 69 percent of that trash goes immediately into landfills. And most landfill trash is made up of containers and packaging — almost all of which should be recycled, says Pulitzer Prize-winning journalist Edward Humes,"</blockquote><blockquote style="color: rgb(0, 51, 0);">"In a difficult economic environment, it's just crazy to take all this material and just bury it in the ground."</blockquote><blockquote><span style="color: rgb(0, 51, 0);">"The real solution is just to stop putting so much stuff in giant burial mounds, but that's a really tough nut to crack."</span><br /></blockquote>In January after the last post I researched a number of documentaries about the trash and recycling industries. One was particularly interesting: <a href="http://www.pbs.org/independentlens/garbage-dreams/film.html">Garbage Dreams</a>, a film about an unusual community:<br /><blockquote style="color: rgb(0, 51, 0);">"On the outskirts of Cairo lies the world's largest garbage village. A labyrinth of narrow roadways camouflaged by trash, the village is home to 60,000 Zaballeen — Arabic for "garbage people." The Zaballeen have survived for centuries by recycling Cairo's waste. Members of Egypt's minority Coptic Christian community, these entrepreneurial garbage workers recycle nearly all the trash they collect, maintaining what could be the world’s most efficient waste disposal system.</blockquote><blockquote style="color: rgb(0, 51, 0);">With a population of 18 million, Cairo — the largest city in the Middle East and Africa — has no sanitation service. For generations, the city’s residents have paid the Zaballeen a minimal amount to collect and recycle their garbage. Each day, the Zaballeen collect more than 4,000 tons of garbage and bring it for processing in their village, where plastic granulators, cloth-grinders, and paper and cardboard compactors hum constantly. As the world's capacity to generate trash skyrockets, Western cities boast of 30 percent recycling rates — admirable, until you compare it with the 80 percent recycling rate the Zaballeen can claim.<br /></blockquote><blockquote style="color: rgb(0, 51, 0);">In 2003, following the international trend to privatize services, Cairo sold multimillion dollar contracts to three corporations to pick up the city's garbage. Shimmering waste trucks now line the streets, but these multinational waste disposal corporations are only contractually obligated to recycle 20 percent of what they collect, leaving the rest to rot in giant landfills. As these foreign companies came in with waste trucks and begin carting garbage to nearby landfills, the Zaballeen watched their way of life disappearing."</blockquote><blockquote><span style="color: rgb(0, 51, 0);">"... Unfortunately, the ability of the Zaballeen to both acquire and process Cairo’s garbage has become harder in the last few years. Cairo’s Zaballeen are still locked out of the trash trade by the multinational companies that arrived on the scene several years ago as part of the Egyptian government’s failed attempt to overhaul the municipal waste management system."</span><br /></blockquote>I don't want to downplay the potential problems with labor-intensive attempts to minimize the waste stream. For example, from the <a href="http://en.wikipedia.org/wiki/Zabbaleen">wikipedia entry on the Zabbaleen</a>:<br /><blockquote style="color: rgb(0, 51, 0);">"The Zabbaleen community is characterized by both low health and high rates of disease, especially those related to their garbage collecting activities."</blockquote>I haven't watched Garbage Dreams or read Garbology. But, here are some observations on the broader topic:<br /><ol><li><span style="font-weight: bold;">The assumption that more labor can enable more recycling appears accurate</span> -- the Zaballeen were recycling 80-85% of Cairo's waste stream, versus as little as 20% for the corporations that replaced them.</li><li><span style="font-weight: bold;">The incentives and guidelines in place for these multinational waste disposal corporations (profit for shareholders plus whatever basic rules and regulations they have to meet) probably are NOT well aligned with the well being of the planet</span>. Based on my admittedly superficial consideration to date, this certainly seems like an area that governments should be more actively involved in (in some countries, I believe they are, but I have not researched the details). Might not a specialized job guarantee be one feasible means of achieving public purpose here? <span style="font-style: italic;">(Note: I'm <span style="font-weight: bold;">not</span> arguing that the only way a Job Guarantee program could be beneficial is by focusing on reducing external costs in this way).</span><br /></li><li>Surely a modern first world country such as the US has the resources to equip Zero Waste Jobs Program workers with <span style="font-weight: bold;">adequate tools and safety equipment to minimize health risks</span>? The Zaballeen's only sources of income were very low fees charged to residents, plus the waste material itself (selling it or products made from it) -- yet they achieved a lot with very little.<br /></li></ol>I'd be glad to hear comments, though you might first scan the <a href="http://www.thoughtofferings.com/2012/01/ultimate-job-guarantee-implementation.html">previous post</a>'s detailed list of pros and cons related to this idea (it includes recognizing the merits of source separation and of consumers reducing their own waste streams, the merits of automation when possible, social stigma concerns, etc). It would also be interesting to hear if anyone has more detailed knowledge on this topic -- such as on the economics of the waste industry or on practices outside the US that demonstrate potentially preferable alternatives to tackling these problems.<br /><br /><span style="font-style: italic;">UPDATE: Minor edits for clarity plus added one sentence at the end.</span>hblhttp://www.blogger.com/profile/03192933210484147113noreply@blogger.com1tag:blogger.com,1999:blog-7861688742346636904.post-85811861250901750432012-04-25T12:00:00.000-04:002012-04-25T12:00:39.383-04:00New Flow Visualizer and Minor Observations on MacroeconomicsIn case you missed it, yesterday I introduced a preview of the <a href="http://econviz.org/macroeconomic-circular-flow-visualizer/">Macroeconomic Circular Flow Visualizer</a> via a <a href="http://econviz.org/blog/2012/04/macroeconomic-circular-flow-visualizer-preview/">post on EconViz</a> <span style="font-style: italic;">(read the linked post to see more on possible future features and such)</span>.<br /><br />Since I don't always get around to writing the longer ThoughtOfferings posts that linger on my "to do" list, I've been thinking of posting a (still infrequent) mix of bite-sized observations on macroeconomic dynamics. (Hey, the blog is called thought offerings!) Some of them may be inspired by the EconViz visualizers. They are unlikely to be novel, and apologies if I state the obvious too often. But, if there's an occasional observation I can't remember having seen discussed explicitly elsewhere and that I find interesting, then perhaps others will find it interesting too. And if you think I draw incorrect conclusions at any time, please speak up!<br /><br />Here's one for today on the <span style="font-weight: bold;">full autonomy of macroeconomic flow injections</span>.

(At least with floating currencies, governments sovereign in their own currencies, etc...) A question I don't know the answer to -- does the mainstream macroeconomics profession in countries with persistent trade surpluses worry about foreigners running out of funds to buy their exports??? (Since they'd believe those foreign economies' other two injections have constraints).<br /></li></ul>hblhttp://www.blogger.com/profile/03192933210484147113noreply@blogger.com0tag:blogger.com,1999:blog-7861688742346636904.post-2887676583724590172012-04-11T16:39:00.000-04:002012-04-11T16:40:07.724-04:00EconViz: New Tutorial: How Loans Create Money<span style="color: rgb(0, 102, 0);">Reposting from </span><a style="color: rgb(0, 102, 0);" href="http://econviz.org/blog/2012/04/new-tutorial-how-loans-create-money/">EconViz Blog</a><span style="color: rgb(0, 102, 0);">:</span><br /><blockquote>Here is the first part of a new narrated visual tutorial:<br /><br /><a title="How Bank Loans Create Money" href="http://econviz.org/how-loans-create-money/">How Bank Loans Create Money — Explained Visually in 3 Minutes</a><br /><br />This part covers the very basics, so you're not likely to learn anything if you've followed this topic recently in the blogosphere or used the <a title="Macroeconomic Balance Sheet Visualizer" href="http://econviz.org/macroeconomic-balance-sheet-visualizer/">Macroeconomic Balance Sheet Visualizer</a>... but I hope it might be helpful to those less familiar with the topic.

(And the mainstream of course remains hopelessly unaware, stuck on inapplicable theories like IS/LM that treat financial assets like commodities!)<br /><br />Consider this chart showing the <span style="font-weight: bold;">ratio of Bank versus Non-Bank Lending in the Euro Area versus the United States</span> * (source: ECB Monthly Bulletin via <a href="http://alea.tumblr.com/post/20055479984/the-importance-of-banks-in-the-flow-of-credit-to-the">Alea</a>):<br /><br /><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgn4qMcW5a8t-cmDwDlTF1Q7y4JmXUlNPwb2q27sjrNE2Mvbz_l2eCN2y2EQca8sxZ3gQlU2EACTsy6ks7Nuhv5jPTJ9_otR9JUu1MFlz0Bu7pJ_nWhW5oQYtPc6DKgM7NhOG_OGfA0lwKX/s1600/RatioBankFinancing-US-EU.png"><img style="cursor:pointer; cursor:hand;width: 400px; height: 278px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgn4qMcW5a8t-cmDwDlTF1Q7y4JmXUlNPwb2q27sjrNE2Mvbz_l2eCN2y2EQca8sxZ3gQlU2EACTsy6ks7Nuhv5jPTJ9_otR9JUu1MFlz0Bu7pJ_nWhW5oQYtPc6DKgM7NhOG_OGfA0lwKX/s400/RatioBankFinancing-US-EU.png" alt="" id="BLOGGER_PHOTO_ID_5724985287047084866" border="0" /></a><br /><br />I've seen this difference referred to on occasion over the years, but I've never seen anyone attempt to ask or answer, "<span style="font-style: italic;">why the difference</span>?"<br /><br />I believe <span style="font-weight: bold;">the reason is that the US government issues a much greater proportion of its debt as short duration (less than one year) as compared to the Euro Area governments</span>, who rely much more heavily on longer duration debt:<br /><br /><span style="font-weight: bold;">Percentage of Euro Area Debt Maturing within One Year, by Nation, 2010</span> (Source: <a href="http://epp.eurostat.ec.europa.eu/statistics_explained/index.php/Structure_of_government_debt">Eurostat</a>)<br /><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg_f0vCKFWGnX19Mxt4xFdlKyMdy3Y2rg33fXT23Xtk6EgJzVXe7OD_pxUIE8wMbzMuekJv2E85ZnEQiNW6tJvWX1NUkIc_E-YdY-3Ls-FBKXEG1M6aQA8XpU-1eVq7EhOsDZvUxbhuAp8-/s1600/Debt_by_maturity%252C_2010.png"><img style="cursor:pointer; cursor:hand;width: 400px; height: 217px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg_f0vCKFWGnX19Mxt4xFdlKyMdy3Y2rg33fXT23Xtk6EgJzVXe7OD_pxUIE8wMbzMuekJv2E85ZnEQiNW6tJvWX1NUkIc_E-YdY-3Ls-FBKXEG1M6aQA8XpU-1eVq7EhOsDZvUxbhuAp8-/s400/Debt_by_maturity%252C_2010.png" alt="" id="BLOGGER_PHOTO_ID_5724985226304186978" border="0" /></a><br /><br /><span style="font-weight: bold;">Percentage of US Treasury Debt Maturing within One Year</span> (source: <a href="http://www.economist.com/node/14699754?story_id=14699754">The Economist</a>):<br /><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgJ8u5ZiifhRRJmiW3TGHDWpts0hCQOl2j9Bpoqb28VnjVduWxx-ux90zwwDZ-ot35pbMSRNKw7co_X_BVpbqWYI8M_2Bnahjd89gaE6AQADaAtOUAj5FI5GKT9hSwFIPTe8dkigMRl2MHk/s1600/US_Debt_LessThanOneYear.gif"><img style="cursor:pointer; cursor:hand;width: 256px; height: 248px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgJ8u5ZiifhRRJmiW3TGHDWpts0hCQOl2j9Bpoqb28VnjVduWxx-ux90zwwDZ-ot35pbMSRNKw7co_X_BVpbqWYI8M_2Bnahjd89gaE6AQADaAtOUAj5FI5GKT9hSwFIPTe8dkigMRl2MHk/s400/US_Debt_LessThanOneYear.gif" alt="" id="BLOGGER_PHOTO_ID_5724985170221532818" border="0" /></a><br /><br />Based on the charts above, the Euro Area countries seemed to average roughly 10% short duration debt (maturing within one year) and 90% long duration debt in 2009. The US government on the other hand has issued short duration debt much more heavily -- ranging from around 30% to around 45% of total treasury debt outstanding in the years leading up to 2009. (Unfortunately I couldn't find charts with dates or date ranges that exactly matched between the US and Euro Area).