The Oil Bubble Controversy, Revisited

One of the curious things about economic debate in the later Bush years was the conviction among many on the right that there wasn’t a bubble in housing, but that there was one in oil.

We now know the truth about housing. But what about oil?

Oil prices did spike to triple-digit levels in early 2008, then drop sharply. But think about the fact that right now, with the world economy still seriously depressed, oil is at $80 a barrel. This suggests to me that high oil prices are largely caused by fundamentals.

And it also suggests that resource constraints will be an issue if and when we do get a full recovery.
