Bush today did selected Ben Bernanke to replace Alan Greenspan as Fed chairman. Bernanke is best known for his November 2002 speech Deflation: Making Sure "It" Doesn’t Happen Here.
[D]eflation is generally the result of low and falling aggregate demand. The basic prescription for preventing deflation is therefore straightforward, at least in principle: Use monetary and fiscal policy as needed to support aggregate spending, in a manner as nearly consistent as possible with full utilization of economic resources and low and stable inflation. In other words, the best way to get out of trouble is not to get into it in the first place.
…
.. under a fiat (that is, paper) money system, a government (in practice, the central bank in cooperation with other agencies) should always be able to generate increased nominal spending and inflation, even when the short-term nominal interest rate is at zero.Like gold, U.S. dollars have value only to the extent that they are strictly limited in supply. But the U.S. government has a technology, called a printing press (or, today, its electronic equivalent), that allows it to produce as many U.S. dollars as it wishes at essentially no cost. By increasing the number of U.S. dollars in circulation, or even by credibly threatening to do so, the U.S. government can also reduce the value of a dollar in terms of goods and services, which is equivalent to raising the prices in dollars of those goods and services. We conclude that, under a paper-money system, a determined government can always generate higher spending and hence positive inflation.
Bernanke says that in case of a recession -and the next one will come at some point in time for sure-, which could induce deflationary tendencies, he will support an all out effort by the fed, the banking system and the government to inflate the money supply early and in non trivial volumes.
Indeed one could argue that the fed has already taken some of the steps Bernanke did announce in that 2002 speech. In case of doubt, look at your bills and compare them to the bills you got at the time of the last Deflation Scare three years ago.
There is little experience on the effect of such intervention. The one that comes to mind is the Weimar Republic.
With Bernanke at the top of the fed, financial assets will not fall, but they will lose value. Prices will not fall either, but wages may well do so. But then, If You Don’t Eat or Drive, Inflation’s No Problem.