<br /><br />As I explained in earlier posts on money supply endogeneity, <span style="font-weight: bold;">banks seem to operate as a "lender of last resort" within the private sector</span>. If there is a temporary "excess" of people who hold short duration assets (such as bank deposits -- i.e., money -- and short duration government debt which acts a lot like "money"), then these people will be more eager to lend (aka "invest", likely through an intermediary), thus transforming those short duration assets into long duration assets (debt assets). However, without that temporary "excess" of short duration assets, banks can always step in as the "lender of last resort", since bank loans create money. Thus any temporary "shortage" of desired short duration assets within aggregated private sector portfolios will disappear as the bank loans increase the money supply! These mechanics are covered in more detail at the previous posts linked to in the first paragraph.<br /><br /><span style="font-style: italic;">(You can use this </span><a style="font-style: italic;" href="http://econviz.org/macroeconomic-balance-sheet-visualizer/">visualizer</a><span style="font-style: italic;"> to compare bank lending, bond issuance, etc)</span>.<br /><br /><span style="font-weight: bold;">Bottom line</span>: the private sector has to accept the maturity profile of the assets supplied to it by government (government debt satisfies savings desires), and builds upon that "starting point" to get to an aggregate <span style="font-style: italic;">desired</span> portfolio maturity profile. In the Euro Area, it appears that this starting point includes "not enough" short duration assets, so to satisfy borrowing needs (note: borrowing needs are an independent dynamic from portfolio preferences), the private sector relies heavily on bank loans. But in the US, the "starting point" given by government already includes a larger proportion of short duration assets, so borrowing needs are filled using a larger ratio of non-bank lending, since non-bank lending changes the portfolio mix in a way that doesn't increase the percentage of short duration assets outstanding.<br /><br />And as I've suggested before, if the US government embarked on a truly massive shock and awe style QE (many trillions of dollars of additional asset purchases) as proposed by Paul Krugman and perhaps others, it <span style="font-weight: bold;">might inadvertently "kill" a lot of the US banking system</span>, or at least kill off much of banking's traditional on-balance-sheet lending function. (Banks might still earn fees from originating loans before selling them to non-banks, and non-banks could also originate lending as they do now). And along similar lines, when MMTers sometimes suggest that the US government should not issue bonds at all, I wonder whether they are aware of the possible impacts on the banking system. Just to be clear, I'm not expressing an opinion on whether such a change would be <span style="font-style: italic;">good</span> or <span style="font-style: italic;">bad</span>, I am just pointing out that the system might be different in large and unpredicted ways.<br /><br /><span style="font-style: italic;">* DISCLAIMER</span>: The first chart only shows "External Financing for <span style="font-style: italic;">Non-Financial Corporations</span>," so a chart that also included household borrowing <span style="font-style: italic;">might</span> tell a very different story that could contradict the analysis in this post. It seems improbable to me that there is a massive reliance by European households on non-bank lending that would be large enough to offset the corporate reliance on bank lending, but I'd be glad to hear if I'm wrong.<br /><br />UPDATE 2:21pm:<span style="font-weight: bold;"><br />First</span>, I realize I failed to discuss how the propensity of US households toward bank borrowing versus non-bank borrowing (of unknown amount) could change the premise I introduced with the first chart by making the Euro Area and US look more alike when considering the entire private sector's borrowing rather than just corporate borrowing.<br /><span style="font-weight: bold;">Second</span>, the title read as more definitive than I originally intended, so I added a question mark -- this blog post's content (statements often prefixed by "I believe...") is still <span style="font-weight: bold;">largely speculative</span>, though there seems to be supporting evidence in the Circuitist literature (as I interpret it).hblhttp://www.blogger.com/profile/03192933210484147113noreply@blogger.com3tag:blogger.com,1999:blog-7861688742346636904.post-47488625322545425012012-03-06T16:25:00.000-05:002012-03-06T16:26:09.786-05:00Tutorial Seeking the Right Audience<span style="color: rgb(0, 102, 0);">Reposting from </span><a style="color: rgb(0, 102, 0);" href="http://econviz.org/blog/">EconViz Blog</a><span style="color: rgb(0, 102, 0);">:</span><br /><br /><a href="http://econviz.org/how-the-economy-works-visual-tutorial/">How the Economy Works — a Visual Tutorial</a> seeks the right audience of would-be learners.

The economic motivations include (1) achieving loose "full employment" even when there is insufficient aggregate demand (spending) to create private sector jobs for everyone who wants one, and (2) enhancing macroeconomic price stability (low and stable inflation), and (3) raising the long term productivity of the economy. Job Guarantee (JG) proponents are among those who consider <span style="font-weight: bold;">mass involuntary unemployment to be an enormous waste of willing human labor</span>, resulting in many direct and indirect costs to society. And even <a href="http://www.federalreserve.gov/newsevents/testimony/bernanke20110713a.htm">Ben Bernanke has said</a>:<br /><blockquote style="font-style: italic;">"Long-term unemployment imposes severe economic hardships on the unemployed and their families, and, by leading to an erosion of skills of those without work, it both impairs their lifetime employment prospects and reduces the productive potential of our economy as a whole."</blockquote>One of the recurring topics of JG debate is "what would all these people do?" Some commenters have a variety of constructive answers to this question, while others suggest than any job tasks chosen by the government (even local government, as opposed to Congress) would be a "boondoggle." I am not familiar enough with the academic research and modeling to weigh in with strongly held opinions for or against the JG concept in general (though I lean strongly toward giving it the benefit of the doubt), but this post will outline a concrete JG idea I have not seen described elsewhere. There are aspects of the idea I find highly compelling, but I expect some people may hate it.<br /><br />First, some brief context. Modern economies have major problems with their environmental sustainability. One of these problems is that they have evolved to treat natural resources as an "input" to human activity and accepted a large waste stream as an "output", as though the economy were the center of reality. There have always been some observers warning that <span style="font-weight: bold;">economies exist WITHIN the natural environment, not APART from it</span>, and economies must adapt to function in a sustainable closed-loop way just like natural ecosystems -- where the output of every system of production and consumption is ultimately an input to another such system. Here is a diagram from <a href="http://www.zerowaste.org/case.htm">zerowaste.org</a> reflecting the current economic system's material flows:<br /><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh5S3YFC0B3s5zLrbmppbLa8whktV41BQmsokXiONeep2jlmUPF_e4vQRWwpQCAlU9fqwp-OCkx2UebQWX94cxhxpHWS0pXI_-aW07S4JM7G_bOzrpSMfr3Dn-nRVXbeLeMcFS6kya_aALn/s1600/material_flows_current.gif"><img style="cursor:pointer; cursor:hand;width: 400px; height: 280px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh5S3YFC0B3s5zLrbmppbLa8whktV41BQmsokXiONeep2jlmUPF_e4vQRWwpQCAlU9fqwp-OCkx2UebQWX94cxhxpHWS0pXI_-aW07S4JM7G_bOzrpSMfr3Dn-nRVXbeLeMcFS6kya_aALn/s400/material_flows_current.gif" alt="" id="BLOGGER_PHOTO_ID_5696864084154131026" border="0" /></a><br />Here is a diagram reflecting the conceptually ideal zero-waste closed loop system:<br /><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEha3ps0NlxilAapSN-xFye-A8gm8Y6_iR-5GckRp4Qavo0IdHJlJi1vbWlu0vl-7ntnyayotXvSHSJHyvXGqBnF9yk5o1bf7CsN5_hIIx_qNLm5Bh4FigPJTBmXKhIVB0ZrsQfrWvSkGwvD/s1600/material_flows_zero_waste.gif"><img style="cursor:pointer; cursor:hand;width: 400px; height: 261px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEha3ps0NlxilAapSN-xFye-A8gm8Y6_iR-5GckRp4Qavo0IdHJlJi1vbWlu0vl-7ntnyayotXvSHSJHyvXGqBnF9yk5o1bf7CsN5_hIIx_qNLm5Bh4FigPJTBmXKhIVB0ZrsQfrWvSkGwvD/s400/material_flows_zero_waste.gif" alt="" id="BLOGGER_PHOTO_ID_5696864140056880786" border="0" /></a><br />Three of the major problems with the current system as shown in the first diagram are <span style="font-weight: bold;">external costs</span>, that is, costs borne by society at large:<br /><ol><li>Land fills consume finite land (for which available locations are diminishing), and can be unpleasant and costly to administer.</li><li>Garbage incineration contributes to air pollution that adversely effects health, and consumes many materials that might have had better forms of reuse.</li><li>The economy's raw material input requirements are larger than would be necessary if we reused more of our waste stream. In addition, the methods we use to extract new raw materials typically have large external costs as well (e.g., habitat destruction and pollution from mining). These external costs go down when we reuse more materials.</li></ol><p style="font-weight: bold;"><span style="color: rgb(204, 0, 0);">What if the role of job guarantee work was to "intercept" the not-currently-recycled part of the waste stream with the goal of </span><a style="color: rgb(204, 0, 0);" href="http://en.wikipedia.org/wiki/Resource_recovery">reclaiming</a><span style="color: rgb(204, 0, 0);"> recyclable, reusable, and organic (compostable or biofuel-ready) materials to the maximum extent possible?</span><span style="font-weight: normal;"> Source separation (such as separate curbside bins) should certainly still be encouraged wherever possible to create pre-separated streams of recyclables, organic waste (yard and food scraps), and general trash, however many localities don't do any separation at all, and even general trash streams will inevitably contain recoverable waste. <span style="font-weight: bold;">So a JG zero-waste program would focus specifically on reducing the waste streams that are currently going to landfills or incinerators.</span></span></p><p style="font-weight: bold;"><span style="font-weight: normal;">The pie chart below shows the composition of the 250 million ton annual waste stream in the US, of which only 34% is currently recycled! (Source: <a href="http://www.epa.gov/osw/nonhaz/municipal/">EPA</a>). That <span style="font-weight: bold;">66% currently going to landfills and incinerators contains extraordinary amounts of valuable material! Separating it further would be labor intensive work</span>, and would probably not be profitable for individual companies extracting only the materials they could sell for more than the cost of labor. But, the job guarantee concept isn't intended to be "profitable" in such a narrowly focused sense!<br /></span></p><p style="font-weight: bold;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjUimbmu5g9ZF2WFn_4B3iVO2tIvkwGW-CW-GfZVZ-uI8hvOcFE9kOutg561rLbEQ8DHAqunIZSuqp9fdwFDWCFk8S1AeCce87bbKsBdy_S2Q0ojnoq8wkk84BHRCfkULDBYR3uQaUvHkpP/s1600/US_waste_stream_contents.jpg"><img style="cursor:pointer; cursor:hand;width: 400px; height: 333px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjUimbmu5g9ZF2WFn_4B3iVO2tIvkwGW-CW-GfZVZ-uI8hvOcFE9kOutg561rLbEQ8DHAqunIZSuqp9fdwFDWCFk8S1AeCce87bbKsBdy_S2Q0ojnoq8wkk84BHRCfkULDBYR3uQaUvHkpP/s400/US_waste_stream_contents.jpg" alt="" id="BLOGGER_PHOTO_ID_5696873947320269602" border="0" /></a></p><span style="font-weight: normal;">An underlying presumption in this idea is that the more human labor is available for sorting, separation, and dis-assembly of complex items, the higher would be the percentage of the waste stream that can be reclaimed for new uses. There would likely be diminishing returns in adding new labor as separation of reusable materials approaches 100% of the waste stream -- since some portion of the waste stream may be too complex or contaminated for separation -- but this also means <span style="font-weight: bold;">a potentially huge number of JG workers could be usefully employed, so the JG program <span style="font-style: italic;">could</span> be exclusively focused on this goal</span>!

