Positive Feedback, for a change

Nattering nabobs of negativity? Nyet! Instead of finding further fault with economists who I disagree with, let me share some interesting articles from economists who I agree with.

First, Jim Hamilton reports on a beautifully simple test for inflation: the rolling correlations between various commodity prices. It turns out that these correlations have increased quite significantly in recent months and years. This is strong suggestive evidence that there is a common factor driving all prices higher. What could that factor be? Hmm, I wonder.

Second, Steve Waldman has a great post on the role of morality in economics. Is there such a role? He says yes: “The thing is, human affairs are a morality play, and economics, if it is to be useful at all, must be an account of human affairs”. I couldn’t agree more. There’s a follow-up post here.

Third, Raghu Rajan has two policy suggestions that are exactly the same as my own: “The US should dial back its aggressive monetary policy, focusing on repairing its own economy’s structural problems, while emerging markets should respond by allowing their exchange rates to appreciate steadily, thereby facilitating the growth of domestic demand.”
