Under current law, on January 1, 2013, there's going to be a massive fiscal cliff of large spending cuts and tax increases.

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.

I think one of the lessons of the Depression - and this is something that Franklin Roosevelt demonstrated - was that when orthodoxy fails, then you need to try new things. And he was very willing to try unorthodox approaches when the orthodox approach had shown that it was not adequate.

The sources of deflation are not a mystery. Deflation is in almost all cases a side effect of a collapse of aggregate demand.. a drop in spending so severe that producers must cut prices on an ongoing basis in order to find buyers.

I am confident that we will meet whatever challenges the future may bring.

If current trends continue, the typical U.S. worker will be considerably more productive several decades from now. Thus, one might argue that letting future generations bear the burden of population aging is appropriate, as they will likely be richer than we are even taking that burden into account.
