This empirical note applies a simple and powerful nonlinear unit root proposed by Sollis (2009) to test the validity of long-run Purchasing Power Parity (PPP) for Japan's Real Exchange Rate (RER) vis-à-vis its eight trading partner countries. The empirical results indicate that PPP holds for...

This empirical note uses a simple and powerful nonlinear unit root test proposed by Sollis (2009) to test the validity of Purchasing Power Parity (PPP) for Middle Eastern countries. Empirical test results indicate that PPP is valid for most of these Middle Eastern countries, with the exception...

This study applies a simple and powerful nonlinear threshold unit root test proposed by Caner and Hansen (2001) to test the validity of long-run Purchasing Power Parity (PPP) in a sample of nine East Asian countries. The empirical results indicate that PPP holds true for more than half of these...
