I'm no economist. But I've been reading Paul Krugman's blog for about 10 years now. And time after time his predictions about what would happen turned out to be true.<p>And most of his predictions were the exact opposite of the predictions that I was reading in the papers or I was hearing from the politicians. So, is it true that "other stuff" is relevant? Sure. But I'll take his economic insights - mistakes included - over all those other Nobel prize winning economists any day.
