Might the economy benefit from a cold shower?

This story from The Economist asks the question that former Fed chairman Alan Greenspan probably never asked. Whether or not Ben Bernanke wonders about this from time to time is an intriguing thought.

Does America need a recession?
THE late Rudi Dornbusch, an economist at the Massachusetts Institute of Technology, once remarked: “None of the post-war expansions died of old age. They were all murdered by the Fed.” Every recession since 1945, with the exception of the one in 2001, was preceded by a sharp rise in inflation that forced the central bank to raise interest rates. But today's Federal Reserve is no serial killer. It seems keener on blood transfusions than on bloodletting.

When the Fed cut its discount rate on August 17th, it admitted for the first time that the credit crunch could hurt the economy. The markets are betting it will soon cut its main federal funds rate. Economists are arguing vigorously about how much damage falling house prices and the subprime mortgage crisis will do. But there is one question that is rarely asked: even if a downturn is in the offing, should the Fed try to prevent it?

Many of America's current financial troubles can be blamed on the mildness of the 2001 recession after the dotcom bubble burst. After its longest unbroken expansion in history, GDP did not even fall for two consecutive quarters, the traditional definition of a recession. It is popularly argued that the tameness of the downturn was the benign result of the American economy's increased flexibility, better inventory control and the Fed's firmer grip on inflation. But the economy also received the biggest monetary and fiscal boost in its history.
...
This does not mean that the Fed should follow the advice of Andrew Mellon, the treasury secretary, after the 1929 crash: “liquidate labour, liquidate stocks, liquidate the farmers, and liquidate real estate...It will purge the rottenness out of the system.” America's output fell by 30% as the Fed sat on its hands. As a scholar of the Great Depression, Ben Bernanke, the Fed's chairman, will not make that mistake. Central banks must stop recessions from turning into deep depressions. But it may be wrong to prevent them altogether.

Of course, even if a recession were in America's long-term economic interest, it would be political suicide. A central banker who mentioned the idea might soon be out of a job. But that should not stop undiplomatic economists asking whether a recession once in a while might actually be a good thing.

It would take a super-human will for Ben Bernanke to not try to prevent a recession with an election bearing down on these United States. The interesting question will be how he responds to a weakening economy if inflation is still above the Fed's comfort zone.

Don't be surprised to hear renewed talk of re-jiggering the Consumer Price Index - some new calculations are said to knock a full point off of the headline number, something that may be quite helpful in the months ahead.
