A major puzzle in international finance is the inability of models based on monetary fundamentals to produce better out-of-sample forecasts of the nominal exchange rate than a naive random walk. While prior research has generally evaluated exchange rate forecasts using conventional statistical...

We provide empirical evidence that deviations from uncovered interest rate parity (UIP) display significant nonlinearities, consistent with theories based on transaction costs or limits to speculation. This evidence suggests that the forward bias documented in the literature may be less...

We propose an empirical model for deviations from long-run purchasing power parity (PPP) that simultaneously accounts for three key features: (i) adjustment toward PPP may occur via nominal exchange rates and relative prices at different speeds; (ii) different exchange rate regimes may generate...

We examine the forecasting performance of a range of time-series models of the daily U.S. effective federal funds (FF) rate recently proposed in the literature. We find that: (1) most of the models and predictor variables considered produce satisfactory one-day-ahead forecasts of the FF rate,...
