Purchasing power parity in ASEAN+3: an application of panel unit root tests

Panel Unit Root Tests with GLS-Detrending With an Application to Purchasing Power Parity

We combined recent developments in univariate and multivariate unit root testing in order to construct a more-powerful panel unit root test. We extended the GLS-detrending procedure of Elliott, Rothenberg, and Stock (1996) to a panel Augmented Dickey-Fuller test. The finite sample power properties of the new test demonstrate a very large gain when compared to existing tests, especially for smal...

Purchasing Power Parity during Currency Crises: A Panel Unit Root Test under Structural Breaks

In this paper the relevance of the PPP as a long-run relationship is studied using a panel of Latin American and Asian countries. We investigate the stationarity of real exchange rates by applying a new panel unit root test that is robust to structural breaks due to currency crises. It turns out that the long-run PPP relationship is relevant for the Asian countries, which experienced a flexible...

Purchasing Power Parity Tests in Cointegrated Panels

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 modiŽ ed and dynamic OLS approaches , and strongly reject the hypothesis . We also introduce a new between-dimensio n dynamic OLS estimator and Ž nd that the between-dimensio n ...
