"After months of calling for inflation of housing prices, Krugman in 2002 came right out and said the Fed needed to create a housing bubble. Since 2007, Krugman has repeatedly and angrily denied that was what he was saying, so let me run his comments in their full context: A few months ago the vast majority of business economists mocked concerns about a "double dip," a second leg to the downturn. But there were a few dogged iconoclasts out there, most notably Stephen Roach at Morgan Stanley. As I've repeatedly said in this column, the arguments of the double-dippers made a lot of sense. And their story now looks more plausible than ever. The basic point is that the recession of 2001 wasn't a typical postwar slump, brought on when an inflation-fighting Fed raises interest rates and easily ended by a snapback in housing and consumer spending when the Fed brings rates back down again. This was a prewar-style recession, a morning after brought on by irrational exuberance. To fight this recession the Fed needs more than a snapback; it needs soaring household spending to offset moribund business investment. And to do that, as Paul McCulley of Pimco put it, Alan Greenspan needs to create a housing bubble to replace the Nasdaq bubble.6 Well, Krugman got exactly what he wanted."
