Krugman and the rest of the family

I simply can’t let Krugman … get away with writing off a large part of contemporary economic discourse (not to mention of the history of economic thought) and with his declaration that Larry Summers has “laid down what amounts to a very radical manifesto” (not to mention the fact that I was forced to waste the better part of a quarter of an hour this morning listening to Summers’s talk in honor of Stanley Fischer at the IMF Economic Forum, during which he announces that he’s finally discovered the possibility that the current level of economic stagnation may persist for some time).

Krugman may want to curse Summers out of professional jealousy. Me, I want to curse the lot of them—not only the MIT family but mainstream economists generally—for their utter cluelessness when it comes to making sense of (and maybe, eventually, actually doing something about) the current crises of capitalism.

So, what is he up to? Basically, Krugman showers Summers in lavish praise for his belated, warmed-over, and barely intelligible argument that attains what little virtue it has about the economic challenges we face right now by vaguely resembling the most rudimentary aspects of what people who read and build on the ideas of Marx, Kalecki, Minsky, and others have been saying and writing for years. The once-and-former-failed candidate for head of the Federal Reserve begins with the usual mainstream conceit that they successfully solved the global financial crash of 2008 and that current economic events bear no resemblance to the First Great Depression. But then reality sinks in: since in their models the real interest-rate consistent with full employment is currently negative (and therefore traditional monetary policy doesn’t amount to much more than pushing on a string), we may be in for a rough ride (with high output gaps and persistent unemployment) for some unknown period of time. And, finally, an admission that the conditions for this “secular stagnation” may actually have characterized the years of bubble and bust leading up to the crisis of 2007-08.

That’s where Krugman chimes in, basking in the glow of his praise for Summers, expressing for the umpteenth time the confidence that his simple Keynesian model of the liquidity trap and zero lower bound has been vindicated. The problem is, Summers can’t even give Alvin Hansen, the first American economist to explicate and domesticate Keynes’s ideas, and the one who first came up with the idea of secular stagnation based on the Bastard Keynesian IS-LM model, his due … I guess it’s simply too much to expect they actually recognize, read, and learn from other traditions within economics …

And things only go down from there. Because the best Summers and Krugman can do by way of attempting to explain the possibility of secular stagnation is not to analyze the problems embedded in and created by existing economic institutions but, instead, to invoke that traditional deus ex machina, demography.

“Now look forward. The Census projects that the population aged 18 to 64 will grow at an annual rate of only 0.2 percent between 2015 and 2025. Unless labor force participation not only stops declining but starts rising rapidly again, this means a slower-growth economy, and thanks to the accelerator effect, lower investment demand.”

You would think that a decent economist, not even a particularly left-wing one, might be able to imagine the possibility that a labor shortage might cause higher real wages, which might have myriad other effects, many of them really, really good—not only for people who continue to be forced to have the freedom to sell their ability to work but also for their families, their neighbors, and for lots of other participants in the economy. But, apparently, stagnant wages (never mind supply-and-demand) are just as “natural” as Wicksell’s natural interest rate …

It is no wonder, then, that mainstream economists—even the best of them—are so painfully inarticulate and hamstrung when it comes to making sense of the current economic malaise.

I’ll admit, it wouldn’t be so bad if it was just a matter of professional jealousy and their not being able to analyze what is going on except through the workings of a small number of familiar assumptions and models. They talk as if it’s only their academic reputations that are on the line. But we can’t forget there are millions and millions of people, young and old, in the United States and around the world, whose lives hang in the balance—well-intentioned and hard-working people who are being made to pay the costs of economists like Krugman attempting to keep things all in the family.
