| Sumario: | This study tests the unbiased forward exchange rate hypothesis for the Mexican exchange market. Instead of the linear regression base model, we use a nonlinear Markov switching model. The model identifies two states in the behavior of the forward exchange rate: one in which the null hypothesis of efficiency holds and the other one in which it does not. The results show that the unbiased hypothesis is rejected for both the 30 and 90 day forward rates when using a lineal model. However, when using the two-state Markov switching model we cannot reject the null hypothesis for the 30 day forward rate in the state identified as the efficient but we reject it in other state. For the 90 day forward rate we cannot distinguish between the two states. Therefore, the nonlinear two-state Markov switching model is far superior to the traditional single state linear regression model to test the unbiased forward exchange rate hypothesis. Our study provides evidence that the hypothesis of efficiency is rejected in periods of high uncertainty in the economy and policy decisions. |
