The Foreign Exchange Market: A Random Walk with a Dragging Anchor.

This paper explores some anomalies in the foreign exchange market. It is hard to find evidence of either short-term overshooting or of longer-term reversion to an equilibrium. The forward exchange rate contains virtually no information on future spot rates. Discussions with practitioners indicate that longer-term speculation based on fundamentals is strictly limited, and survey data and other evidence suggest that expectations and speculation are based on a variety of models. The interplay between speculation based on fundamentals, and on a random walk, or Chartist, approach, influences the outcome. This endorses the prior model of J. A. Frankel and K. A. Froot.
