Three well-known single equation cointegration tests are employed to test for purchasing power parity (PPP) in updated version of the data set developed by Taylor (2002). Results of the tests differ somewhat. The Engle-Granger two-step procedure indicates substantial support for PPP with respect...

In recent work Im, Lee, and Enders (2006) use stationary instrumental variables to test for cointegrating relationships. The advantage of their approach is that the t-statistics are asymptotically standard normal and the familiar critical values of the normal distribution may be used to assess...

Purchasing power parity has been the subject of many empirical studies. Much of this work has focused on recent history in developed countries. This paper reports results of tests for nonlinear, mean reversion of the real exchange rate for a less-developed country, Mexico, using a previously...
