We find that the forward premium puzzle (FPP) and the "dollar trade" anomaly are intimately linked. Both anomalies are almost exclusively driven by the cross-time component. By contrast, the "carry trade" anomaly is driven largely by the cross-currency component. The simplest model that the data do not reject features a highly persistent a...
