摘要
This paper develops a model for the forward and spot exchange rate which allows for the presence of a Markov switching risk premium in the forward market and considers the issue of testing the unbiased forward exchange rate (LIFER) hypothesis. Using US/UK data, it is shown that the LIFER hypothesis cannot be rejected, provided that instrumental variables are used to account for within-regime correlation between explanatory variables and disturbances in the Markov switching model on which the test is based.
