Paul Krugman: Why Economics Failed

Why didn't fiscal policy makers listen to economists?:

Why Economics Failed, by Paul Krugman, Commentary, NY Times: On Wednesday, I wrapped up the class I’ve been teaching..: “The Great Recession: Causes and Consequences.” ...I found myself turning at the end to an agonizing question: Why, at the moment it was most needed and could have done the most good, did economics fail?
I don’t mean that economics was useless to policy makers. ... While ... few economists saw the crisis coming..., since the fall of Lehman Brothers, basic textbook macroeconomics has performed very well. ...
In what sense did economics work well? Economists who took their own textbooks seriously quickly diagnosed the nature of our economic malaise: We were suffering from inadequate demand ... and a depressed economy. ...
And the diagnosis ... had clear policy implications: ...this was no time to worry about budget deficits and cut spending... We needed more government spending, not less, to fill the hole left by inadequate private demand. But... Since 2010, we’ve seen a sharp decline in discretionary spending and an unprecedented decline in budget deficits, and the result has been anemic growth and long-term unemployment on a scale not seen since the 1930s.
So why didn’t we use the economic knowledge we had?
One answer is that most people find the logic of policy in a depressed economy counterintuitive. ... And even supposedly well-informed people balk at the notion that simple lack of demand can wreak so much havoc. Surely, they insist, we must have deep structural problems, like a work force that lacks the right skills; that sounds serious and wise, even though all the evidence says that it’s completely untrue.
Meanwhile, powerful political factions ... whose real goal is dismantling the social safety net have found promoting deficit panic an effective way to push their agenda. And such people have been aided and abetted by what I’ve come to think of as the trahison des nerds — the willingness of some economists to come up with analyses that tell powerful people what they want to hear, whether it’s that slashing government spending is actually expansionary, because of confidence, or that government debt somehow has dire effects on economic growth even if interest rates stay low.
Whatever the reasons basic economics got tossed aside, the result has been tragic. ... We have, all along, had the knowledge and the tools to restore full employment. But policy makers just keep finding reasons not to do the right thing.
