Abstract:
In this paper we follow an empirical approach to examine the implications of the Fisher hypothesis, namely cointegration linking interest rates and in°ation, and stationarity of the real interest rate implying in turn homogeneity of the potential equilibrium relation. The considered sample is an unbalanced panel and comprises monthly time series data from more than 100 economies covering at most a period of about 45 years. In total more than 31000 observations enter our empirical analysis. From cross sectional error correction and dynamic OLS regressions we ¯nd that the parameters of the dynamic relation depend on economic conditions like the level of in°ation or in°ation uncertainty. Moreover, our results indicate that from a world wide perspective the (average) Fisher coe±cient is less than unity. Applying panel unit root and cointegration tests indicate that interest rates and in°ation are cointegrated.
