I go from thinking bernacke has not got any clue to the idea he thinks he doing everything he can to save the economy and knows he's propping it up everywhere....
1). bernacke can't be a moron to get as far as he has, though he may turn out to be very damaging for many americans.
2). I've known a number of otherwise very bright economists who don't quite agree with the Austrian school (ie chicago school economists). So just because they have such a background that may be very free market, etc, they may still not quite see what's playing out right now. And many of these folks would feel the data will guide them to make good decisions.
3). I think bernacke and co. are actually very worried. If they weren't they would not have been as aggressive with cutting rates. They also may believe they can inflate their way out of this mess successfully.
So in conclusion, assume bernacke is a ethically good person, who is intelligent, but has a very basic flawed theoretical foundation in monetary policy. He knows he might be wrong, as much as he believes his foundation and so is secretely probably very nervous... Put all this together in the pot, with the election year and hints from bush to delay the recession, etc. and I think you have his current position.
Now don't attack me too much, these are assumptions, and I don't completely rule out the possibility of double talk etc, ppt trying to burn shorts and other games they may be playing in a very ruthless fashion, I just don't think they are really that savvy. (though I'm worried they could be that slippery).
