Does the Australian Dollar Real Exchange Rate Really Display Mean Reversion?
Non-stationarity of the real exchange rate is inconsistent with purchasing power parity as a long run equilibrium. This paper applies parametric and non-parametric techniques to data from a trade weighted index to analyse the time series properties of Australia's real exchange rate. In contrast to recent work by Olekalns amd Wilkins (1998) we conclude that shocks to the real exchange rate are infinitely persistent.