Single-stream recycling facilities already have impressive technology for separation of material types, and technologies for processing "dirty" trash streams appear to be advancing too! But based on my limited knowledge, even these advanced "dirty" processing facilities still require some human labor in the sorting process, and may also be too expensive for many municipalities. We are probably still decades away (I'm guessing!) from sophisticated enough computer vision and robotic dexterity to achieve everything a human can in this type of process.<br /><br />I expect this to be a controversial suggestion, in part because of the "trash" association and concerns about human dignity (perhaps this is an inherently bad idea!) but I'll run through some of the pros and cons I can think of.</span> Here are some advantages:<ul><li><span style="font-weight: bold;">Job guarantee workers would be providing an obvious-to-all public service with broadly shared benefits</span>, because the waste stream is produced by just about everyone, and the negative externalities being reduced would otherwise be suffered widely also. With other JG roles sometimes suggested by commenters (reading to the elderly, planting trees in parks, removing graffiti, etc) there might be concerns by voters about jobs benefiting some demographics more than others, or about potentially poor choices of projects in general. But everyone benefits from a zero material waste economy!<br /></li><li>If a program of this type intercepted the part of the waste stream not already being reclaimed, it <span style="font-weight: bold;">would not compete with the private sector or charities</span> (or perhaps very minimally). Presumably this work is too labor intensive to be cost effective for private industry, but cost effectiveness (with the typical narrow definition of a single entity's cash flow) is not the goal of the job guarantee.</li><li>It is inherently <span style="font-weight: bold;">local</span> (which is one of the MMT design choices for implementing a JG), because waste streams are produced everywhere people live and work!</li><li>The financial costs of waste handling are often already paid for by municipalities (<a href="http://en.wikipedia.org/wiki/Waste#Costs">source</a>).<br /></li><li>The <span style="font-weight: bold;">savings</span><span style="font-weight: bold;"> in materials-flow-related external costs</span> alone (pollution, landfill space, and raw material inputs to the economy) could significantly offset the program's "costs" in terms of wages paid to JG workers (not that a JG program should be required to be provably "profitable" to be considered a success).</li><li>After also accounting for the <span style="font-weight: bold;">benefits to society of reduced involuntary unemployment</span> (e.g., reductions in mental illness, crime, family breakdown, soup kitchen spending, safety net transfer payments, etc) such a program would look even more cost effective!</li><li>It would <span style="font-weight: bold;">scale easily with the </span><span style="font-weight: bold;">ever-changing </span><span style="font-weight: bold;">size of the JG's buffer pool of workers</span>. If the economy booms and the JG pool shrinks and there is no fiscal adjustment made by federal government to increase the pool (potentially needed if inflation were accelerating), then more of the waste stream will simply end up in the landfill or incinerator as is the practice today. Thus "zero" waste would be an exaggeration, but the waste reduction might still be large. Conversely, if the economy contracted and the JG pool of workers grew large, perhaps the sorting process could focus on reclaiming a much larger percentage of the waste stream, possibly even with extra time to break down and disassemble complex waste into component parts. What would the "typical" size of the JG pool of workers be? At least one MMT economist has suggested it might average around 3% of the work force.<br /></li><li>Waste sorting and separation jobs would be <span style="font-weight: bold;">easily filled by unskilled labor</span>, consistent with the "hiring off the bottom" goal of the JG.</li><li>A job guarantee is widely recognized as setting a floor on economy-wide wages. However, it might also set a floor on conditions. Some commenters have expressed concern that having too many jobs viewed as "easy" in a JG (reading, tutoring, etc?) could be a problematic competitive force attracting workers from private sector jobs to the JG. An assumption in this thinking is that society relies on some industries in which the work can't be made "fun" and "easy" and while there should certainly be safe and humanitarian working conditions enforced, those industries' attempts to pay enough to retain workers might result in problematically large shifts in private sector wage structures, potentially raising the general price level by enough to force the nominal JG wage too far below a "living wage" to be politically acceptable. Thus, for better or worse, waste stream handling as a choice of JG program would be likely be <span style="font-weight: bold;">seen by voters as not setting an overly "cushy" floor for work conditions</span>.</li><li>Waste handling is a large enough problem that it might (?) be able to absorb ALL JG workers (even if that represents 3% or more of the work force).</li><li>Waste handling is a national and global problem so best practices could be shared widely across implementations.<br /></li><li>Such a program might be able to piggy-back on <span style="font-style: italic;">some</span> existing infrastructure.<br /></li><li>Such a program might not be seen by voters as "make work" (see CETA-related quote <a href="http://www.thoughtofferings.com/2012/01/what-are-lessons-of-ceta-1973-us-jg.html">here</a>), and thus have <span style="font-weight: bold;">higher political feasibility than some JG suggestions?</span><br /></li></ul><p>Here are some potential drawbacks:</p><ul><li>There could be a large <span style="font-weight: bold;">social stigma</span> for JG workers handling society's waste in this way. But would it be worse than the social stigma of unemployment? And might society's notions of dignity be able to evolve? After all, one of nature's waste handlers, the scarab (a type of dung beetle), was considered sacred in Ancient Egypt...<br /></li><li>Concerns may arise about the <span style="font-weight: bold;">moral hazard</span> for households and businesses in knowing that someone will "clean up after them." But with a national emphasis on good practices in sustainability, hopefully there could be ways to minimize this. And certainly manufacturers and such whose waste output is already regulated should continue to bear a higher responsibility (enforced by regulation) for minimizing their waste streams. (Often this process turns out to be <a href="http://www.natcap.org/">profitable for them anyway</a>.)<br /></li><li>Such a program might not be "transitional" enough -- <span style="font-weight: bold;">does it adequately prepare workers for transition to the private sector</span> when a job becomes available? I don't know, and I'm not sure how favorably it would compare in this respect to other job types suggested for unskilled labor in JG programs.</li><li>Could the potential for unsanitary organic waste (dirty diapers!), sharp metal or glass, hazardous chemicals, etc make it <span style="font-weight: bold;">too dangerous</span>? Are there standards for hazmat suits and assistive tools and technology that would suffice? Even assuming so, there would need to be some sort of externally administered inspection process to ensure safe working conditions.</li><li>Could such work inherently lead to <span style="font-weight: bold;">repetitive stress injuries</span>? I'm not sure how highly repetitive such sorting tasks would be given the nature of a mixed waste stream -- it could include some interesting dis-assembly of a big variety of items (toys, electronics, furniture, etc) into their component pieces. Perhaps every certain number of hours would involve a shift in the "creative project" room designing and building the [mini-]pyramids for the 21st century and other art out of the waste not useable for other applications!</li><li><span style="font-weight: bold;">Separability of materials might be too difficult</span> if organic waste can cause too much contamination... but this might be addressed with larger source separation initiatives (curbside food and garden waste containers) along with a willingness to send unrecoverable bags or clumps of trash to the landfill-bound conveyer.</li><li><span style="font-weight: bold;">Energy use</span> for sorting, transportation, and reuse might be more of a limiting factor than the needed human labor. If getting the separated materials back into the industrial production stream in a useable form required too much energy, such a project might not be popular (at least until further strides are made in renewable energy). Of course, the organic waste stream may itself be an energy source given ongoing <a href="http://en.wikipedia.org/wiki/Waste-to-energy#WtE_technologies_other_than_incineration">innovations in waste-to-energy technology</a>.</li><li>Some new infrastructure (facilities and equipment) might be required. This could actually be beneficial to the economy if there was enough spare economic capacity to build and produce what was required within putting undesirable upward pressure on prices.<br /></li></ul>Aside from the drawbacks above and whatever else I've overlooked or gotten wrong, this almost seems too good to be true! What do you think?<br /><br />To repeat, <span style="font-weight: bold;">the high level aspiration outlined here is to "kill two birds with one stone" by matching the goal of reducing human labor waste (involuntary unemployment) with the goal of reducing other external costs currently borne by society.</span> This post focused on the "other external costs" related to materials flow and associated environmental sustainability, but are there other large-scale external costs a JG could potentially address?hblhttp://www.blogger.com/profile/03192933210484147113noreply@blogger.com11tag:blogger.com,1999:blog-7861688742346636904.post-68097260317174841572012-01-13T14:15:00.006-05:002012-01-15T19:01:43.052-05:00What are the lessons of CETA? (a 1973 US jobs program)Last May I ran into a reference to a jobs program started in 1973 called CETA (Comprehensive Employment and Training Act) that at its peak employed more than 700,000 people. At the time I searched the major MMT blogs as well as the papers I could find on Job Guarantee / Employer of Last Resort policy and implementations, and I didn't find any discussion of it. I posted comments asking about it on a couple major MMT blogs, but no one weighed in at the time. It occurred to me given the recent JG discussions to ask again, and a search in my feed reader hasn't uncovered any new references to it. <span style="font-style: italic;">(Disclaimer: my lack of results could be entirely my failure to search thoroughly enough.)</span><br /><blockquote></blockquote>Overview from wikipedia:<span style="font-style: italic;"> “a United States federal law enacted in 1973 to train workers and provide them with jobs in the public service… The program offered work to those with low incomes and the long term unemployed… The intent was to impart a marketable skill that would allow participants to move to an unsubsidized job. It was an extension of the Works Progress Administration program from the 1930s. The Act was intended to decentralize control of federally controlled job training programs, giving more power to the individual state governments.”</span><br /><br />An opinion writer at politicsdaily that had came up in my quick search results said: <span style="font-style: italic;">“That was the crux of the policy dilemma: The voters did not want make-work and the unions did not want real work.” And, “CETA employees did perform useful work — from asbestos removal to assisting in libraries and senior citizen centers.” And, “Following the questionable gospel that state and local governments always know best, CETA programs were decentralized.” And, “But the problem with CETA was not that it embodied Big Government, but that it was not big enough.”</span><br /><br />The program sounds like it shares a number of characteristics with the Job Guarantee as proposed by primary MMT authors, and it's more recent than the Great Depression work programs that people often mention in comments. So, what did it do right? What did it do wrong? What are the lessons learned? Why is it not being used as an example in these discussions, or mentioned by primary MMT authors? (Perhaps it has been and I've just missed it). Was it successful for its size (despite not being an unlimited offer of work positions at the policy wage, as proposed under a JG) but just not big enough to matter? Were there major unintended consequences that weren't addressed? Was it ultimately sabotaged on ideological grounds by free market fundamentalists? Did the voters and the unions reject it on the grounds quoted above? Anyone know or have useful links that I've overlooked?