Greenspan and the Bubble - New York Times: Most of what Alan Greenspan said at last week’s conference in his honor made very good sense. But his words of wisdom come too late. He’s like a man who suggests leaving the barn door ajar, and then - after the horse is gone - delivers a lecture on the importance of keeping your animals properly locked up.

Regular readers know that I have never forgiven the Federal Reserve chairman for his role in creating today’s budget deficit. In 2001 Mr. Greenspan, a stern fiscal taskmaster during the Clinton years, gave decisive support to the Bush administration’s irresponsible tax cuts, urging Congress to reduce the federal government’s revenue so that it wouldn’t pay off its debt too quickly. Since then, federal debt has soared. But as far as I can tell, Mr. Greenspan has never admitted that he gave Congress bad advice. He has, however, gone back to lecturing us about the evils of deficits.

Now, it seems, he’s playing a similar game with regard to the housing bubble. At the conference, Mr. Greenspan didn’t say in plain English that house prices are way out of line. But he never says things in plain English. What he did say, after emphasizing the recent economic importance of rising house prices, was that “this vast increase in the market value of asset claims is in part the indirect result of investors accepting lower compensation for risk. Such an increase in market value is too often viewed by market participants as structural and permanent.” And he warned that “history has not dealt kindly with the aftermath of protracted periods of low-risk premiums.” I believe that translates as “Beware the bursting bubble.”…

If Mr. Greenspan had said two years ago what he’s saying now, people might have borrowed less and bought more wisely. But he didn’t, and now it’s too late. There are signs that the housing market either has peaked already or soon will. And it will be up to Mr. Greenspan’s successor to manage the bubble’s aftermath.

How bad will that aftermath be? The U.S. economy is currently suffering from twin imbalances…. One way or another, the economy will eventually eliminate both imbalances. But if the process doesn’t go smoothly - if, in particular, the housing bubble bursts before the trade deficit shrinks - we’re going to have an economic slowdown, and possibly a recession…
