Alan Greespan's memoir arrives with remarkable timing

--Alan Greenspan' memoir arrives with remarkable timing for two reasons. --One is that at a time like this, with financial markets in a upheaval, we yearn for guidance from the oracle who presided over 18 years of relative peace and prosperity in the U.S. economy. --the second is that a wave of revisionist thinking holds that the reign of Greespan may not have been so great after all, that bears some responsibility for the twin bubbles of dot-com mania and the recently deflated housing boom.
