Elsewhere, menu costs have been shown to result in more inflation persistence than contracting costs in the presence of real rigidities. This note demonstrates that the reverse is true if the average contract length is endogenous, for plausible parameter values

The all-gap Phillips curve (PC) explains inflation by expected inflation and an activity variable such as output or the unemployment rate, but with both inflation and the activity variable measured relative to their stochastic trends and thus as gaps. We study this relationship with minimal...

We review single-equation methods for estimating the hybrid New Keynesian Phillips curve (NKPC) and then apply those methods to U.S. quarterly data for 1955?2007. Estimating the hybrid NKPC by the generalized method of moments yields stable coefficients with a large role for expected future...
