Must- and Should-Reads:

Simon Wren-Lewis: “The IMF… may be full of economists, but it is ultimately run by politicians who may have too many ties to those in the Eurozone. But as Ashoka Mody says, the IMF’s credibility is at stake. It should… focus its efforts on getting the rest of the Troika to be realistic. Above all else, Greece must be helped out of its depression…. Sensible macroeconomists, including those at the IMF, know that makes sense. If Yanis Varoufakis could not achieve this, perhaps the economists at the IMF can do better…”

Rent-Seeking, Price-Taking Competition, Paul Romer, and the History of Economic Thought

Mark Thoma directs us to Paul Romer. And Paul Romer gets remarkably exercised about George Stigler’s long and successful war against the use of the theory of monopolistic competition in economics, with its consequence that even today we have “scientifically unacceptable” people who say:

We will never, as a matter of principle, consider a model in which there are ever any monopolies. We will dogmatically stick only to models of price-taking competition…

From my perspective it is not the contemporary implications of this train of thought for growth theory that are important–for as best I can tell there are people who write growth models where every market has price-taking competition but there is nobody outside who reads them–but rather the historical implications of this train of thought for industrial organization, antitrust, and the rise of the rent seeking sector in the American economy.

I eagerly want to read and hope to see more work in this area.

And there is something to be written about people who employ arguments based on ideological triggers. For them, certain arguments have force only when they lead to ideologically-convenient conclusions. We see this perhaps most strikingly in the Neoconservatives. Their core argument that government needs to be cautious, hesitant, and to focus on nudges rather than commands because (a) implementation is very hard, and general equilibrium effects are (b) often very large and (c) always very hard to predict. But, somehow, this argument applies only when the government is attempting to secure the natural rights of African-Americans, or women, or homosexuals. When the government is trying to stomp Commies or Arabs then, by contrast, they gravitate to arguments for an aggressive forward policy to secure “democracy”. Max Weber dealt with such people in his day: His line was: “the materialist interpretation of history is not a streetcar that one can get off of anywhere one likes.“

And, yes, all of what I call “Chicago Economics” does seem to be like that today–although very little of it was back in the 1930s…

Via Mark Thoma, Paul Romer:

Paul Romer: Urbanization, Charter Cities and Growth Theory: “To be honest, I think that a substantial fraction of the work that people are now doing on growth…

…has to be judged a failure from a scientific perspective. In particular–and I apologize if this relies too much on the jargon of our field–monopolistic competition turns out to be just the tool for understanding…. (It also turns out to be the tool for understanding international trade, economic geography, and macroeconomics.) But there has been a series of models that are associated with the University of Chicago–from what some people call the freshwater camp in macroeconomics–that are continuing a fight that George Stigler started in the 1930s to keep monopolistic competition from being used in economics. It is hard to explain to an outsider why a whole group of economists have ended up on the wrong side of scientific progress, resisting the direction that all of modern economic theory is taking, but they are.

In the economics of ideas, we have to be willing to at least consider the possibility that someone could have some control over an idea, hence some monopoly power associated with ideas. This could come from patent or a copyright. It could also come from secrecy. Then we can ask if it is a good idea or a bad idea to have more intellectual property rights or more protection of ownership of ideas. We know that the answer here is mixed. Sometimes some amount of it can be good, but it can also be harmful if the property rights are too strong or are given to the wrong types of ideas. But if you don’t even allow for the possibility of ex post monopoly rents from the discovery of ideas, you can’t even ask the question.

So it is scientifically unacceptable to have people who say:

We will never, as a matter of principle, consider a model in which there are ever any monopolies. We will dogmatically stick only to models of price-taking competition.

I think this an untenable scientific stance. I don’t think that this critique is going to reignite interest in growth theory. But like I said, when it’s time for interest to come back, somebody have a new take on growth theory, and work in this area will start again. But in the meantime, we have to stop tolerating work that is scientifically unjustifiable.

