Learning and New Keynesian Models.
John Barrdear at the Bank of England just posted an interesting paper, Towards a New Keynesian theory of the price level. Like Garcia Schmidt and Woodford, it changes the information structure of the standard model to avoid the standard model's problems.Modifying the standard New-Keynesian model to replace firms' full information and sticky prices with flexible prices and dispersed information, and imposing mild and plausible restrictions on the monetary authority's decision rule, produces the striking results that (i) there exists a unique and globally stable steady-state rate of inflation, despite the possibility of a lower bound on nominal interest rates; and (ii) in the vicinity of steady-state, the price level is determinate (and not just the rate of inflation), despite the central bank targeting inflation. ... The model admits a determinate, stable solution with no role for sunspot shocks when the monetary authority responds by less than one-for-one to changes in expected inflation, including under an interest rate peg....I haven't read this one yet either. I'm posting for anyone following these issues. Like Garcia Schmidt and Woodford, I also hope that others will read the papers and help to figure out if they really work as advertised.
