A Manifesto for Economic Sense, Paul Krugman, Princeton University, and Richard Layard, LSE Centre for Economic Performance
“More than four years after the financial crisis began, the world’s major advanced economies remain deeply depressed, in a scene all too reminiscent of the 1930s. And the reason is simple: we are relying on the same ideas that governed policy in the 1930s. These ideas, long since disproved, involve profound errors both about the causes of the crisis, its nature, and the appropriate response.
“These errors have taken deep root in public consciousness and provide the public support for the excessive austerity of current fiscal policies in many countries…”
The Perils of Prophecy, J. Bradford DeLong, University of California at Berkely, June 27, 2012:
…Indeed, we understood that monetarist cures were likely to prove insufficient; that sovereigns need to guarantee each others’ solvency; and that withdrawing support too soon implied enormous dangers. We knew that premature attempts to achieve long-term fiscal balance would worsen the short-term crisis – and thus be counterproductive in the long-run. And we understood that we faced the threat of a jobless recovery, owing to cyclical factors, rather than to structural changes.
On all of these issues, historically-minded economists were right. 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…