<br /><br />UPDATE 1/15/2012: Corrected the first paragraph. It had falsely referenced Jimmy Carter as associated with the start of this program (either I mangled the notes I took a year ago or the original source I found was wrong -- I should have caught that presidential year mistake -- oops!)hblhttp://www.blogger.com/profile/03192933210484147113noreply@blogger.com4tag:blogger.com,1999:blog-7861688742346636904.post-63215468932603482922012-01-11T15:11:00.001-05:002012-01-11T15:13:51.070-05:00Kaldor on Money Supply EndogeneitySome of my posts starting in October 2010 (the most recent one is <a href="http://www.thoughtofferings.com/2011/06/visual-guide-to-endogenous-money-and.html">here</a>, with some conceptual graphics) have focused on the endogeneity of the money supply <span style="font-style: italic;">independent from the broad Post-Keynesian observation that loans create deposits</span>. That is, <span style="font-weight: bold;">the dynamism of the economy (largely courtesy of the financial sector) seemingly allows households and businesses on aggregate to self-determine their portfolio composition -- i.e., how much "money" they hold -- independent of both government policy and private debt levels</span>.<br /><br />Whether due to lack of familiarity or considered relative unimportance, there seems to be very little attention to this dynamic in the MMT-oriented econoblogosphere, even among the "primary" MMT bloggers when they discuss QE. If money supply endogeneity were only about loans creating deposits, then one should still expect to see QE changing broad money supply from whatever trend(s) it was already on, since QE isn't generally assumed to change people's propensity to borrow or their rate of deleveraging. Here are two updated charts of the MZM (Money Zero Maturity) measure of broad money supply:<br /><br /><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEip30RDIHcZ3nAJeoRrK4IvrndDRMmv2EsVNdZw_Qrba3QFTsxDIE0WgBn1ZOirtzYzXDrFIUn9EKdYJFrbO6OmJjpbuRIBJjfvu4lSGhvbplHNtc2JfFNWKgp6mkQ71vNqXaEZoGQ80w-J/s1600/MZM-annotated.png"><img style="cursor:pointer; cursor:hand;width: 400px; height: 240px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEip30RDIHcZ3nAJeoRrK4IvrndDRMmv2EsVNdZw_Qrba3QFTsxDIE0WgBn1ZOirtzYzXDrFIUn9EKdYJFrbO6OmJjpbuRIBJjfvu4lSGhvbplHNtc2JfFNWKgp6mkQ71vNqXaEZoGQ80w-J/s400/MZM-annotated.png" alt="" id="BLOGGER_PHOTO_ID_5696462145161109410" border="0" /></a><br /><br /><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgL0-y91nT0WWpauz2s5-YQoLB3Z63wQfEovLUvb7Q675qEgmwEAqRpaNV5T5ruvCSq7kO7RVZ0hMmRv51pymrBXusEAVIO9UaZjyGVjVUPGpGmMTimfrKaPEREjzJY_w3Ed9dozHks4p67/s1600/MZM-YoY-annotated.png"><img style="cursor:pointer; cursor:hand;width: 400px; height: 240px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgL0-y91nT0WWpauz2s5-YQoLB3Z63wQfEovLUvb7Q675qEgmwEAqRpaNV5T5ruvCSq7kO7RVZ0hMmRv51pymrBXusEAVIO9UaZjyGVjVUPGpGmMTimfrKaPEREjzJY_w3Ed9dozHks4p67/s400/MZM-YoY-annotated.png" alt="" id="BLOGGER_PHOTO_ID_5696462197430117282" border="0" /></a><br /><br />Money supply did not grow as much as the QE operations alone would suggest. The actual trends are very volatile (probably having to do with uncertainty and liquidity preference during recession and expanding financial assets in line with a growing economy during economic growth) and so it's difficult to say anything conclusive other than that QE did not provide a 1-to-1 increase or obviously "shift" the trend lines while active.<br /><br />Ramanan recently posted two great quotes from Nicholas Kaldor's The Scourge Of Monetarism (Oxford University Press, 1982). First, <a href="http://www.concertedaction.com/2011/12/24/merry-christmas/">via Ramanan</a> (emphasis mine):<br /><blockquote>"As it is, <span style="font-weight: bold;">a highly developed banking system</span> already provides such facilities on an ample scale, since it <span style="font-weight: bold;">is prepared to accommodate the public’s changing demand between different types or financial assets by altering the composition of the banks’ assets or liabilities in a reverse direction</span>. If the non-banking public wishes to switch its holding of gilts for interest-bearing bank deposits, the banks are ready to supply such deposits at the minimum of inconvenience, and at the same time to place their surplus funds into the gilts which were previously held by the public. Similarly the banks provide easy facilities to their customers for switching balances on current accounts into interest-bearing deposit accounts, or vice versa. Hence, while the annual increment in the total holding of financial assets of the private sector (considered as a whole) is nothing more than the mirror-image of the borrowing requirement of the public sector (in a closed economy at any rate), <span style="font-weight: bold;">neither the Government nor the banks can determine how much of this increment will be held in the form of cash (meaning notes and current deposits)</span> and how much in the near-equivalents to cash (such as interest-bearing demand deposits) or in various forms of public sector debt. Thus neither the Government nor the central bank can control how much or the total financial assets the public prefers to hold in the form of ‘money’ on one particular definition or another."</blockquote>Kaldor certainly appears to have these concepts mastered (including financial sectoral balances) and this was 1982! It's amazing to me that virtually none of this could "rub off" onto the economics mainstream over a period of three decades! Ramanan quotes <a href="http://www.concertedaction.com/2012/01/10/more-from-nicholas-kaldor/">more interesting details from Kaldor in a second post</a> (follow the link to read it).<br /><br />This seems to me largely consistent with <a href="http://www.thoughtofferings.com/2011/06/visual-guide-to-endogenous-money-and.html">dynamics I've postulated</a>. A copy and paste from my last post's summary of mechanisms:<br /><u></u><blockquote style="color: rgb(102, 102, 102);"><u>Overview of Ways the Private Sector Can Reduce "Unwanted" Broad Money Supply</u>:<br /><ol><li><span style="font-weight: bold;">Replace loans (which create money) with non-bank borrowing (which does not create money) independent of total debt levels.</span> Examples of non-bank debt include corporate bonds, peer to peer loans, securitized loan pools, housing agency debt, etc. Most of this post focused on this mechanism.<br /></li><li><span style="font-weight: bold;">Induce less bank lending by changing aggregated propensities to borrow. For example, many reports indicate a record number of </span><a style="font-weight: bold;" href="http://pragcap.com/all-cash-buyers-prevent-housing-market-collapse">cash buyers have been supporting the housing market</a><span style="font-weight: bold;">.</span> Logically, if there is an "excess" of deposits in the economy, then investors who would rather own other assets may outbid other potential buyers of those same assets who would have bought using debt. Thus, while QE's added money supply in this case doesn't eliminate existing bank loans, it serves to reduce the number of houses bought using bank loans, while at the same time other loans are continually being paid down. The net effect is that bank lending moves to a lower level than it would have been at had QE not occurred. Those who lost the bid for houses (who would otherwise have bought with a bank loan) might rent from the investors instead, so this point does not imply that QE will cause some to have no place to live.<br /></li><li><span style="font-weight: bold;">Banks can sell assets (treasuries, loans, etc) to the rest of the private sector.</span> A net decrease in assets in this way causes a net decrease in broad money supply. To see how this works, visit the <a href="http://econviz.com/balance-sheet-visualizer.html">Macroeconomic Balance Sheet Visualizer</a>, and choose the operation "Bank Loan" followed by "Bank Loan is Securitized" (which is one way banks sell assets to the non-bank sector).</li><li><span style="font-weight: bold;">Banks can fund themselves with a higher portion of non-deposit liabilities (e.g., bonds) instead of deposit liabilities.</span> This results in less broad money supply. As I understand it, this was part of the dynamic that RSJ described in <a href="http://windyanabasis.wordpress.com/2011/04/22/pushing-on-a-string-in-pictures/">this post</a>.</li></ol></blockquote>I'm not sure whether I'm odd to find this stuff fascinating or whether my descriptions are not clear and/or don't seem credible (and I admit I still may have some things wrong!). It may just be that this is clearly less important than topics on "fixing" the economy's current primary problems. But I've considered putting together a mini step-by-step visualization on <a href="http://econviz.org/">EconViz</a> on this topic (when I can get to it) -- if anyone would find this beneficial in clarifying these interactions, please say so.hblhttp://www.blogger.com/profile/03192933210484147113noreply@blogger.com7tag:blogger.com,1999:blog-7861688742346636904.post-7959678065104608652012-01-11T13:33:00.000-05:002012-01-11T13:33:43.527-05:00The US Becoming Japan... not in the way you may think!It has become common in recent years to suggest that the US is headed the way of Japan, with the implication being that Japan has been an economic failure in recent decades. (I starting expecting in the early 2000s that the US would follow Japan, also, but for some right and some wrong reasons). Last year and again today I've <a href="http://www.thoughtofferings.com/2012/01/myths-about-japans-stagnation-revisited.html">highlighted</a> the huge degree to which Japan's economic performance is a story about demographics and the confusion about nominal versus real in the context of periodic mild deflation.<br /><br />However, by failing to adequately support US economic growth (that is, incomes and employment) in the wake of the "Great Recession", policy makers may yet find a way to send us down Japan's path:<br /><blockquote>"A sharp decline in fertility rates in the United States that started in 2008 is closely linked to the souring of the economy that began about the same time, according to a new analysis of multiple economic and demographic data sources by the Pew Research Center." -- <a href="http://www.pewsocialtrends.org/2011/10/12/in-a-down-economy-fewer-births/">In a Down Economy, Fewer Births</a></blockquote>and<br /><br /><a href="http://www.reuters.com/article/2011/12/21/us-population-grows-slow-idUSTRE7BK24T20111221">U.S. population grows at slowest rate since 1940s</a><br /><br />So, poor economic growth could become a self-fulfilling prophecy via the demographic channel itself!<br /><br />Of course I'm exaggerating for effect. The drop off in US fertility rate (about a 7% fall from 2007 to 2010) is not yet anywhere near large enough to give the US a demographic outlook like Japan's... plus there are long lags in demographic effects, and other factors such as immigration rate. And according to <a href="http://www.nytimes.com/2012/01/08/opinion/sunday/the-true-story-of-japans-economic-success.html">Eamonn Fingleton</a> the reasons for Japan's demographics are quite different:<br /><blockquote>"The story begins in the terrible winter of 1945-6, when, newly bereft of their empire, the Japanese nearly starved to death. With overseas expansion no longer an option, Japanese leaders determined as a top priority to cut the birthrate. Thereafter a culture of small families set in that has continued to the present day."<br /><br />"Japan’s motivation is clear: food security. With only about one-third as much arable land per capita as China, Japan has long been the world’s largest net food importer. While the birth control policy is the primary cause of Japan’s aging demographics, the phenomenon also reflects improved health care and an increase of more than 20 years in life expectancy since 1950."</blockquote>Nevertheless, if US policy makers were to sabotage the US economy further by actively imposing austerity, we might yet follow in Japan's economic path (or worse) but in a different way than typically suggested!<br /><br />I should also note that I'm not suggesting that higher population growth rates are inherently better, just that they contribute to economic growth (for better or worse). I recognize the planet's finite resources are being strained, but I am also a mild optimistic regarding our ability to accelerate "radical resource productivity" with the right fixes to the political system and the current massive problems of externalized costs.hblhttp://www.blogger.com/profile/03192933210484147113noreply@blogger.com0tag:blogger.com,1999:blog-7861688742346636904.post-90817507361376199612012-01-11T00:53:00.001-05:002012-01-11T16:07:22.291-05:00Myths about Japan's Stagnation RevisitedAlmost a year ago I posted two graphs and some comments on <a href="http://www.thoughtofferings.com/2011/04/real-gdp-per-capita-and-myths-about.html">Real GDP Per Capita and Myths about Japan's Stagnation</a>.

