This paper develops new time series measures of inflation uncertainty in the United States in the postwar period that account for the prospect of changing inflation regimes. The measures are constructed from estimates of a Markov switching model for inflation. Importantly, we show that rational...

A new time-series model is used to reassess the strength of the link between inflation uncertainty and the level of inflation in the United States. The model provides several statistical measures that can be used to examine different aspects of uncertainty. The main finding is that uncertainty...
