LOL Cochran is saying is that he predicted he couldn't predict the financial crisis. LOL Well dang, even I could do that and I don't even need to hire a team of physicists to make me a pretty graph to prove it. Personally, I think Cochran's "efficient market" theory is based more on fairy tales than he cares to admit...or did he?
Cochran predicted he couldn't predict the financial meltdown, but a lot of people could; Robert Shiller, Raghuram Rajan, Kyle Bass, Brooksley Born just to name a few. But like Krugman more or less said, the "fresh water" economists had their "beauty" colored glasses on and so all they saw were the pretty charts and graphs convincing them that their "efficient market" hypothesis was "perfect" while totally ignoring the irrational human herd effect that occurred right before our very eyes for SIX YEARS and previously during the FIVE YEARS of the dot.com bubble. The "fresh water" economists only saw what they wanted to see. Imo, Cochran is a victim of the irrational herd mentality that Krugman referred to.
Another irrational herd effect is the culture of greed permeating Wall Street, IE: recent revelations of the systemic use of insider trading in hedge funds. So if the market is so "efficient" then why has it been relying on insider trading to set prices? That isn't how 'Say's Law' is supposed to work, is it? And why would any rational thinking person think that irrational home price increases would be sustainable when wages were stagnating and historical empirical evidence says otherwise? How naive can Cochran be? Well, judging by his short term thinking and the immaturity of his rebuttal, I'd say quite a lot.
Yeah, I'd say Krugman slayed Cochran. Score one for Keynesian economics. Not that I'm a Keynesian mind you, I'm just saying. Personally I see pros and cons in most economic theories but I also tend to think of economics in general as more like fortune telling than a science. Even a broken clock is right twice a day.
