A panel study on real interest rate parity in East Asian countries: Pre- and post-liberalization era

This study examines the mean reverting behavior of real interest differentials in ten Asian economies using Japan as the base country. We obtain a number of interesting results: first, the conventional ADF test fails to support Real Interest Parity (RIP) for at least half of the countries, even for the post-financial liberalization period. Second, the evidence based on panel unit root tests demonstrates that real interest rate differentials exhibit mean reverting behavior and are characterized by long-memory dynamics. Finally, the evidence suggests that deviations from RIP have a half-life of approximately 6 to 7 months.
