Abstract

This paper uses recent US data to estimate the new Keynesian Phillips curve (NKPC) with three modifications. Firstly, the variables in the NKPC are found to be nonstationary. Therefore, it is estimated with the time series methods and the cointegrating equations are tested for structural breaks. Secondly, inflationary expectations are proxied with the survey data. Thirdly, unlike in the hybrid NKPC, the effects of the lagged inflation rates are introduced into the dynamic adjustment equations. This offers an opportunity to estimate these dynamic effects with a more general specification instead of the restricted partial adjustment mechanism underlying the hybrid NKPC. Our NKPC, with these changes, is consistent with its underlying micro foundations and forward looking expectations. The results of our NKPC can explain the dynamics of the US inflation rate as well as any other alternative model.
