I notice he has an undergraduate in maths, then went straight into a PhD in economics. My conjecture: I bet he never took Intro Economics, or anything vaguely similar. I bet he waded straight into the mathematical deep end. And so he never really learned economics. So he took the Fisher identity (nominal interest rates = real interest rates + expected inflation), added monetary super-neutrality (equilibrium real rates are independent of monetary policy in the long run), and ran with it. He never distinguished between the equilibrium thought-experiment and the stability thought-experiment. If you explain this in words, as you have to in Intro Economics, you have to get it right.Worthwhile Canadian Initiative: Why "everyone" should be forced to take Intro Economics

I guess Kocherlakota (and Williamson) made a wonderful discovery -- the fed can keep the inflation rate constant by just holding the fed funds rate constant, since the rate of real interest is constant. It's a mathematical certainty! And makes the job so much simpler... wonder why we never thought of it...
Paul Volcker's life in 1979-1982 would have been so much easier if only he had had access to Kocherlakota's and Williamson's brains--NOT!!!Jed Harris Nails It