Must-Read: Olivier Coibion et al.: How Do Firms Form Their Expectations? New Survey Evidence

Must-Read: Yes, “anchoring” and “extrapolative” rational-inattention (and non-rational-inattention) models do much better in explaining expectations than do rational expectations models. Why do you ask?

Olivier Coibion et al: How Do Firms Form Their Expectations? New Survey Evidence: “We implement a new survey of firms’ macroeconomic beliefs in New Zealand…

…and document a number of novel stylized facts from this survey. Despite nearly twenty-five years under an inflation targeting regime, there is widespread dispersion in firms’ beliefs about both past and future macroeconomic conditions, especially inflation, with average beliefs about recent and past inflation being much higher than those of professional forecasters. Much of the dispersion in beliefs can be explained by firms’ incentives to collect and process information, i.e. rational inattention motives. Using experimental methods, we find that firms update their beliefs in a Bayesian manner when presented with new information about the economy. But few firms seem to think that inflation is important to their business decisions and therefore they tend to devote few resources to collecting and processing information about inflation.

Weak wage growth continues apace

The U.S. economy added 223,000 jobs in April, after downward revisions brought the prior month to only 85,000 jobs. Over the last three months the economy has on average added about 191,000 jobs. At the same time, wages in the private sector grew in April by 2.2 percent over the last year, far below what is typically considered healthy nominal wage growth.

For workers to maintain or increase their share of income, nominal wages must grow at an annual rate of at least 3.5 percent, assuming the Federal Reserve’s inflation target of 2.0 percent and annual productivity growth of 1.5 percent. In contrast, nominal wages grew by 2.2 percent over the last year and at an annual rate of 2.3 percent over the last three months. Looking at the last three months is typically a way to understand recent trends without being tricked by month to month fluctuations. Last month’s acceleration in the three-month rate, to 2.7 percent, however appears more like noise than an encouraging trend.

Wage growth continues to stagnate for production and non-supervisory workers. Since January wage growth for this group of workers, who comprise about four-fifths of private sector employment, has consistently been below the rate of wage growth for all workers, suggesting a contribution to increasing wage inequality. Nominal production wages grew by only 1.9 percent in April, compared to last year.

Nevertheless wages appear to be growing at healthier rates in the leisure and hospitality sector, which includes restaurants, where annual wage growth was 4.0 percent over the last three months. During that time period wages in the construction industry grew at an annual rate of about 3.7 percent. Financial sector wages grew at 2.6 percent during the last three months, above the 2.3 percent average for the overall private sector.

Essentially no sector performed exceptionally well last month in creating jobs. Professional and business services added about 62,000 jobs. Construction added 45,000 jobs, but this sector also lost jobs in March, so that over the last two months it only added 36,000 jobs. Manufacturing employment remained essentially unchanged, as one would expect given the recent increase in the trade deficit.

The employed share of the population ages 25 through 54 remained at 77.2 percent in April, basically unchanged since an uptick in January of this year. This is not encouraging news for wage growth. Although there are many signals for labor market tightness, a key indicator is the prime-age employment-to-population ratio. When employment rates are higher, employers are compelled to raise wages in order to attract and retain workers.

During the last twenty five years, nominal wage growth has only sustainably exceeded a target of 3.5 percent when the prime-age employment-to-population ratio was at least 79 percent, substantially above the current employment rate.  The employed share of the prime-age population grew by nearly one percentage point in 2014, but currently growth seems to have slowed to about 0.7 over the past year to 0.8 percentage points during the past three months. As a result, we should not expect to see the employment-to-population ratio exceed 79.0 percent until more than two years from now, sometime in mid-2017. And only then can we expect to see healthy nominal wage growth.

With no substantial acceleration of wage growth, there is still significant slack in the US labor market. A 5.4 percent unemployment rate with weak wage growth suggests that there either is a large reserve of potential workers not yet in the labor force, or that the unemployment rate can fall substantially below economists’ usual targets of an unemployment rate consistent with a tight labor market without sparking wage inflation.

