Long term inflation concerns

voiced by Ken Rogoff (via Greg Mankiw):

The fact is that around most of the world, inflation ― and eventually inflation expectations ― will keep climbing unless central banks start tightening their monetary policies.

The U.S. is now ground zero for global inflation. Faced with a vicious combination of collapsing housing prices and imploding credit markets, the Fed has been aggressively cutting interest rates to try to stave off a recession.

But even if the Fed does not admit it in its forecasts, the price of this "insurance policy" will almost certainly be higher inflation down the road, and perhaps for several years.

I've looked at inflation here and here and here in the last couple of weeks.
