676 days ago - As the United States’ worst housing market bust since the Great Depression raises the specter of a nasty recession, a serious reappraisal of Alan Greenspan’s 17-year chairmanship of the Federal Reserve is under way. Justified as this reappraisal might be, it should not be allowed to detract from Ben Bernanke’s role in today’s U.S. housing market debacle, especially since Mr. Bernanke assumed the Federal Reserve chairmanship in February 2006 a full year before the worst of the subprime lending excesses were to be made.
