Here's a good statement of the Keynesian view of recessions.
Excerpts:
"Our current economic discourse is pervaded by fatalism. Leave aside the people who insist that somehow Obama has destroyed capitalist incentives by passing Mitt Romney’s health care plan and threatening to raise tax rates to Clinton-era levels. Even among people who should be sensible, you hear many assertions that run something like this: historically, recovery from financial crisis is usually slow, so we have to accept a slow recovery this time around too. Actually, that’s more or less what Obama has been saying.
This fatalism is deeply destructive — because there’s no good reason we need to experience many years of high unemployment. What historical experience shows isn’t that there’s no answer to post-crisis slumps, it only shows that most governments have responded to such slumps with the same kind of fatalism and learned helplessness we’re showing now. (Hey, Greg, I have first dibs on that!)
We are not, after all, suffering from supply-side problems. We don’t have high unemployment because workers lack the necessary skills, or are stuck in the wrong industries or the wrong locations; the hypothesis that we’re mainly suffering structural unemployment has been repeatedly shot down by evidence. This is a demand-side slump; all we need to do is create more demand.
So why is this slump, like most slumps following financial crises, so protracted? Because the usual tools for pumping up demand have reached their limits. Normally we respond to demand-side slumps by cutting short-term nominal interest rates, which the Fed can move through open-market operations. But we now have severely depressed private demand thanks to the housing bust and the overhang of consumer debt, so even a zero rate isn’t low enough.
So what’s the right response? Should we just throw up our hands, and say that having 12 million or so adults who should be working out of work, and roughly $1 trillion per year of output we should be producing not getting produced, is just a fact of life? Or should we be using unconventional policies to deal with an abnormal situation?
The answer seems obvious. We should be using fiscal stimulus; we should be using unconventional monetary policy, including raising the inflation target; we should be pursuing aggressive measures to reduce mortgage debt. Not doing these things means accepting huge waste and hardship.
But, say the serious people, there are risks to doing any of these things. Well, life is full of risks. But it’s simply crazy to put a higher weight on the possibility that the invisible bond vigilantes might manifest themselves, or the inflation monster emerge from its secret cave, over the continuing reality of enormous human and economic damage from doing nothing.
The truth is that we have nothing to fear but fear itself — fear and complacency — the two things we have to fear are — amongst our fears ….
Anyway, seriously, the fatalism that has overtaken economic debate is a terrible thing. It is, indeed, the main enemy of prosperity.
