EXCHANGE RATES AND INTEREST RATES: CAN THEIR CAUSALITY EXPLAIN INTERNATIONAL CAPITAL MOBILITY?

This paper provides an alternative methodology for testing the degree of international capital mobility through the analysis of a causality direction between the exchange rate and the interest rate for Sweden. The change of exchange rate regime in Sweden in 1992 is used here to illustrate how the alternative exchange rate regimes, fixed and floating, affect the degree of international capital flows. On the basis of new Granger non-causality testing procedures developed by Toda and Yamamoto (1995), the results exhibit that Granger-causality is unidirectional, running from interest rate to exchange rate under the floating exchange rate regime. The implication of this result is that the hypothesis of high capital mobility is supported only under the floating exchange rate regime.
