An interview of NYU's Nouriel Roubini, aka Dr Doom, in WSJ, more here.
Here are the best bits:
What exactly is Nouriel Roubini's economic philosophy? "I believe in market economics," he says, with some emphasis. "But to paraphrase Churchill -- who said this about democracy and political regimes -- a market economy might be the worst economic regime available, apart from the alternatives.
"I believe that people react to incentives, that incentives matter, and that prices reflect the way things should be allocated. But I also believe that market economies sometimes have market failures, and when these occur, there's a role for prudential -- not excessive -- regulation of the financial system. The two things that Greenspan got totally wrong were his beliefs that, one, markets self-regulate, and two, that there's no market failure."
How could Mr. Greenspan have been so naïve, I ask, hoping to get a rise. "Well," says Mr. Roubini, "at some level it's good to have a framework to think about the world, in which you emphasize the role of incentives and market economics . . . fair enough! But I think it led to an excessive ideological belief that there are no market failures, and no issues of distortions on incentives. Also, central banks were created to provide financial stability. Greenspan forgot this, and that was a mistake. I think there were ideological blinders, taking Ayn Rand's view of the world to an extreme.
