Paul Krugman pauses to wonder why he’s been characterized as immoderate when — according to him — “there’s not a lot of air between my views and those of, say, staff economists at the Fed.” His conclusion: “What was radical, if you like, was my style, not my content.”
Bingo. Krugman’s detachment from mainstream economics is indeed a matter more of style than of content. But one symptom of that detachment is his failure to recognize that style is all that matters. Economics is most valuable not as a repository of received truths, but as a way of thinking — a way of thinking that has proved itself extraordinarily valuable as a bulwark against nonsense and claptrap. It’s that way of thinking — the style of economics — that Krugman so often and so depressingly abandons.
