Currency Fluctuations vs. Interest and Inflation Differentials : Does the Double Equality Hold ?


  • Jean-Christian LAMBELET


Combining, as it does, three fundamental propositions ( uncovered interest rate parity, relative PPP, international equalization of the real return on capital), the double equality is found to hold in the long run with a striking degree of precision and reability when tested by means of a sample of 18 industrialized OECD countries over the 1976-1994 period.
