Abstract
This paper presents a new time series model, called the FI-BREAK model, which is used to describe US inflation, and incorporates long memory and occasional level shifts at a priori unknown locations. It is demonstrated that, even in the presence of such level shifts, the long memory parameter of the FI-BREAK model can be estimated reasonably accurately. For US inflation, it is found that the proposed model's in-sample fit and out-of-sample forecasts are superior over those of single-feature models with long memory or level shifts.
