This paper estimates the dynamics of adjustment to long run purchasing power parity (PPP) using data for 18 mayor bilateral US dollar exchange rates, over the post-Bretton Woods period, in a non-linear framework. We use new unit root and cointegration tests that do not assume a specific...

Taylor (2002) claims that Purchasing Power Parity (PPP) has held over the 20th century based on strong evidence of stationarity for century-long real exchange rates for 20 countries. Lopez et al. (2005), however, found much weaker evidence of PPP with alternative lag selection methods. We...

The large appreciation and depreciation of the US dollar in the 1980s stimulated an important debate on the usefulness of unit root tests in the presence of structural breaks. In this paper, we propose a simple model to describe the evolution of the real exchange rate. We then propose a more...

This paper tests the relative version of purchasing power parity (PPP) for a set of ten Asian developing countries using panel cointegration framework. We employ ¡®between-dimension¡¯ dynamic OLS estimator as proposed by Pedroni (2001b). The test results overwhelmingly reject the PPP hypothesis.

In this paper we re-examine whether purchasing power parity holds in the long run in China from a two-steps procedure correcting outliers and testing unit roots. Thus, the efficient unit root tests developed by Elliott, Rothenberg and Stock (1996) and Ng and Perron (2001) are applied on the...

This paper examines the empirical validity of purchasing power parity (PPP) hypothesis in a Sri Lankan context using exchange rates for six foreign currencies during the period January 1986 to November 2000. Both graphical and econometric methods are used in the analysis. Graphical analysis...

This paper tests the relative version of purchasing power parity (PPP) for a set of ten Asian developing countries using panel cointegration framework. We employ 'between-dimension' dynamic OLS estimator as proposed by Pedroni (2001b). The test results overwhelmingly reject the PPP hypothesis.

This paper models the dynamics of the adjustment process of Indonesian purchasing power parity (PPP) relative to US, Japan and Singapore by employing a nonlinear framework, which is recently shown to be appropriate in the presence of transaction costs associated with international trade. Using...

The results of this paper complement the recent findings of real exchange rates as stationary processes. The standard procedure of applying a battery of unit root tests can be problematic since the tests are sensitive to the specifics of the time-series process. The novelty of the approach we...

The aim of this article is to provide additional evidence on the fulfilment of the Purchasing Power Parity hypothesis in the so-called Mediterranean countries. In order to test for the empirical validity of such hypothesis, we have applied two types of unit root tests. The first group is due to...
