We estimate the U.S. New Keynesian Phillips Curve in time-frequency domain with continuous wavelet tools to provide integrated answers three controversial issues. (1) Has short-run tradeoff been stable? (2) What has role of expectations? (3) Is there a long-run tradeoff? First, we find that is limited some specific episodes and no evidence nonlinearities or structural breaks. Second, households...

In this paper, we use identification-robust methods to assess the empirical adequacy of a New Keynesian Phillips Curve (NKPC) equation. We focus on the Gali and Gertler’s (1999) specification, on both U.S. and Canadian data. Two variants of the model are studied: one based on a rationalexpectations assumption, and a modification to the latter which consists in using survey data on inflation exp...

This paper examines the New Keynesian Phillips curve (NKPC) in Thailand in the two decades from 1993 to 2014 marked by the two large crises of 1997 and 2008. This analysis is significant because expectations and economic growth in Thailand may have been influenced by incidents including coups and natural disasters. The findings are summarized as follows. First, the empirical analysis shows that...

This paper examines a model of dynamic price adjustment based on the assumption that information disseminates slowly throughout the population. Compared to the commonly used sticky-price model, this sticky-information model displays three related properties that are more consistent with accepted views about the effects of monetary policy. First, disinflations are always contractionary (although...

We propose a Bayesian approach to test the New Keynesian Phillips Curve (NKPC) both as an exact relation and as a noisy/potentially misspecified model. We do so in order to reconcile the contradicting evidence that the NKPC is rejected by a Wald test but nevertheless it provides a good approximation of inflation dynamics. We apply the proposed approach to US and EMU data. When the NKPC is teste...
