January 2005Testing Uncovered Interest Parity at Short and Long Horizons during the Post-Bretton Woods Era
with Menzie D. Chinn: w11077
The hypothesis that interest rate differentials are unbiased predictors of future exchange rate movements has been almost universally rejected in empirical studies. In contrast to previous studies, which have used short-horizon data, we test this hypothesis using interest rates on longer-maturity bonds for the U.S., Germany, Japan and Canada. The results of these long-horizon regressions are much more positive -- the coefficients on interest differentials are of the correct sign, and most are closer to the predicted value of unity than to zero. These results are robust to the use of different data frequencies, sample periods, yield definitions, and base currencies. We appeal to an econometric interpretation of the results, which focuses on the presence of simultaneity in a cointegration fr...
November 1998Long-Horizon Uncovered Interest Rate Parity
with Menzie D. Chinn: w6797
Uncovered interest parity (UIP) has been almost universally rejected in studies of exchange rate movements, although there is little consensus on why it fails. In contrast to previous studies, which have used relatively short-horizon data, we test UIP using interest rates on longer-maturity bonds for the G-7 countries. These long-horizon regressions yield much more support for UIP -- all the coefficients on interest differentials are of the correct sign, and almost all are closer to the UIP value of unity than to the zero coefficient implied by the random walk hypothesis. We then use a small macroeconomic model to explain the differences between the short- and long-horizon results. Regressions run on data generated by stochastic simulations replicate the important regularities in the a...
