The New York Times reports that Japan's decade-long economic slump following the bursting of its 1980s economic bubble offers important lessons for the U.S. Of these, the most important one seems to be that banks and others exposed to bad loans should write them off fast and move on. It was Japan's unwillingness to bite the bullet that kept it stuck for a decade.

Last month, I compared Japan's negative interest rates to the ones we have now. But what caused the predicament that led Japan to cut its rates so much? In Japan, housing prices in the major metropolitan regions nearly tripled from 1985 to 1991, then proceeded to lose two-thirds of their value over the next 14 years. In the U.S., the price run up was less extreme: house prices rose 82% from November 2001 to their peak in June 2006. Since the peak, house prices have fallen 10% with 10% to 15% further to go.

Japan was slow to write-down its bad loans. That's because its industrial groups, or keiretsu, had tight links with banks, so when a bank got in trouble it was often quietly bailed out temporarily with loans or investments from other members of the corporate group. In the U.S., banks are quicker to take write-downs and so far we've used Sovereign Wealth Funds (SWFs) to recapitalize the banks.

The lesson we should learn from Japan is that the sooner we face reality, the sooner we can solve our problems and move on to the next period of growth. A larger question is whether we can grow without creating another bubble.
