## Abstract According to one strand of the international finance literature, market efficiency implies that the real exchange rate follows a martingale process, in direct conflict with the long‐run absolute purchasing power parity hypothesis, which requires a stationary real exchange rate process.

✦ Synopsis
A time-varying parameter model with Markov-switching conditional heteroscedasticity is employed to investigate two sources of shifts in real interest rates: (1) shifts in the coecients relating the ex ante real rate to the nominal rate, the in¯ation rate and a supply shock variable and (2) unconditional shifts in the variance of the stochastic process. The results underscore the importance of modelling continual change in the ex ante real rate in terms of other economic variables rather than relying on a statistical characterization that permits only a limited number of discrete jumps in the mean of the process.

This study examines the long-term persistence in ex ante real interest rates. According to the long-run Fisher effect, ex ante real ratesÐthe difference between nominal rates and expected in¯ationÐshould be mean-reverting and have no unit root. Empirical evidence on mean reversion has been mixed and
