Abstract

In this paper we examine the features of the US wage Phillips curve over different time horizons analyzing the original Phillips’ specification on a scale-by-scale basis with data transformed by wavelet and band-pass filtering methods. Our results provide compelling evidence that the wage Phillips curve relationship is frequency-dependent, i.e. it varies across frequency bands. In particular, estimation results over frequency bands beyond the business cycle horizon, where the variables have large coefficient values, are very highly significant and explain a substantial proportion of the total variation of nominal wage changes, suggest that the medium-run may be a correct time frame for the wage Philips’ relationship.
