This study examines the validity of the purchasing power parity (PPP) in Turkey for annual data from 1953 to 2009. While results from both the ADF unit root and the DF-GLS unit root test indicate mixed results, PPP holds for Turkey with the presence of structural breaks which are obtained by...

The univariate and panel Lagrange Multiplier (LM) unit root tests with one and two structural breaks proposed by Lee and Strazicich (2003, 2004) which are considerably more powerful than traditional tests are employed to investigate whether the purchasing power parity (PPP) theory holds true for...

This paper is aim to test the validity of the purchasing power parity hypothesis by analyzing the transition economies such as Bulgaria, Czech Republic, Hungary, Poland, Romania. For this purpose, the minimum LM unit root test with one structural break is applied to real exchange rate data.

The purchasing power parity (PPP) has been amongst the most tested theories in the international finance literature. The empirical findings from the extant literature for the PPP hypothesis are mixed. This article applies univariate and panel Lagrange Multiplier (LM) unit root tests with one and...
