Why Austerity Doesn't Work
From Krugman:
For the past two years most policy makers in Europe and many politicians and pundits in America have been in thrall to a destructive economic doctrine. According to this doctrine, governments should respond to a severely depressed economy not the way the textbooks say they should by spending more to offset falling private demand but with fiscal austerity, slashing spending in an effort to balance their budgets.
Critics warned from the beginning that austerity in the face of depression would only make that depression worse. But the austerians insisted that the reverse would happen. Why? Confidence! Confidence-inspiring policies will foster and not hamper economic recovery, declared Jean-Claude Trichet, the former president of the European Central Bank a claim echoed by Republicans in Congress here. Or as I put it way back when, the idea was that the confidence fairy would come in and reward policy makers for their fiscal virtue.
The good news is that many influential people are finally admitting that the confidence fairy was a myth. The bad news is that despite this admission there seems to be little prospect of a near-term course change either in Europe or here in America, where we never fully embraced the doctrine, but have, nonetheless, had de facto austerity in the form of huge spending and employment cuts at the state and local level.
...
None of this should come as news, since the failure of austerity policies to deliver as promised has long been obvious. Yet European leaders spent years in denial, insisting that their policies would start working any day now, and celebrating supposed triumphs on the flimsiest of evidence. Notably, the long-suffering (literally) Irish have been hailed as a success story not once but twice, in early 2010 and again in the fall of 2011. Each time the supposed success turned out to be a mirage; three years into its austerity program, Ireland has yet to show any sign of real recovery from a slump that has driven the unemployment rate to almost 15 percent
