Abstract:
This paper studies the validity of the long-run purchasing parity hypothesis. The five currencies of
interest in this study are the U.S. dollar, the U.K. pound sterling, the German mark, the French franc, and
the Japanese yen. I attempt two approaches to test the long-run PPP hypothesis. First, I test for unit roots
of the real exchange rates themselves. Second, I examine the cointegration relationship between the
foreign dollar price level and the Canadian price level. Results show that the long-run PPP hypothesis
cannot be confirmed.