I had myself been interested in the per-working-age-resident data as compared to the per-capita data, since changes in the participation rate (partly due to demographics) could cause the two to differ, but hadn't gone to the trouble of getting the data. Unfortunately Paul Krugman starts at 1990 rather than 1980 and so I'm not sure his conclusion tells the full story:<br /><blockquote>"This picture suggests that the Japanese economy was indeed depressed for about 16 years, and deeply so after the slump of the late 1990s. But it may have returned to more or less potential output on the eve of the current crisis."</blockquote>Look at my second graph (above) and you can see the extraordinary growth in the late 1980s in Japan. Was this growth "above potential"? Was Japan somehow borrowing from the future in the 1980s, and are the Austrians correct that slower growth in the 1990s to undo the "excesses" and get back to the trend line must be an inevitable outcome? (I do think the answer is closer to "no" than "yes", but don't have all the answers for how/why).<br /><br />Is the correct framing Krugman's, i.e., that Japan stagnated from 1990 onward and didn't return to the potential growth trend line for a decade and a half? Or is the more accurate framing that Japan's growth accelerated above trend line in the 1980s and took a decade to revert to the trend line? (In a mostly smooth fashion, excepting the unfortunate 1997-ish austerity, rather than a crash and depression!)<br /><br />I believe MMT shows how the "hangover" theory of economic growth is wrong (as opposed to asset prices, which MMTers generally agree must be allowed to adjust after bubbles pop). This is because it is always possible for the flow of national income to be sustained by government deficits or net exports even if the leakage to private sector savings increases. Perhaps there was a massive inventory effect from overbuilding of real estate in the 1980s, requiring less building in the 1990s. Should that or other dynamics have pushed unemployment so low as to cause accelerating inflation? Glancing at some graphs it appears Japan's late 1980s unemployment got down to around 2%, with inflation rising to around 4%. What would have happened if the economy hadn't slowed after 1990? Would inflation have accelerated upwards uncontrollably? It doesn't seem obvious that it would, but I don't know the answers.<br /><br />If not an "overbuilding" dynamic or a labor force participation dynamic (not yet investigated), then perhaps the majority of the late 1980s surge can be explained by a huge above-trend rise in productivity. If so, is there any implication that productivity will inevitably grow below trend after such a surge? It doesn't seem like such a reversion should be inevitable, but perhaps there are dynamics specific to the types of productivity improvements in Japan in that time frame that would provide more answers.<br /><br />Comments and insight are welcome.<br /><br />I'll split a few more observations on demographics into a separate post to keep this from getting too long.hblhttp://www.blogger.com/profile/03192933210484147113noreply@blogger.com4tag:blogger.com,1999:blog-7861688742346636904.post-43226432431264078742011-11-22T14:01:00.001-05:002011-11-22T14:03:15.841-05:00New EconViz Blog & Survey ResultsThanks to those of you who have tried out the preview draft version of the <a href="http://econviz.org/how-the-economy-works-visual-tutorial/">How the Economy Works Visual Tutorial</a> and submitted feedback! <span style="font-style: italic;">(And thanks Tom for the extra traffic from your post).</span><br /><br />I have created a dedicated <a href="http://econviz.org/blog/">blog for EconViz.org</a> on which I'll announce major content and functionality updates to that site. Feel free to subscribe to the <a href="http://econviz.org/blog/feed/">RSS Feed</a> if you are interested in seeing what unfolds there and perhaps giving further feedback.

There are a number of good reasons for this, but I think concept visualization is still behind where it should be (at least in the educational material I've been exposed to).<br /><br />Macroeconomics is a subject extremely well suited to conceptual visualization, yet the majority of the educational material on the web seems to be text-centered (other than supply-demand curves and the occasional simple diagram or balance sheet). While equations such as “GDP = C + I + G + ( X – M )” provide precision and rigor and aren't even mathematically complex, their inclusion in content (for example, blog posts) necessarily narrows the potential audience.<br /><br />As most readers know, my first attempt at concept visualization for macroeconomics was the <a href="http://econviz.org/macroeconomic-balance-sheet-visualizer/">Macroeconomic Balance Sheet Visualizer</a>. However, it did not appear to be as accessible to newcomers as I'd initially hoped. So I've been working on something intended for a broader audience.<br /><br />Design goals include:<br /><ul><li>Anchor as much of the verbal content to visual representations as possible, to reduce ambiguity and help illustrate concepts</li><li>Be as concise as possible while covering the most important core concepts</li><li>Have the core content be beginner friendly, but have additional details available just a click away at each step along the path for those who want more</li><li>Use a web site rather than blog format, so the content can be evolved and improved in-place over time</li></ul>While the content and illustrations are very far from complete (think of it as an evolving framework still in the rough draft stage), I think it's crossing a threshold where it could be worth having available to the public while work on it continues. (There's a chance I will take it offline again for a while if I get the impression it may do more harm than good in its current form).<br /><br />My “to do” list is enormous for it... there is much much more that can be done graphically as well with better verbal coverage of concepts. It simply takes time... And you'll also have to excuse the amateurish graphics, for now.<br /><br />That said, it's very useful to get feedback to help prioritize the “to do” list, plus you may have creative suggestions that aren't on my list! Also I hope you'll help keep me on track with direct and honest feedback (including negative reactions) if you think parts of it are heading in the wrong direction, or I've messed up or left out important things! If you do choose to try this new visualizer and respond, you can give anonymous feedback directly from a link at the bottom of each page in the tutorial, or you can post comments to this blog post, or email me.<br /><br />And if you're just learning MMT and are short on time, you may want to just wait for a future improved version rather go through what's there now, since it's full of gaps and placeholders.<br /><br />Here it is:<br /><br /><a href="http://econviz.org/how-the-economy-works-visual-tutorial/">http://econviz.org/how-the-economy-works-visual-tutorial/</a><br /><br />P.S.

As stated previously, it's possible I've reached some incorrect conclusions, however my interpretation of a piece of Post-Keynesian Circuitist literature I was referred to suggests to me that these ideas are on the right track.<br /><br /><u>Basic QE Mechanics</u><br /><br />Some people have read that the direct mechanics of Quantitative Easing only increase bank reserves but not deposits (broad money supply). That is true only in the narrow case where banks are net sellers of bonds from their own balance sheets to the Federal Reserve. But the evidence suggests banks have not drawn down their net bond assets in this way since QE began (the Fed has bought over $2 trillion in bonds!), and that the primary sellers are non-banks. To see why the immediate mechanical result of this is for QE to increase bank deposits (and thus broad money supply), please visit the <a href="http://econviz.com/balance-sheet-visualizer.html">Macroeconomic Balance Sheet Visualizer</a> and run the operation "Quantitative Easing (Variation 1 - Households Sell)". Also, see this <a href="http://www.newyorkfed.org/education/lsap/index.html">guide from the NY Fed</a>:<br /><blockquote style="font-style: italic;">"When the Fed buys an asset, the effect on the broad money supply depends on who sold the assets and what they do with the funds they receive. If the seller is a bank, reserves go up, but broad money only increases if the bank responds to the increase in its reserves by lending more to households and businesses. <span style="font-weight: bold;">If the seller is an investor other than a bank, reserves go up, and broad money also goes up in the first instance as the seller's bank puts a sum equal to the amount it receives from the Fed into the seller's bank account.</span> But if the seller uses the money to pay down debt, the broad money supply declines again by the amount of the debt repayment. As of early 2011, the behavior of the broad money supply, economic activity and inflation all suggested that recent money growth had not been excessive."</blockquote>The guide mentions the well known idea that the broad money supply increase resulting from QE has been muted due to debt repayment, but as my past posts have indicated, I think that's only half the story.<br /><br /><u>Actual Broad Money Supply Changes During QE</u><br /><br />The first graph shows broad money supply as measured by MZM (Money Zero Maturity), the second graph shows the year on year change.<br /><br /><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEih_IArJTYLE3lYLIy_h4ykDM2N-yAqQkw4S6-HvIGirP2Voccb6N0UXClcjZ17qUD3ghKYW37fSp4NTb7m6cRqxCDOYpJ-uXVvJoINgO8zAc8aQc0Xi4ec4HL_mB7fXr5KiKF8VwKSyL0i/s1600/MZM.png"><img style="cursor:pointer; cursor:hand;width: 400px; height: 240px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEih_IArJTYLE3lYLIy_h4ykDM2N-yAqQkw4S6-HvIGirP2Voccb6N0UXClcjZ17qUD3ghKYW37fSp4NTb7m6cRqxCDOYpJ-uXVvJoINgO8zAc8aQc0Xi4ec4HL_mB7fXr5KiKF8VwKSyL0i/s400/MZM.png" alt="" id="BLOGGER_PHOTO_ID_5621122521640050418" border="0" /></a><br /><br /><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhzx75gvSGhzmr41IzOqwoMMNQhD8RGQDeMKSnO7OwP2GRONXJEp6heHJscXufoLa7HpmTXJTwuR9_04edUrJ_dc_k_GEUsSjOgM69PJYfFZw5O4D3NUHrAH_wl31MtiTwj4FNmmNPUVm3h/s1600/MZM_delta.png"><img style="cursor:pointer; cursor:hand;width: 400px; height: 240px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhzx75gvSGhzmr41IzOqwoMMNQhD8RGQDeMKSnO7OwP2GRONXJEp6heHJscXufoLa7HpmTXJTwuR9_04edUrJ_dc_k_GEUsSjOgM69PJYfFZw5O4D3NUHrAH_wl31MtiTwj4FNmmNPUVm3h/s400/MZM_delta.png" alt="" id="BLOGGER_PHOTO_ID_5621122578511338130" border="0" /></a><br /><br />It's not obvious that either QE program had a direct impact on the broad money supply trends, even though they should have if you consider only the direct mechanical results of the Fed buying bonds, and don't consider any private sector response! Of course it is difficult to tell for sure, as the money supply changes for lots of reasons besides just QE (e.g., it generally expands during economic growth, but perhaps also during times of uncertainty).<br /><br />So where did part of the roughly $2 trillion in "money" that replaced bonds go? Did it only "disappear" to the extent that the private sector wanted to pay down debt? I've argued that it disappeared INDEPENDENTLY of whatever level of desire there was to pay down debt, and that the money supply growth that did occur would have occurred to almost the EXACT SAME DEGREE even if QE had not happened. In other words, money supply grew because the private sector "wanted" a larger money supply as part of its aggregated portfolio preferences.<br /><br /><u>A Visual Guide to Money Supply Endogeneity</u><br /><br />First, consider the general situation in which bank loans expand the broad money supply. The "Bank Loans" and "Bank Credit" bars are the same size by identity because loans create deposits:<br /><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj9WKfnkj-z-dtpajjDssSje7xg-UzJIw1FYREEE7OenwbLKIJRotQRUP1xpAYg42O1teiCQLSMvnN5VFZhtRRvX5uDWKtw3QuOD3mjvdWsWacS6P7UEHtvgIm6uWyZn9y3j-mruOUdplfF/s1600/EndogenousMoney_1of3.png"><img style="cursor:pointer; cursor:hand;width: 578px; height: 315px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj9WKfnkj-z-dtpajjDssSje7xg-UzJIw1FYREEE7OenwbLKIJRotQRUP1xpAYg42O1teiCQLSMvnN5VFZhtRRvX5uDWKtw3QuOD3mjvdWsWacS6P7UEHtvgIm6uWyZn9y3j-mruOUdplfF/s600/EndogenousMoney_1of3.png" alt="" id="BLOGGER_PHOTO_ID_5621125216626207618" border="0" /></a><br /><br />Next, consider what happens during Quantitative Easing in terms of the immediate mechanical result. Broad money supply expands, "backed" by an increase in excess reserves held by the banking system:<br /><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj0iLB9a0CYl4YhO0zqt3jSCe_rY7n_dlT6e11lvnllkp1OwCIYZrbc73kd4OEFU3aH544EL0M1IOaQV4NIqnqHCYZTqUpC-xOxZhxSM3Eue2kwjqM29mfqZiPM6VTD891Lq12XKxHb1Fka/s1600/EndogenousMoney_2of3.png"><img style="cursor:pointer; cursor:hand;width: 578px; height: 240px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj0iLB9a0CYl4YhO0zqt3jSCe_rY7n_dlT6e11lvnllkp1OwCIYZrbc73kd4OEFU3aH544EL0M1IOaQV4NIqnqHCYZTqUpC-xOxZhxSM3Eue2kwjqM29mfqZiPM6VTD891Lq12XKxHb1Fka/s600/EndogenousMoney_2of3.png" alt="" id="BLOGGER_PHOTO_ID_5621125269190142450" border="0" /></a><br /><br />The private sector controls all quantities with white labels. Excess reserves, with a yellow label, is the only quantity here fully controlled by government! The light yellow label on Required Reserves indicates partial control. Banks lend first and look for needed reserves later, and the Federal Reserve's open market operations ensure that reserves sufficient to meet reserve requirements will automatically become available (either as a result of the Fed buying/selling treasuries as part of OMO, or via loans from the Fed). So the quantity of Required Reserves adjusts in response to changes in the quantity of Bank Loans, and the government only controls the size of Required Reserves if it changes the rules.