A paper by economist James Hamilton at the Brooking Institution argues that it was the oil shock that served as the catalyst for our recession:
The grand retelling goes something like this. Cheap gasoline from the 1990s into this decade encouraged families to set up their homes farther from the cities where they worked. But as the price of gas began to increase, it put a big strain of these families' commutes. With gas rising from $2 to $4, the price of these long drives doubled, straining those families' most expensive payments, namely: mortgages. When families realized they could not afford their exurban commutes, they sold their homes for a big loss. Voila: Their mortgage crisis became a bank crisis and the rest is our living history.
Notably, Hamilton himself has a tough time believing the theory. But his numbers don't lie. My reaction is similar: Huh? Are we really to believe that this whole thing was caused by oil shocks? What about real estate, subprime mortgages, credit default swaps and over leveraging? Well, I'm inclined to say that this report doesn't actually change much. The crisis was caused by a culmination of events resulting in a perfect storm. Not only were gas prices on the rise through last summer but commodities across the board were spiraling upward. Eventually the entire system seized up and the housing bubble popped, triggering a cascade of bad investments that broke the credit system.
So I don't think it was distinctly oil's fault. But it didn't help. And in turn this might be a better way of thinking about the recession because it concludes with an argument for energy independance. All roads lead there.
