The Long-Run Behavior of the Real Exchange Rate: A Reconsideration

Abstract

Using a new statistical test, this paper provides empirical evidence that the real exchange rate is not a random walk. If the real exchange rate were a random walk, deviations from purchasing power parity could be expected to become unbounded as the forecast horizon became longer. Recently, Christopher A. Sims proposed a test based on Bayesian posterior odds ratios that is designed to discriminate between a unit root and a large but stationary autocorrelation coefficient. This paper applies the Sims test to real exchange rate data for six industrial countries. The results reject the random walk hypothesis. Copyright 1992 by Ohio State University Press.
