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 … inflation persistence. We use the sequences of estimated persistence measures from the first stage as dependent variables in the …
