This paper estimates the complete historical US price data by employing a relatively new statistical methodology based on long memory. We consider, in addition to the standard case, the possibility of nonlinearities in the form of nonlinear deterministic trends as well as the possibility that...

This paper reports a two-stage analysis of inflation persistence using monthly data from 11 IT countries and, for comparison, the US, a non IT country with a history of credible monetary policy. First, we estimate inflation persistence in a rolling-window fractional integration setting using the...

We propose a new long-memory model with a time-varying fractional integration parameter, evolving non-linearly according to a Logistic Smooth Transition Autoregressive (LSTAR) specification. To estimate the time-varying fractional integration parameter, we implement a method based on the wavelet...

We investigate the empirics of the persistence in the inflation series for 13 OECD countries that use an inflation targeting regime. We estimate persistence in the pre- and post-targeting periods using the fractional integration framework suggested by Kim and Phillips (2006, 2000) and Phillips...
