Japan-U.S. Real Exchange Rate Behaviour: Evidence from Linear and Non-Linear Endogenous Break Tests
This paper explores the mean reversion behaviour of three Japanese real exchange rates during January 1980â€“January 2010. The CPI- and PPI-based real yen/USD rates and real effective yen rates are examined using newly improved unit root tests allowing for endogenous break(s) in the linear and non-linear manner. We identify structural breaks in 1985 and 1997/98, respectively, via the linear tests from Zivot and Andrews (1992) and Lumsdaine and Papell (1997), but the results were mostly against the PPP hypothesis. The test from Saikkonen and LÃ¼tkepohl (2002), however, provides sufficient support for the non-linear adjustment of real exchange rates towards long-run PPP (purchasing power parity), which suggests the goods market integration between the two nations. The exchange rate misalignment is somewhat less evident after the Plaza Accord 1985, and stronger evidence for PPP is found in the post-1999 period. This is supported by a smaller persistency of real exchange (half-life