<br /><br />Lastly, consider how the private sector can work to "undo" the change in money supply imposed by QE, without having to alter its borrowing desires!<br /><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiY09VPcnSQbFNnsJAykUFGckEI5cLd0PT7Tl6WFnac9UtQV2GOOGHCovpDxBBmfqmJOCYaMtGZYs3SqPVvtFbRiLvBThulJbAb8WpX58CIGofmKNEU13nGOqZPdZ5CVntbAa8w6gk43iRi/s1600/EndogenousMoney_3of3.png"><img style="cursor:pointer; cursor:hand;width: 577px; height: 319px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiY09VPcnSQbFNnsJAykUFGckEI5cLd0PT7Tl6WFnac9UtQV2GOOGHCovpDxBBmfqmJOCYaMtGZYs3SqPVvtFbRiLvBThulJbAb8WpX58CIGofmKNEU13nGOqZPdZ5CVntbAa8w6gk43iRi/s600/EndogenousMoney_3of3.png" alt="" id="BLOGGER_PHOTO_ID_5621125326361294882" border="0" /></a><br /><br />One of the reasons bank loans can be replaced by other forms of borrowing (perhaps with a lag?) is that when you look inside the aggregates, the economy is very dynamic under the surface. There are always some households and companies borrowing new money, others making debt repayments and others completely paying off debt.<br /><br />Some bank loans may be repaid early and replaced by non-bank borrowing, but in general there is always new borrowing being done, even when the big picture is one of deleveraging.<br /><br />When there is "excess" money and investors would rather hold bond assets, those investors will likely outbid banks in the contest to fund new borrowing needs. That is how the mix of bank debt versus non-bank debt can be affected. Even unconventional borrowing markets may play a part in this, such as "peer-to-peer" lending (going to family and friends for a loan instead of to the local bank). Another example of non-bank borrowing is new corporate equity issuance — perhaps angel investors and the like are outbidding banks on meeting funding needs, too.<br /><br /><u>Overview of Ways the Private Sector Can Reduce "Unwanted" Broad Money Supply</u>:<br /><ol><li><span style="font-weight: bold;">Replace loans (which create money) with non-bank borrowing (which does not create money) independent of total debt levels.</span> Examples of non-bank debt include corporate bonds, peer to peer loans, securitized loan pools, housing agency debt, etc. Most of this post focused on this mechanism.<br /></li><li><span style="font-weight: bold;">Induce less bank lending by changing aggregated propensities to borrow. For example, many reports indicate a record number of </span><a style="font-weight: bold;" href="http://pragcap.com/all-cash-buyers-prevent-housing-market-collapse">cash buyers have been supporting the housing market</a><span style="font-weight: bold;">.</span> Logically, if there is an "excess" of deposits in the economy, then investors who would rather own other assets may outbid other potential buyers of those same assets who would have bought using debt. Thus, while QE's added money supply in this case doesn't eliminate existing bank loans, it serves to reduce the number of houses bought using bank loans, while at the same time other loans are continually being paid down. The net effect is that bank lending moves to a lower level than it would have been at had QE not occurred. Those who lost the bid for houses (who would otherwise have bought with a bank loan) might rent from the investors instead, so this point does not imply that QE will cause some to have no place to live.<br /></li><li><span style="font-weight: bold;">Banks can sell assets (treasuries, loans, etc) to the rest of the private sector.</span> A net decrease in assets in this way causes a net decrease in broad money supply. To see how this works, visit the <a href="http://econviz.com/balance-sheet-visualizer.html">Macroeconomic Balance Sheet Visualizer</a>, and choose the operation "Bank Loan" followed by "Bank Loan is Securitized" (which is one way banks sell assets to the non-bank sector).</li><li><span style="font-weight: bold;">Banks can fund themselves with a higher portion of non-deposit liabilities (e.g., bonds) instead of deposit liabilities.</span> This results in less broad money supply. As I understand it, this was part of the dynamic that RSJ described in <a href="http://windyanabasis.wordpress.com/2011/04/22/pushing-on-a-string-in-pictures/">this post</a>.<br /></li></ol><u>Implications</u><br /><br />Why does this matter? To the extent that these dynamics really occur as described in my three posts so far:<br /><ol><li>This shows in even stronger terms why Quantitative Easing as practiced so far (targeting quantities rather than prices) has had no meaningful effect other than on sentiment. <span style="font-weight: bold;">QE truly was a placebo.</span></li><li>It lends even more power to the concept that <span style="font-weight: bold;">money is always debt and can NOT be modeled like a commodity</span>. Its quantity is extremely dynamic and subject to the portfolio desires of the private sector. IS/LM curves and the like are not relevant. One of the arguments by the Fed was that QE would increase deposits in portfolios relative to the supply of available bonds and provide a bid under other assets due to "formulaic" institutional portfolio investing, but the premise of persistently expanded money supply and reduced longer duration assets appears to be false.<br /></li><li>It lends even more weight to the idea (frequently argued by MMTers) that<span style="font-weight: bold;"> interest rates are determined independently of borrowing demand, and thus that there can be no financial crowding out of the private sector when the government issues debt</span>! Economy-wide interest rates truly are anchored to the short term Fed Funds rate plus expectations of future rate settings. (Not that the market can always consistently estimate future rate settings!)</li><li>Conventional wisdom is that one goal of QE was to help the banking system. <span style="font-weight: bold;">Ironically, QE may have hurt banks more than it helped them!</span> The banking system seems to operate as a private sector lender of last resort, and by triggering a shift to additional direct (non-bank) lending, QE seems to have reduced the role of banks in the economy, and thus reduced their potential to accrue earnings from loans!</li></ol>UPDATE 6/23/2011: Made a few minor edits for clarity, and added Implication #4.

I think a "double dip" is very possible but if I had to guess, I don't think a new recession is the most probable scenario in the near term. But that depends on difficult factors to predict such as whether current US congressional antics really are only short term theater as many allege, and the potential size of negative demand shocks from the rest of the world (China, Europe, other various housing bubble countries like Australia and Canada, etc).<br /><br />I believe a common mistake is to consider high oil prices to be one of the drags on growth. <span style="font-style: italic;">Rising </span>oil prices are certainly a drag on growth, but stable oil prices (once lagged effects of previous changes have dissipated) are growth neutral, as I understand it. Even the generally excellent Calculated Risk might have gotten this wrong in a recent <a href="http://www.calculatedriskblog.com/2011/06/key-question-is-slowdown-temporary.html">outlook post</a> where he says "<span style="font-style: italic;">Also the recent decline in oil and gasoline prices will help, although $100 oil is still a drag on the economy.</span>" However he could be correct if he considers a drag on the economy to be a separate phenomenon from a drag on economic growth. (If you think I'm the one who's gotten this wrong, please let me know!)<br /><br />Similarly, deleveraging is not a drag on growth unless the rate of deleveraging increases. Deleveraging is just one determinant of the household savings rate. A stable household savings rate is growth-neutral. However, deleveraging does reduce the likelihood of a <span style="font-style: italic;">falling </span>savings rate and the associated boost to GDP growth that such a shift would provide. So in terms of current economic growth (i.e., ignoring impacts on future growth), steady-state deleveraging is the absence of a positive rather than an actual negative.<br /><br />Note that this post only focused on GDP growth... clearly we still have crisis levels of unemployment and underemployment that policy makers should be actively working to address!<br /></div>hblhttp://www.blogger.com/profile/03192933210484147113noreply@blogger.com7tag:blogger.com,1999:blog-7861688742346636904.post-60804855177619322052011-04-21T18:03:00.001-04:002011-04-21T18:08:25.864-04:00Further Evidence that the Private Sector Fully Controls the Money Supply and QE Doesn't "Work" as AdvertisedIn October, I wrote a post titled <a href="http://www.thoughtofferings.com/2010/10/how-loanbond-choice-helps-private.html">How the Loan/Bond Choice Helps the Private Sector Self-Determine the Money Supply — AND Yet Another Reason QE is a Non-Event for the Economy</a>. To give a brief summary, it described my thoughts on the inter-relational dynamics between debt, money supply, and Quantitative Easing, as follows:<br />
<ol><li>There are two high level ways that borrowing occurs in the private sector — bank loans, and all other forms of borrowing, i.e., bond issuance, securitization, peer to peer lending, etc.</li>
<li>When there is an "excess" of short duration assets (primarily money) held by the private sector, the holders of those assets will be eager to lend it out, and thus acquire a higher yielding asset. The money supply remains unchanged.</li>
<li>When there is no "excess" of money to lend (i.e., portfolio preferences are satisfied with the current levels), then banks will have a higher propensity than non-bank lenders to fulfill the economy's current borrowing needs, because they can lend an [almost] unlimited amount, independent of their level of money/reserves. (Their only limit on lending to worthy borrowers, and it is temporary, is how much equity capital they can raise). Bank lending increases the money supply, so from a macro perspective, <b>banks could be considered the private sector's lender of last resort</b>.</li>
<li>By choosing the relative proportion of the two type of borrowing, <b>the private sector is able to choose its portfolio mix of long duration assets and short duration assets (money)</b>, independently of the actions of the federal government, and [mostly] independently from the desired level of private sector borrowing!</li>
<li>When the Federal Reserve conducts Quantitative Easing, it buys long duration assets (treasury bonds, etc) out of the private sector, and gives the private sector short duration assets (money balances) instead.</li>
<li><b>If the private sector is not happy with this new portfolio mix resulting from QE, it likely has the power to "undo" the change over time via shifts in the proportion of bank loans versus other types of lending that it uses!</b></li>

<br />
<b><u>Possible Evidence from a Post-Keynesian Expert that this Theory may be Correct</u></b><br />
<br />
In the comments of my previous post, commenter Ramanan helpfully linked to a <a href="http://cas.umkc.edu/econ/economics/faculty/wray/631Wray/Week%205/Lavoie%20%28Circuit%20and%20Stock%20Flow%29.pdf">PDF from Marc Lavoie</a>, one of the leading Circuitists. Circuitists (also known as horizontalists) are one "school" of theory within Post-Keynesian economics, and they share most of the same concepts as Modern Monetary Theorists. In section 9.3.1, Lavoie seems to describe the same dynamic that I have attempted to describe. Here is an excerpt:<br />
<blockquote>"...for apparently <b>the demand for money and the supply of credit are determined by two independent mechanisms</b>. In the Lavoie and Godley (2001-2002) model for instance, <b>the demand for credit, at the end of the period, depends on the part of investment expenditures which has not been financed by retained earnings and new equity issues</b>..."</blockquote><blockquote>"...the decision by households to hold on to more or less money balances has an equivalent compensatory impact on the loans that remain outstanding on the production side."</blockquote>While Lavoie only mentions "equity issues", I have seen evidence elsewhere that he uses that term as shorthand to describe any non-bank borrowing mechanism employed by a firm, i.e., his reference to "equity issues" is supposed to also encompass bond issues and some other types of liabilities.<br />
