Abstract
This note tests the joint hypothesis of rational expectations and perfect substitutability between assets denominated in US dollars, deutsche marks and pound sterling. The hypothesis implies that the forecast errors from the uncovered interest rate parity condition follow a white noise process. Using a test based on the frequency domain properties of white noise processes, the hypothesis is not rejected on a sample of monthly observations from January 1974 to December 1981.