Optimal Control, Fiscal Austerity, and Monetary Policy

I find myself perseverating over the awful macroeconomic policy record of the Conservative-Liberal Democrat government of the past five years in Britain, and the unconvincing excuses of those who claim that the austerity policies it implemented were not a disaster–and that the austerity policies it ran on would not have come close to or actually broken the back of the economy.

Leaving to one side the fact that it is ludicrous that a depression that originates in overbuilding in the desert between Los Angeles and Albuquerque and overleverage in New York has a larger impact shock on the UK than on the US:

I am still looking for an explanation of why a UK that was growing as fast as the US in the 2000s before 2008 has been growing since–other than that the greater fiscal austerity (and less pressure from the government for monetary expansion) actually had the same effects on output in a Britain that was at the ZLB as it has had everywhere else:

Graph Gross Domestic Product by Expenditure in Constant Prices Total Gross Domestic Product for the United Kingdom© FRED St Louis Fed

The point that elementary optimal-control considerations mandate that the economy be far from the zero lower bound on safe nominal interest rates before you even begin to think about removing rather than increasing fiscal expansion. As long as the nominal interest rates on long term government debt are very low–as long as monetary policy has shot its interest-rate bolt and is expected remain in that posture for a considerable time–there may be benefits to credibly promising future austerity, but undertaking present austerity simply cannot be the best policy.

Yet a great many people in Britain do not seem to understand this. Even the very smart Tony Yates does not seem to understand this:

Simon Wren-Lewis: Reply to Tony Yates: “Tony… has a problem with… [my] first…

…which was about the 2010 ‘crisis’. So his ‘third way’ is really 7/8th my way!… [On] the 2010 crisis. Tony agrees that there were no signs of a crisis in the markets…. [Note] there is rather a big difference between “we saved the economy from a firestorm”, and “we took prudent action because bad things might have happened”. So maybe 15/16th my way. As there was no actual crisis, what were the chances of one happening? Eric Lonergan… makes an additional point… I can too easily forget. Because austerity damages the real economy, it increases domestic credit risks… [and] actually increase government default risk…. Austerity as a precautionary policy can actually make the outcome you are trying to prevent more likely….

If markets had suddenly taken fright on the deficit and stopped buying UK debt… the Bank could have just bought the debt…. Could it control inflation at the same time?… [Yes] if you are at the Zero Lower Bound (ZLB)…. Paul Krugman has written a paper on this, but it becomes irrelevant because of our second disagreement…. Tony sees the MPC as… succeeding… in… balance[ing] between inflation being too high and output being too low. If that is the case, the ZLB was not actually a constraint….

You wait until you are well clear of the Zero Lower Bound (ZLB) before embarking on fiscal tightening. You are about to hit the economy hard, so you want to be pretty sure that someone else will be able to make sure it can absorb that blow. In the case of Osborne in June 2010, we do not know if he even understood the risk…. Tony’s argument about inflation is not an excuse for austerity, but an argument about how much in practice it cost…. 2010 austerity was a first order policy mistake, because it took unnecessary and large risks with the economy…

In retrospect, monetarists–even conservative monetarists–would have been much better off, and all of us would have been much better off, if Social Credit politicians had won in the 1930s, and if “monetary policy” took the form of equal-dollar credits to everyone with a Social Security number, rather than open-market operations aimed at making “bank rate” effective. The Chair of the Federal Reserve or the Governor of the Bank of England could then, every month, announce what the national monthly monetary dividend would be and provide forward guidance as appropriate. And there would be none of this, from Tony Yates: “We cannot use the demand-management tools that would be effective! We need to cut the deficit in a depression and so do first-order harm to the economy because the second-order benefits of not scaring away the Confidence Fairy are surely larger!”

