Before attacking Krugman (who has a Nobel Prize in this subject, btw) and dismissing him out of hand in favor of random hedge fund guys, please cite evidence, any evidence, that his supposed "partisan" attributes have affected his work or made it less reliable or accurate.
From where I sit, Krugman has been right a lot more often than the competition over the last few decades.
Krugman does not have a nobel prize in the subject. Krugman's nobel prize is in another area in Economics, not monetary policy. His contributions are mainly in trade, which were very important no doubt. But it doesn't make him an expert on monetary policy and inflation. I understand that Economics may look like a single-blob to outsiders, but Economics has a wide range of topics and sometimes they barely intersect.
