Purchasing Power Parity Tests in Cointegrated Panels

Author

Abstract

This paper employs recently developed techniques for testing hypotheses in cointegrated panels to test the strong version of purchasing power parity for a panel of post Bretton Woods data. We compare results using fully modifed and dynamic OLS approaches, and strongly reject the hypothesis. We also introduce a new between-dimension dynamic OLS estimator and find that the between-dimensio n FMOLS and DOLS estimates of the long-run deviation from purchasing power parity are larger than the correspondin g within-dimension estimates. Finally, we attempt to reconcile these rejections with the mixed findings that have been reported in panel unit root studies.
