Is there something fundamentally broken in the heart of our economy?

SHOOT: Answer - yes. Suburbia. It's broken because it required cheap energy to run it. Can we fix it? Only if we redesign our living arrangements, to something more walkable and less dependent on cars.

"I don't think," Summers told the Peterson Institute crowd - deviating again from his text - "that anyone fully understands this phenomenon." And that raises some worrying questions. Will creating jobs be that much slower too? Will double-digit unemployment persist even after we emerge from this recession? Has the idea of full employment rather suddenly become antiquated? Is there something fundamentally broken in the heart of our economy? And if so, how can we fix it?

clipped from news.yahoo.com There appears to be, Summers told the suddenly very attentive crowd, a strange bit of physics working itself out in our economy. The problem is related to a hiccup in an economic rule called Okun's law. First mooted by economist Arthur Okun in 1962, the law (it's really more of a rule of thumb) says that when the economy grows, it produces jobs at a predictable rate, and when it shrinks, it sheds them at a similarly regular pace. It's a labor version of how the accelerator on your car works: add gas, go faster; less gas, go slower. What made Summers' frank comment important is that it suggests this just-add-gas relationship may now be malfunctioning. The American economy has been shedding jobs much, much faster than Okun's law predicts. According to that rough rule, we should be at about 8.5% unemployment today, not slipping toward 10%. Something new and possibly strange seems to be happening in this recession. Something unpredicted by the experts.
