Abstract: | This paper examines the long-run behavior of the yen/dollar real exchange rate. Several series are spliced to compose long Japanese consumer and wholesale price indices, long U.S. consumer and wholesale price indices, and the yen/dollar exchange rate, from 1879 to 1995. The CPI-based real exchange rate tended to depreciate in the pre-WWII periods, but strongly appreciated in the post-WWII periods. The WPI-based real exchange rate did not show any trend in the pre-WWII periods, but appreciated moderately in the post-WWII periods. The unit root tests were not rejected for the CPI-based real exchange rate series, but some of them were rejected for the WPI-based real exchange rate series, suggesting mean reversion property only for the WPI-based series. The Balassa–Samuelson hypothesis to explain a drift and/or a trend in the real exchange rate series had only a weak support.J. Japan. Int. Econ.,December 1997,11(4), pp. 502–521.
