This paper proposes an estimate of the Hungarian real exchange rate=20 misalignments using fractionally integrated threshold models (FI-STARMA and=20= FI-TARMA=20 processes). This allows us to simultaneously take into account two types of=20 persistence: a long memory behavior due to the...

This paper presents a 2-regime SETAR model where the process under examination is governed by a long-memory process in the first regime and a short-memory process in the second regime. Persistence properties are studied and methods for locating the threshold parameter are proposed. Such a...
