Mariana Garcia Schmidt as well as Mike Woodford are lighting upward the meshing alongside a pNoah Smith, Marginal Revolution, econbrowser.
This is a specially of import voice, every bit it seemed to me that criterion New-Keynesian models create the new-Fisherian result. i = r + Epi is a steady soil inwards all models. In old-Keynesian models, it was an unstable steady state, therefore an involvement charge per unit of measurement peg leads to explosive inflation or deflation. But inwards new-Keynesian models, an involvement charge per unit of measurement peg is the stable/indeterminate case. There are every bit good many equilibria, but if yous heighten involvement rates, inflation ever ends upward ascent to encounter the higher involvement rate.
What I tin glean from the slides is that Garcia Schmidt as well as Woodford agree: Yes, this is what happens inwards rational expectations or perfect foresight versions of the new-Keynesian model. But if yous add together learning mechanisms, it goes away.
My start reaction is relief -- if Woodford says it is a prediction of the criterion perfect foresight / rational expectations version, that agency I didn't screw upward somewhere. And if ane has to resort to learning as well as non-rational expectations to acquire rid of a result, the battle is one-half won.
But that's solely preliminary relief. Schmidt as well as Woodford hope a newspaper soon, which volition undoubtedly live good crafted as well as challenging.
For to a greater extent than on the issue, hither is a a previous weblog post. Section 3.1 ff of "Monetary policy alongside involvement on reserves" has a sum novel Keynesian model alongside the Fisherian result. And a wry prediction: the Fed volition heighten rates to caput off inflation, that volition motility the inflation, as well as then the Fed volition congratulate itself on having headed off the inflation. I also suspect that models alongside restricted liquidity (no involvement on reserves) attain plough over a temporary turn down inwards inflation, but without that liquidity nosotros similar a shot volition acquire sum Fisherian results. But that's only a conjecture therefore far. My last foray into learning inwards new-Keynesian models, which didn't cease well.
Why postal service now? Garcia Schmidt as well as Woodford clearly volition convey a thoughtful as well as sophisticated paper, on what I cry upward is a deep as well as of import point. I hope to encourage others to read as well as assistance to digest the paper.
