Using eight unit root tests and a stationarity test and three decades of monthly data for the currencies between the US, Germany, UK and Switzerland, we find that, while spot exchange rates are non-stationary, long maturity forward rates are stationary

This paper presents unprecedented exchange rate forecasting results, based upon a new model that approximates the gap between the fundamental equilibrium exchange rate and the actual exchange rate with the long-maturity forward exchange rate. The theoretical derivation of our forecasting...

This paper shows that error correction models assuming that long-maturity forward rates are stationary outperform the random walk in out of sample forecasting at forecasting horizons mostly above one year, for US dollar exchange rates against nine industrial countries' currencies, using the...