<br />
For reasons that are unclear to me, some MMT authors repeatedly claim that QE does not add to the broad money supply. While it is true that if the primary dealers sell their own treasuries to the Fed, then only base money supply is affected, this scenario is too limited given the size of QE to date. As I understand it, primary dealers frequently act as an intermediaries to facilitate QE buying assets from the larger private sector. <b>But if the private sector can react relatively quickly enough </b><b>via the mechanisms described here </b><b>to "undo" the money supply changes, then the money supply data won't show any bulge in broad money supply resulting from QE!</b> (And of course there are other factors impacting the money supply at the same time, primarily a desired deleveraging within the private sector, so it is probably not possible to disentangle these different dynamics when looking at the data.)<br />
<br />
<u><b>Evidence in the Recent Data for the QE in the United States</b></u><br />
<br />
In the <a href="http://www.thoughtofferings.com/2010/10/how-loanbond-choice-helps-private.html">last post on this topic</a>, I showed a graph of Japan's bank and non-bank borrowing. While inconclusive, it suggests that Japan's Quantitative Easing from 2001-2006 may have caused a relative decrease in bank-based borrowing as compared to non-bank borrowing, which could add to evidence of the theories above.<br />
<br />
Below is a graph of US borrowing from Q2 2004 to Q1 2011.<br />

The red line shows the annualized percentage change in bank loans and leases, by quarter. The green line shows the annualized percentage change in total private sector debt (from the Z.1 report, which is not yet available for Q1 2011). The blue line shows the annualized percentage change in non-financial private sector debt (since the private sector's debt has many layers that could overwhelm the other trends, I thought it worth separating financials out.) I have not subtracted bank loans out of the total debt data, so the shape of the blue and green lines is slightly impacted by the shape of the red line (though the absolute amount of bank debt is around $7 trillion versus around $41 trillion for total private sector debt, so crossover impact is not huge).<br />
<br />
<b>Notice how bank loans declined substantially faster than total debt after the first round of Quantitative Easing started!</b> The gap between the red line and the blue line is probably the most relevant. Despite tracking closely to each other until late 2008, they diverged significantly starting in 2009, perhaps as the private sector favored non-bank lending on a relative basis over bank lending, in order to "shed" the excess money supply imposed by quantitative easing!<br />
<br />
The second round of quantitative easing is smaller in magnitude, and the data so far only covers the start of QE2. However, in Q4 2010 the gap between the red and blue lines appears to begin widening again. Will that effect continue? I would guess so, but I could ultimately prove to be wrong.<br />
<br />
It is also not clear how big the lag effects in this process are. Also, the changes in bank loans versus total debt diverged most significantly in the middle of QE1, and the gap narrowed partially before QE1 ended. It could be that other dynamics that I am unaware of provide a more accurate explanation than what I suggest here.<br />
<br />
<u><b>Anecdotal Evidence</b></u><br />
<br />
While it's far from scientific or conclusive, and I don't follow the details of specific financial markets, I occasionally see anecdotal evidence of the private sector's increased eagerness for non-bank lending. For example:<br />

In generating the chart in this post, I discovered the importance of using the percent change bank loan data as prepared by the Federal Reserve in its H.8 release whenever possible, instead of starting with the absolute levels of loans. The latter's level jumps around too much due to balance sheet consolidations, acquisitions, etc, while the percent change data appears to be adjusted to remove this effect, if I am understanding it correctly. Details are on the <a href="http://www.federalreserve.gov/releases/h8/about.htm">about page</a> and <a href="http://www.federalreserve.gov/releases/h8/h8notes.htm">notes page</a>.hblhttp://www.blogger.com/profile/03192933210484147113noreply@blogger.com29tag:blogger.com,1999:blog-7861688742346636904.post-68063547680628162072011-04-12T14:15:00.008-04:002011-05-24T09:26:51.507-04:00Real GDP Per Capita and Myths about Japan's StagnationWhile addressing some myths about Japan, Bill Mitchell <a href="http://bilbo.economicoutlook.net/blog/?p=14133">posted</a> some graphs of contributions to real GDP. His graphs cover the same <a href="http://www.thoughtofferings.com/2010/08/real-gdp-growth-in-us-and-japan-closer.html">data I graphed last August</a> -- the contributions of Consumption, Investment, Government Spending, and Net Exports toward inflation-adjusted economic growth. (A minor difference is I separated Inventories and other Investment in my graphs). Bill also usefully added in Ireland while emphasizing the negative effects of austerity on growth. Visuals such as these make it obvious that <span style="font-weight: bold;">investment falls under austerity</span> -- it doesn't rise on a supposed swell of increased business confidence that austerity proponents often claim will be triggered!<br /><br />While I've been guilty of parroting some myths on Japan myself in years past, it has been enlightening to put more effort into reviewing the data for myself. Here is a graph I have been meaning to post for quite a while:<br /><br /><span style="text-decoration:underline">Annual Growth of Real GDP Per Capita in the US and Japan (1980-2009)</span><br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh2oVpLt1um_P_1OWYO4kvQzEBgvz6AU-PAz1ResaFntJwV_uXwDe0siFWgzYiO_uyL4VB_gKxATn_HVovPbd9t6gV3ARqRvbPM1rxPF_q7JQ-rt-tPCUZpChVmq-2J7OKSPMgacGbEl9gk/s1600/RealGDPPerCapita_US_Japan_1980-2009.png"><img style="clear:both; margin:0 10px 10px 0;cursor:pointer; cursor:hand;width: 400px; height: 240px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh2oVpLt1um_P_1OWYO4kvQzEBgvz6AU-PAz1ResaFntJwV_uXwDe0siFWgzYiO_uyL4VB_gKxATn_HVovPbd9t6gV3ARqRvbPM1rxPF_q7JQ-rt-tPCUZpChVmq-2J7OKSPMgacGbEl9gk/s400/RealGDPPerCapita_US_Japan_1980-2009.png" alt="" id="BLOGGER_PHOTO_ID_5594749625736849154" border="0" /></a><br /><br />The blue line is for Japan, the red line for the US. <span style="font-weight: bold;">It is quite astonishing how close in both magnitude and direction US and Japanese growth have been, when adjusted for population changes!</span> The main divergences are Japan's burst of higher growth in the late 1980s, and its austerity-driven recession in the late 1990s. Once you adjust real GDP growth for changes in population, what you are left with is largely productivity growth. There are other factors that affect the level of GDP (and important things like employment!) but they have less effect on year-on-year growth rates once the adjustment has occurred.<br /><br /><span style="font-weight: bold;">Japan's famous deleveraging primarily meant a higher savings rate than before the deleveraging (corporate rather than household, in Japan's case), with the main effect being a one time shift downward in GDP level (but not growth).</span> After the GDP shift caused by a savings rate shift, future and ongoing GDP growth is impacted by other factors such as whether aggregate demand is sufficient to bring growth back near potential growth, but Japan may have been a success story in this area! However, its success in achieving this real per-capita GDP growth may have been more a result of the falling household savings rate over the last couple decades than of government fiscal (or monetary!) policy.<br /><br />Japan's stagnation myths (some people blame too much government spending, others too little!) derive in part from two sources of confusion -- real growth versus nominal growth (Japan has a low and sometimes negative rate of inflation) and GDP growth versus per capita GDP growth (Japan has a low-to-negative population growth trend).<br /><br />Of course, real GDP growth (absolute rather than per-capita) does affect valuations of financial markets and real estate, since those valuations rely on the size of future earnings streams. Japan's asset markets have famously failed to "recover." To the extent that other nations follow in Japan's demographic footsteps, there will be some downside surprises in asset market returns in the medium to long term for many advanced nations...<br /><br />UPDATE (same day):<br /><br />To supplement the year-on-year growth chart above, here is a graph of the actual levels of per capita real GDP indexed for Japan and the US. Japan's surging growth in the late 1980s that accompanied its stock market and real estate bubbles did put it above the US trend, but the levels converge again before year 2000.<br /><br /><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjyIEOb_GLaycszRCoYiLtorrxnZ77AtmRirlXc21ZmXTMI8ZOnbFNK7i19HRkdmCcfmTlPAT7kdyQoUzuaNzwycd7sF9fUEcd9M75GV03BksD6hsDHtf1BMhiLaL1mTHNFS9SYU8LacPAi/s1600/RealGDPPerCapita_US_Japan_1980-2009_index.png"><img style="clear:both; margin:0 10px 10px 0;cursor:pointer; cursor:hand;width: 400px; height: 240px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjyIEOb_GLaycszRCoYiLtorrxnZ77AtmRirlXc21ZmXTMI8ZOnbFNK7i19HRkdmCcfmTlPAT7kdyQoUzuaNzwycd7sF9fUEcd9M75GV03BksD6hsDHtf1BMhiLaL1mTHNFS9SYU8LacPAi/s400/RealGDPPerCapita_US_Japan_1980-2009_index.png" alt="" id="BLOGGER_PHOTO_ID_5594783948959889682" border="0" /></a><br /><span style="font-style: italic;"><br />UPDATE 5/23/2011: After reading a <a href="http://bilbo.economicoutlook.net/blog/?p=14584">post by Bill Mitchell</a> today that appeared to contradict the findings in this post, I initially wondered whether I had erred by using the FRED2 data for Japan in which the real per capita GDP data is converted to 2009 US dollars at purchasing power parity. (i.e., perhaps this incorporated exchange rate effects as well.) However, today I extracted the appropriate source data from Japan's cabinet office and generated my own graph using yen-denominated values, and the trend line is identical to the FRED2 data I used. In other words, the trend lines for per capita GDP growth for the US as measured in dollars and Japan as measured in yen still are remarkably consistent with each other, just as this post initially showed. The main divergences in the two trends are in the time periods of roughly 1987-1990 and 1997-2000.<br /><br />It turns out (based on my own graphs from the source data) that Bill seems to have accidentally switched the labels on the two lines in his second graph, so his nominal and real GDP per capita lines for Japan are reversed.</span>hblhttp://www.blogger.com/profile/03192933210484147113noreply@blogger.com2tag:blogger.com,1999:blog-7861688742346636904.post-51200617730688357022011-03-30T14:58:00.001-04:002011-03-30T15:02:11.237-04:00Nonfinancial Corporate Earnings: Could They Keep Falling Until the Economy Passes Through Another Recession?While I ponder aloud whether this is a healthy stock market for investors (as opposed to momentum traders), this will be my second post on the topic, following the <a href="http://www.thoughtofferings.com/2011/03/stock-market-earnings-trends-what.html">last post that graphed long term trends in earnings</a>.<br /><br />I tend to avoid analyses that take the form of "<span style="font-style: italic;">whenever A happened in the last B years, then C occurred at least D percent of the time.</span>" Much of the time this indicates data mining to validate a favored conclusion, whether bullish or bearish. While this post risks getting closer to that territory than I'd like, I'm going to avoid actually calculating percentages and such and keep it vague and qualitative! I have no clear conclusions, I simply found the data interesting.<br /><br />Here is a graph of nonfinancial corporate business profits after tax (NFCPATAX) and financial corporate business profits after tax (CP minus NFCPATAX) from the national accounts data, generated via <a href="http://research.stlouisfed.org/fred2/">FRED2</a>.<br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiXavEK3xuL37O_nSnisGzhmQELFfTNyYKBvwSQ2PLh_vF97IwCivEigcF5x_fSdyYlnBJzsa9kvqHnZEGfBID-SgrfHOgPazSApeBNyfjakCHNFruyZGZsuur3b6fUdYlS3yYPaKKu7Qvk/s1600/Nonfinancial_and_Financial_Profits.png"><img style="clear:both; margin:0 10px 10px 0;cursor:pointer; cursor:hand;width: 400px; height: 240px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiXavEK3xuL37O_nSnisGzhmQELFfTNyYKBvwSQ2PLh_vF97IwCivEigcF5x_fSdyYlnBJzsa9kvqHnZEGfBID-SgrfHOgPazSApeBNyfjakCHNFruyZGZsuur3b6fUdYlS3yYPaKKu7Qvk/s400/Nonfinancial_and_Financial_Profits.png" alt="" id="BLOGGER_PHOTO_ID_5589935506865890418" border="0" /></a><br /><ul><li><span style="font-weight: bold;">Nonfinancial profits (the blue line) fell a nontrivial amount in Q4 2010</span>.

