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...

Univariate studies of the hypothesis of unit roots in real exchange rates have yielded consensus point estimates of the half-life of deviations from purchasing power parity of between three to five years. However, least squares-based estimates of half-lives are biased downward. Accordingly, we...
