This paper uses three methods to assess movements of real exchange rates in the ECCU over time. First, the purchasing power parity hypothesis is tested and then used to provide a benchmark for equilibrium real exchange rates in the region. Second, a fundamentals-based equilibrium real exchange...

Consensus estimates put the half-life of deviations from purchasing power parity (PPP) at about four years (Rogoff, 1996). However, conventional least squares estimates of half-lives are biased downward. Accordingly, as a preferred measure of the persistence of real exchange rate shocks, this...
