Is the Fisher effect robust? Further evidence

Abstract

New international evidence exists on the Fisher effect in the United States, the United Kingdom, Japan, Germany and Canada over the modern (post-March 1973) floating exchange rate experience. Some puzzling data has been observed which suggests that the Fisher effect appears to be strong only for particular sample periods. It has also been reported in the literature that the Fisher effect is more likely in the long run, and that it is not common across economic regimes. This study sheds some light on these controversial issues taking advantage of more powerful tests for unit roots and cointegration. The findings for the Fisher effect contrast with previous results, especially those of Mishkin. The empirical results appear to accord with historical observations on interest rate movements in the five countries. Some important results are as follows: (1) the Fisher effect is not robust to policy changes; (2) there is strong evidence of a long-run Fisher effect for the United States, Germany, and Japan, but li...
