This paper presents a theoretical model of exchange-rate determination intended to address the forward premium puzzle. It also explains the empirical observation that risk premiums depend on interest differentials. The model's closed-form solution indicates that currency risk premiums depend on...

In this paper, I provide evidence that currency stop-loss orders contribute to rapid, self-reinforcing price movements, or "price cascades". Stop-loss orders, which instruct a dealer to buy (sell) a certain amount of currency at the market rate once the rate has risen (fallen) to a prespecified...
