Now, Krugman claims that Schumpeter was long ago discredited, but this passage is not totally crazy. Schumpeter is telling us that caution in policymaking can be appropriate. We can do more harm than good by intervening to slow down adjustments that will have to occur in any event, and sometimes allowing events to take their course can be the best strategy. Clearly, this need not always be the case, but as a general principle, it's hard to argue with it.
Schumpeter also states, presumably also as a general principle, that "the trouble is not fundamentally with money and credit," and that I would argue with. Obviously, we don't have to look any further than the recent recession to find an episode where money and credit seem to have been important elements in what was going on. However, one could make a case that what currently ails the US economy - principally dismal performance in the labor market - has little to do with money and credit, and monetary invention will do little, if anything, to cure the problem, whatever it is. There is a lot we do not know of course, and there may be something going on that we do not understand about how financial ailments interact with labor market ailments. Who knows?
Now, the funny part of Krugman's piece is the conclusion:
But here we are, in 2010 — and something very much like that position is being forcefully advocated by Wolfgang Schauble, the government of China, Narayanan Kocherlakota, and Sarah Palin.Now, I'm assuming that what Krugman has in mind here is that all of these people (or organizations) have in common a distaste for QE2. However much Narayana may enjoy the company of these other individuals (maybe he and Sarah might enjoy a good game of table hockey), I don't think he belongs in that group. Kocherlakota's latest posted speech is this one. In it, he discusses some policy options, and his conclusion is this:
I’ve talked about three possible tools—lowering the IOER, strengthening the forward guidance in the FOMC statement, and quantitative easing. As I mentioned earlier, Chairman Bernanke observed in his August 27 speech that each of these tools has benefits and drawbacks that must be balanced against each other. With QE, I would say that the multiple novel effects make the calculus even more difficult than usual.Before coming to that conclusion, he has some thoughtful things to say about quantitative easing and its possible effects, using available economic theory, and framing the debate in terms a lay audience should be able to understand. Basically, he's saying that we have some theory and empirical work to bring to bear in understanding what QE might do, but there is an awful lot that we do not know. There's not much in there to disagree with, and it's far from Dark-Ages economics.
