Time-Varying Persistence of Inflation : Evidence from a Wavelet-Based Approach

Boubaker, Heni - 2017

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...