Must-Read: Chris Blattman: The Wire Got It Backwards

Morning Must-Read: Chris Blattman: The Wire Got It Backwards: “This article by Emily Badger in WashPo doesn’t say it outright…

…but for lower class black Americans, this country basically looks like a failed state. Some books and articles I recommend: Vesla Weaver’s book, Arrested Citizenship, or her shorter Boston Review article on the criminal justice system. Alice Goffman’s amazing ethnography of a Philadelphia neighborhood, On The Run. Jill Leovy’s Ghettoside, on murder and policing in Watts LA. Mark Kleiman’s When Brute Force Fails, on the behavioral perversities of criminal justice. The Harper High School episodes of This American life. With one exception, these have all been written by white people. And I would bet all fall in the category of reading The New Yorker and find Starbucks lowbrow. While I am myself in that category (well, I’m actually sick of The New Yorker) I would appreciate pointers to the best of the best books and essays by another race and class.

The Problems with Our Press Corps Run Deep: Eugene Stern Explains That Nick Kristof of the New York Times Is Not Smarter than an 8th Grader

Much of the dysfunction of the American press corps is driven by the ideological commitments of its bosses, the cultural flaws of its journalists’ communities, or the desperate need to scare its readers and viewers and thus keep them reading and viewing so that their eyeballs can be sold to advertisers.

Some of the dysfunction is not. Some of the dysfunction is unmotivated and completely pointless, even on its own terms.

Here we have Eugene Stern warning readers that reading Nick Kristof of The New York Times will not make you better informed:

Eugene Stern: Nick Kristof is not Smarter than an 8th Grader: “Jordan Ellenberg pointed me to this blog post…

…which highlights the problem…. In spite of Kristof’s alarmism, it turns out that American eighth graders actually did quite well on the 2011 TIMSS…. Out of 42 countries tested, the US placed 9th. If you look at the scores by country, you’ll see a large gap between the top 5 (Korea, Singapore, Taiwan, Hong Kong, and Japan) and everyone else. After that gap comes Russia, in 6th place, then another gap, then a group of 9 closely bunched countries… [including] the US…. Our performance isn’t mind-blowing, but it’s not terrible either. So what the hell is Kristof talking about?…

In a list of 88 publicly-released questions… the US placed in the top third… on 45… the middle third on 39, and the bottom third on 4…. US kids did particularly well on statistics, data interpretation, and estimation… For example, 80% of US eighth graders answered this question correctly:

Which of these is the best estimate of (7.21 × 3.86) / 10.09?

(A) (7 × 3) / 10   (B) (7 × 4) / 10   (C) (7 × 3) / 11   (D) (7 × 4) / 11

More American kids knew that the correct answer was (B) than Russians, Finns, Japanese, English, or Israelis. Nice job, kids! And let’s give your teachers some credit too!

But Kristof… has a narrative of American underperformance in mind, and if the overall test results don’t fit his story, he’ll just go and find some results that do!… Kristof literally went and picked the two questions out of 88 on which the US did the worst, and highlighted those in the column. (He gives a third example too, a question in which the US was in the middle of the pack, but the pack did poorly, so the US’s absolute score looks bad.) And, presto!–instead of a story about kids learning stuff and doing decently on a test, we have yet another hysterical screed about Americans “struggling to compete with citizens of other countries.”

Kristof gives no suggestions for what we can actually do better, by the way. But he does offer this helpful advice:

Numeracy isn’t a sign of geekiness, but a basic requirement for intelligent discussions of public policy. Without it, politicians routinely get away with using statistics, as Mark Twain supposedly observed, the way a drunk uses a lamppost: for support rather than illumination.

So do op-ed columnists, apparently.

I really do not know what kind of bad actor Kristof is here. Did he decide to misrepresent the study on his own? Was he fed a set of notes for his column from some lobbyist who misrepresented the study to him, and failed to check whether what he was being told was accurate? I would like to know…
