Paul Krugman has a very good, if scary column for Monday's New York Times. Here's the money quote:
The current U.S. financial crisis bears a strong resemblance to the crisis that hit Japan at the end of the 1980s, and led to a decade-long slump that worried many American economists, including both Mr. Bernanke and yours truly. We wondered whether the same thing could take place here — and economists at the Fed devised strategies that were supposed to prevent that from happening. Above all, the response to a Japan-type financial crisis was supposed to involve a very aggressive combination of interest-rate cuts and fiscal stimulus, designed to prevent the crisis from spilling over into a major slump in the real economy.
Why does Krugman think we're "turning Japanese"? More on the flip.
