Foreign exchange market efficiency is commonly investigated by Fama-regression tests of uncovered interest parity (UIP). In this paper, we conjecture a speculative UIP relationship which implies that exchange rate changes comprise a time-varying risk component in addition to the forward...

In this paper, we derive the dynamics and assess the economic value of currency speculation by formalizing the concept of a trader inaction range. We show that exchange rate returns comprise a time-varying risk-premium and that uncovered interest parity (UIP) holds in a speculative sense. The...

We study the properties of foreign exchange risk premiums that can explain the forward bias puzzle, defined as the tendency of high-interest rate currencies to appreciate rather than depreciate. These risk premiums arise endogenously from the no-arbitrage condition relating the term structure of...
