Abstract

We test the validity of Purchasing Power Parity theory, examining the Real Exchange Rate of 23 OECD countries for mean-reversion. In doing so, we estimate the Hurst exponent which is a well-established estimator of long memory in time series analysis. The innovation of our approach is that we employ the Detrended Fluctuation Analysis (DFA) for the estimation of Hurst on Real Exchange Rates bothin the full sample and also in rolling windows of three different sizes in an attempt to identify possible trends, breaks and the evolution of Hurst through time.
