| Tiivistelmä: | Recent empirical evidence suggests that the time series behavior of the real exchange rate is well approximated by a nonlinear, exponential smooth transition autoregressive (ESTAR) model. This nonlinearity helps resolve a number of puzzles concerning the persistence and volatility of real exchange rates. In this paper, the authors explore whether it may also help resolve the well- known difficulties of exchange rate forecasting. The authors develop a bootstrap test of the random walk hypothesis of the nominal exchange rate, given ESTAR real exchange rate dynamics. The authors find strong evidence of predictability at horizons of 2 to 3 years, but not at shorter horizons. |
