There is an intense debate going on in the first-class cabin of Economics Airlines about the direction in which our plane should be pointed. And while those of us back in the cheap seats don't get to help decide, knowing where we will land is of intense interest to all of us. This week we listen in on the debate, in the form of speeches and academic postings passed back from first class for the rest of us to read. This type of debate also occurred when Greenspan held rates down at an abnormally low level for a very long time. The unintended consequence of that move was a housing and debt/leverage bubble. Are there potential unintended consequences to Bernanke's current monetary policy, which some are calling Quantitative Easing Infinity? I suggest you put up your tray tables and fasten your seatbelts – the ride could get bumpy as we explore QE Infinity: Unintended Consequences.
