Jim Hamilton asks the question, "Are we asking too much of monetary policy?"
But I would nevertheless caution that we need to be open to the possibility that no matter how low the Fed brings its target rate, it may not arrest the unfolding financial disaster. Unless the intention is to go all the way with enough inflation to avert the defaults, that means we need an exit strategy-- some point at which we all admit that further monetary stimulus is doing nothing more than generating inflation, and at which point we acknowledge that the goal for monetary policy is no longer the heroic objective of making bad loans become good, but instead the more modest but also more attainable objective of making sure that fluctuations in the purchasing power of a dollar are not themselves a separate destabilizing influence.
