This study finds that Purchasing Power Parity holds in the long-run for Azerbaijan, Kazakhstan and Kyrgyzstan, based on Breitung’s (2001) rank tests for cointegration. Results from further analysis indicates that nominal exchange rates and relative prices are nonlinearly interrelated. Trade...

Much interest has been paid recently to the nonlinear cointegrating relations existing among economic variables. Various testing procedures are already available to test for the existence of nonlinear cointegration. For example, Breitung (2001) proposes rank tests and his testing procedure has...

The finding of nonlinear cointegration between Asian exchange rates with the corresponding relatives prices and aggregate price levels based on Breitung’s (2001) nonparametric rank tests reinforces previous validations of Purchasing Power Parity by the parametric testing procedures. Hence, in...

Recent advances in nonlinear cointegration analysis find evidence for a nonlinear long-run relation between the U.S. interest rate and inflation. Employing the Breitung's (2001) rank tests for nonlinear cointegration, we find herein little evidence for cointegration in the U.S. data. We also...
