Idle labor, idle capital, perverse austerity

The great recession of 2008-09 has left us persistent high unemployment, record low interest rate, large corporate and bank reserves. Consumers are struggling to repair their balance sheets, yet neither governments nor large corporations are doing much to help solve the economic slump.

What's going on? Can "market" solve the problem on its own? And what do we mean by that, anyway?

The only sensible diagnosis I've seen so far by economists is that the "advanced world, accounting for 70 percent of world GDP at market prices, is in a liquidity trap."

What should be done?

In the words of Nobel Laureate Peter Diamond:

On the nation’s unemployment problem and how infrastructure spending could help solve it:

–Most of [the 9.1% unemployment rate], more than half of it, is inadequate aggregate demand and what we need now, very badly, is more fiscal stimulus and the continuation by the Fed of rolling out monetary stimulus as it fits their projections of what’s going on.

–Right now we have idle labor, idle capital… [and] interest rates are low, so doing it sooner has that advantage compared to doing it later. And third we do get a Keynesian multiplier out of it. –The fact that infrastructure spending will be phased in slowly doesn’t seem to me a shortcoming right now, because all the forecasts we’ve seen say coming out of this [malaise] is going to be a slow process.

Are we headed for another recession?

–There’s no question that we’re vulnerable….. It’s really important to put into place policies that would have the long-run effect of reducing debt growth. But there’s nothing on the debt side we need to do immediately. We do not have a debt crisis. We have a long-run debt problem and austerity today is perverse from the point of view of unemployment, and insofar as the economy is vulnerable that will make it more vulnerable, and of course a double-dip [recession] will lose us a lot of tax revenue.

Professor Diamond is known for his "search" model of labor market, which brings in a form of market friction to explain the lack of clearance in labor market. Even he thinks the unemployment problem is mostly an aggregate demand problem. The rest could perhaps be attributed to "structural" problems such as skill mismatch.
