Autoregression-Based Estimation of the New Keynesian Phillips Curve

Lanne, Markku and Luoto, Jani (2011): Autoregression-Based Estimation of the New Keynesian Phillips Curve.

Abstract

We propose an estimation method of the new Keynesian Phillips curve (NKPC) based on a univariate noncausal autoregressive model for the inflation rate. By construction, our approach avoids a number of problems related to the GMM estimation of the NKPC. We estimate the hybrid NKPC with quarterly U.S. data (1955:1-2010:3), and both expected future inflation and lagged inflation are found important in determining the inflation rate, with the former clearly dominating. Moreover, inflation persistence turns out to be intrinsic rather than inherited from a persistent driving process.
