A Note on International Real Interest Rate Differentials
实证检验了各国实际利率是否相等，发现统计检验强烈拒绝实际利率相等的假设。
Abstrac t-This note empirically examines the issue of real interest rate equalization across countries. The equality of real interest rates is implied by two frequently employed concepts of equilibrium in international asset (capital) and commodity markets and imposes certain time series restrictions on ex post real interest rates. Statistical tests of these restrictions strongly reject the hypothesis that real interest rates have been equal across countries.
