Economists wrong? No, you're kidding!

Doubling Down

Paul Krugman, NYT

Brad DeLong is not happy with some of his fellow intellectuals:

Those who said that there would be no downturn, or that recovery would be rapid, or that the economy’s real problems were structural, or that supporting the economy would produce inflation (or high short-term interest rates), or that immediate fiscal austerity would be expansionary were wrong. Not just a little wrong. Completely wrong. 

Of course, we historically-minded economists are not surprised that they were wrong. We are, however, surprised at how few of them have marked their beliefs to market in any sense. On the contrary, many of them, their reputations under water, have doubled down on those beliefs, apparently in the hope that events will, for once, break their way, and that people might thus be induced to forget their abysmal forecasting track record.
