Even When Krugman’s Right, He’s Wrong

Prashanth Perumal insisted that I comment on this Krugman blog post from January. The reason I didn’t comment on it at the time was that my views here are rather nuanced. It’s one of those tricky situations where I agree with Krugman that his opponents are wrong, but I deny that Krugman is therefore right. In other words, Krugman’s enemies–Eugene Fama and John Cochrane–use invalid arguments but reach a true conclusion, namely that big government deficits don’t help an economy in recession.