Note that I am intentionally graphing nominal profits in all cases, rather than a ratio such as to GDP. This is because stock prices are likely more sensitive to nominal profits than profits ratios.<br /><br />A natural question for an investor would be, what are the implications for stock prices?<br /><br />Here is a graph of nonfinancial corporate profits and the value of the S&P 500 index:<br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgcoTrHwEEVanYKF2xVhPr6LDaBxYBaerWNL8LP5i-ghSCgSWH337Np3h6JwOA69Wrd7YPR3ktcJkiwpZsWznjlXZNE_kjeGn_JOAR3NmnUyNQ8Yise_WQ3sk6XpYRAYesTn84BMxrR76DO/s1600/Nonfinancial_Profits_and_SP500.png"><img style="clear:both; margin:0 10px 10px 0;cursor:pointer; cursor:hand;width: 400px; height: 240px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgcoTrHwEEVanYKF2xVhPr6LDaBxYBaerWNL8LP5i-ghSCgSWH337Np3h6JwOA69Wrd7YPR3ktcJkiwpZsWznjlXZNE_kjeGn_JOAR3NmnUyNQ8Yise_WQ3sk6XpYRAYesTn84BMxrR76DO/s400/Nonfinancial_Profits_and_SP500.png" alt="" id="BLOGGER_PHOTO_ID_5589935628070682050" border="0" /></a><br />Does the point at which nonfinancial earnings peak represent an "overvalued" stock market price, given that recession often follows within a few years? It appears that in many cases, the stock market continued to rise after earnings peaked, and the eventual stock market low during recession wasn't always lower than the stock price had been at the time of that prior peak in earnings. Thus, waiting to buy stocks wouldn't necessarily have provided a lower entry point in the future. There are of course exceptions, for example the most recent recession taking stock prices well below their price at the time of the prior peak in nonfinancial earnings.<br /><br />I can suggest no insights from this data regarding the eventual impact on stock prices even if the current contraction in nonfinancial earnings continues. The future direction of financial sector earnings may turn out to be a key determinant of the outcome. Plus, as is well known, valuation multiples expand and contract independently from changes in earnings.<br /><br />Here is the same data repeated but only up to 1992, so the vertical scale for the earlier years is more clear:<br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjfKFF4U9GVBEFhey1pUUPGLvRz2bCMGAdXLBC8yel8OriA14JhF0DbzNbzLBh7Y84J1wUWhE9DxgFetikyi3nPV6nsG1BHAneXwE82jeiZmUPIsFrp0Ru6CUbYf-sEF7z01eP_IlQXZJet/s1600/Nonfinancial_Profits_and_SP500_to_1992.png"><img style="clear:both; margin:0 10px 10px 0;cursor:pointer; cursor:hand;width: 400px; height: 240px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjfKFF4U9GVBEFhey1pUUPGLvRz2bCMGAdXLBC8yel8OriA14JhF0DbzNbzLBh7Y84J1wUWhE9DxgFetikyi3nPV6nsG1BHAneXwE82jeiZmUPIsFrp0Ru6CUbYf-sEF7z01eP_IlQXZJet/s400/Nonfinancial_Profits_and_SP500_to_1992.png" alt="" id="BLOGGER_PHOTO_ID_5589935682752697554" border="0" /></a><br /><img src="http://econviz.com/footer-1.gif?d=EarnRecess201103" alt="" border="0" />hblhttp://www.blogger.com/profile/03192933210484147113noreply@blogger.com0tag:blogger.com,1999:blog-7861688742346636904.post-22375668955093218142011-03-24T14:11:00.002-04:002011-03-24T14:56:41.188-04:00Stock Market Earnings Trends: What Happens This Decade?What is the outlook for US stock market returns over the coming decade? There is no shortage of commentary on this topic, and I don't have any unique answers, but I thought I would share two graphs.<br /><br />A lot of market commentary suggests the stock market is overvalued on the basis of measures such as stock market capitalization to GDP, Shiller's CAPE (10 Year Average Inflation-Adjusted PE ratio), Tobin's Q, etc. But for any elevated ratio, a reversion to the mean can occur via a combination of falling numerator and/or rising denominator. For example, GDP could grow rapidly while stock market valuation grows slowly, allowing the ratio of market cap to GDP to mean revert without a fall in earnings and stock prices. But how likely is the numerator to fall? That is what would most concern a medium to long term investor.<br /><br />One prediction in particular that caught my attention was <a href="http://pragcap.com/robert-shiller-the-sp-will-rally-13-in-the-coming-9-years">Robert Shiller's suggestion</a> that the S&P 500 will be around 1430 in the year 2020. With the S&P 500 currently around 1300, that represents roughly a 10% <span style="font-style: italic;">total </span>increase (not annual!) over a decade. Robert Shiller is known for recognizing both the dot-com bubble and housing bubble long before most people, so he is worth listening to.<br /><br />Here is a chart of trailing 12 month reported earnings created from <a href="http://www.econ.yale.edu/%7Eshiller/data.htm">Shiller's spreadsheet</a>, from 1871 through Q3 2010:<br /><br /><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiTuvuPGzavEZpiEygVzBDCQT6cLvrJ8tY9x-D9u6CXlER5-JUkfRs6U1XboHWpLhihitZv0BdsV7xttrjAbWkiKvuIbjXdfMiN-Ed7lLEss5R5wOugsHWJvF-hAMLXzOFW8yraXptopL2a/s1600/Real_Earnings_Trend.png"><img style="clear:both; margin:0 10px 10px 0;cursor:pointer; cursor:hand;width: 400px; height: 221px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiTuvuPGzavEZpiEygVzBDCQT6cLvrJ8tY9x-D9u6CXlER5-JUkfRs6U1XboHWpLhihitZv0BdsV7xttrjAbWkiKvuIbjXdfMiN-Ed7lLEss5R5wOugsHWJvF-hAMLXzOFW8yraXptopL2a/s400/Real_Earnings_Trend.png" alt="" id="BLOGGER_PHOTO_ID_5587697362061946818" border="0" /></a><br /><br />The green exponential trend line shows the long term earnings trend. Current earnings have rebounded quickly to well above the trend line. If earnings oscillate around this trend line as they have done historically, they should be centered around roughly $60 in 2020! At a 15 valuation multiple, that only represents an S&P 500 index value of 900 (a 31% decline!) However, this trend is for real (inflation adjusted) earnings, so the nominal level of earnings and corresponding S&P 500 valuation would be somewhat higher assuming continued positive inflation.<br /><br />But what about the most optimistic case from the perspective of the stock market? What if we are in a sustainable new era in which the recent extraordinary corporate margins, earnings to GDP, etc, can be maintained indefinitely? The next graph shows the same trend line since 1980 but for nominal reported earnings. The red portion of the line is the estimated forward earnings from <a href="http://www.standardandpoors.com/indices/sp-500/en/us/?indexId=spusa-500-usduf--p-us-l--">Standard & Poors S&P500 spreadsheet</a> as of today, which is important because expected earnings represent what the market valuation is currently priced for, i.e., earnings of $90-$95.<br /><br /><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgFQG0BxPpi0sOEGo6p6ZIIFNv96Vuh5Y04AuJgy-FGKYrq5MS3VULTnOMdPHFMTKf5qHojRyvMvsIu-e9v-lEIgTA6-wuO_8ZbyjZ8eoTp9sJPCrstxPHMCe541H2Zbm7OfRM5xVsLqPHc/s1600/Nominal_Earnings_Trend_Since_1980.png"><img style="clear:both; margin:0 10px 10px 0;cursor:pointer; cursor:hand;width: 400px; height: 249px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgFQG0BxPpi0sOEGo6p6ZIIFNv96Vuh5Y04AuJgy-FGKYrq5MS3VULTnOMdPHFMTKf5qHojRyvMvsIu-e9v-lEIgTA6-wuO_8ZbyjZ8eoTp9sJPCrstxPHMCe541H2Zbm7OfRM5xVsLqPHc/s400/Nominal_Earnings_Trend_Since_1980.png" alt="" id="BLOGGER_PHOTO_ID_5587697301413881362" border="0" /></a><br />This trend line shows the nominal earnings trend reaching the $90-$95 level around 2020. So current earnings and forward estimates are ten years ahead of "schedule"! This second graph seems to align with Shiller's suggestion of an S&P index of 1430 in 2020 (with a 15 valuation multiple, earnings would be $95).<br /><br />The key question for a stock market investor is what happens to that earnings line over the next decade: does it remain above trend line (not impossible, if you look at the late 1990s period), does it crater again as in 2008-2009, or does something else occur?<br /><br />This graph shows the extent to which nominal earnings can fall: a 35% fall from 1989-1991, a 54% fall from 2000-2001, and a 92% fall from 2007-2009 . So history shows that a falling numerator is not uncommon, i.e., reversion to mean not exclusively driven by a rising denominator. If falling earnings is a reasonably probable scenario, the next question is, when? With labor cost pressures low and held down by high unemployment, and rising commodities costs representing a possibly more manageable percentage of most cost structures, is a contraction in GDP the only thing that could meaningfully reduce earnings?<br /><br />Comments are welcome.<br /><img src="http://econviz.com/footer-1.gif?d=earnings201103" alt="" border="0" />hblhttp://www.blogger.com/profile/03192933210484147113noreply@blogger.com11tag:blogger.com,1999:blog-7861688742346636904.post-13809557854991985622011-02-17T15:38:00.000-05:002011-02-17T15:38:44.669-05:00Updated Macroeconomic Balance Sheet VisualizerAround a year ago, I wrote a <a href="http://www.thoughtofferings.com/2010/02/macroeconomic-balance-sheet-visualizer.html">blog post</a> about the draft copy of the <a href="http://econviz.com/balance-sheet-visualizer.html">macroeconomic balance sheet visualizer</a> I had set up, and got some useful feedback (thanks!)
