I don't quite understand why the asymmetry of risks facing the Fed under the current economic environment doesn't carry more weight in the discussion.
Whatever the Fed does they risk making a mistake. If they tighten policy too late, they risk higher inflation. If they tighten too quickly they risk pushing the economy into deflation.
Considering that the Fed absolutely knows how to fight inflation but has no proven technique for fixing deflation it seems as if the clear policy bias should be toward risking the problem you know how to solve.
And yet the Fed seems to fear an inflation rate that overshoots their target far more than they fear one that undershoots, even though undershooting is far more problematic.
