Ben Polak and Peter K. Schott make a compelling argument in the New York Times that this recession differs from the preceding two downturns because of under-employment by state and local governments:
Without this hidden austerity program, the economy would look very different. If state and local governments had followed the pattern of the previous two recessions, they would have added 1.4 million to 1.9 million jobs and overall unemployment would be 7.0 to 7.3 percent instead of 8.2 percent.
Why is this happening? One possibility is that we are witnessing a secular change in state and local politics, with voters no longer willing to pay for an ever-larger work force. An alternative explanation is that even though many state and local governments are constrained not to run deficits, they can muddle through a standard recession without cutting jobs. But when hit by a huge recession like that of 1981 or the latest one, the usual mix of creative accounting and shifting in capital expenditures cannot absorb the shock, and jobs have to go.
