Abstract

This study uses univariate and multivariate unit root tests to analyze the random walk behavior of real exchange rates for the period 1979-1989. The univariate test fails to reject the random walk model, but the multivariate test indicates that part of the real exchange rates is predictable, a result supporting purchasing power parity. Further analysis of the random walk component in real exchange rates shows that it is quite persistent: for all currencies it takes about five to eight years for this shock to diminish to half its size.
