Garcia Schmidt As Well As Woodford On Neo-Fisherian Economcs
Mariana Garcia Schmidt as well as Mike Woodford are lighting upward the mesh amongst a pNoah Smith, Marginal Revolution, econbrowser.
This is a specially of import voice, equally it seemed to me that measure New-Keynesian models hit the new-Fisherian result. i = r + Epi is a steady set down inward all models. In old-Keynesian models, it was an unstable steady state, hence an involvement charge per unit of measurement peg leads to explosive inflation or deflation. But inward new-Keynesian models, an involvement charge per unit of measurement peg is the stable/indeterminate case. There are likewise many equilibria, but if you lot heighten involvement rates, inflation ever ends upward rise to come across 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 inward rational expectations or perfect foresight versions of the new-Keynesian model. But if you lot add together learning mechanisms, it goes away.
My starting fourth dimension reaction is relief -- if Woodford says it is a prediction of the measure perfect foresight / rational expectations version, that way I didn't screw upward somewhere. And if i 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 exclusively 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 spider web log post. Section 3.1 ff of "Monetary policy amongst involvement on reserves" has a sum novel Keynesian model amongst the Fisherian result. And a wry prediction: the Fed volition heighten rates to caput off inflation, that volition displace the inflation, as well as then the Fed volition congratulate itself on having headed off the inflation. I also suspect that models amongst restricted liquidity (no involvement on reserves) hit orbit a temporary reject inward inflation, but without that liquidity nosotros directly volition acquire sum Fisherian results. But that's only a conjecture hence far. My last foray into learning inward new-Keynesian models, which didn't destination well.
Why postal service now? Garcia Schmidt as well as Woodford clearly volition accept a thoughtful as well as sophisticated paper, on what I recall is a deep as well as of import point. I hope to encourage others to read as well as aid to digest the paper.
