Paul Krugman, Gattopardo Economist

In response to Thomas Palley’s op-ed, Paul Krugman has written a couple of pieces on his New York Times blog (here and here)

I have seen many heteredox economists defending Krugman but these pieces should now make it crystal clear that Paul Krugman himself is the head of Gattopardo Economics. Consciously or subconsciously, Krugman’s strategy has been to sideline heteredox, in the hope that pages of history sing praises of him. Unfortunately for him, whenever he gets into a technical argument with heteredox economists on money, he makes the silliest mistakes.

Rather than giving many examples of why Krugman is the part of the problem, let me illustrate one example where he pushed very hard on the issue of free trade. It is a lecture paper for Manchester conference on free trade, March 1996 titled Ricardo’s Difficult Idea.

The following quote is clearly a strategy for propaganda:

5. What can be done?

I cannot offer any grand strategy for dealing with the aversion of intellectuals to Ricardo’s difficult idea. No matter what economists do, we can be sure that ten years from now the talk shows and the op-ed pages will still be full of men and women who regard themselves as experts on the global economy, but do not know or want to know about comparative advantage. Still, the diagnosis I have offered here provides some tactical hints:

(i) Take ignorance seriously: I am convinced that many economists, when they try to argue in favor of free trade, make the mistake of overestimating both their opponents and their audience. They cannot believe that famous intellectuals who write and speak often about world trade could be entirely ignorant of the most basic ideas. But they are — and so are their readers. This makes the task of explaining the benefits of trade harder — but it also means that it is remarkably easy to make fools of your opponents, catching them in elementary errors of logic and fact. This is playing dirty, and I advocate it strongly.

(ii) Adopt the stance of rebel: There is nothing that plays worse in our culture than seeming to be the stodgy defender of old ideas, no matter how true those ideas may be. Luckily, at this point the orthodoxy of the academic economists is very much a minority position among intellectuals in general; one can seem to be a courageous maverick, boldly challenging the powers that be, by reciting the contents of a standard textbook. It has worked for me!

(iii) Don’t take simple things for granted: It is crucial, when trying to communicate Ricardo’s idea to a broader audience, to stop and try to put yourself in the position of someone who does not know economics. Arguments must be built from the ground up — don’t assume that people understand why it is reasonable to assume constant employment, or a self-correcting trade balance, or even that similar workers tend to be paid similar wages in different industries.

(iv) Justify modeling: Do not presume, as I did, that people accept and understand the idea that models facilitate understanding. Most intellectuals don’t accept that idea, and must be persuaded or at least put on notice that it is an issue. It is particularly useful to have some clear examples of how “common sense” can be misleading, and a simple model can clarify matters immensely. (My recent favorite involves the “dollarization” of Russia. It is not easy to convince a non-economist that when gangsters hoard $100 bills in Vladivostock, this is a capital outflow from Russia’s point of view — and that it has the same effects on the US economy as if that money was put in a New York bank. But if you can get the point across, you have also taught an object lesson in why economists who think in terms of models have an advantage over people who do economics by catch-phrase). None of this is going to be easy. Ricardo’s idea is truly, madly, deeply difficult. But it is also utterly true, immensely sophisticated — and extremely relevant to the modern world.
