Long Run Relationship between Real Exchange Rate and Real Interest Rate Differentials : The Cointegration Approach

Despite the centrality of the theoretical relationship between real exchange rates and real interest rates differential in open economy macroeconomics, its empirical evidence, particularly when cointegration methods are used, is rather mixed. The study uses IFS, IMF data for India and US for the period of 1993:M04 to 2003:M09. It employs both Engle-Granger and Johansen tests for presence of cointegration. However, it could not found empirical support in favour of the above relationship. The result is robust for different measures of real interest rate differentials
