As support for traditional asset models of the foreign exchange market fades, there is growing interest in more general models that include flows from international trade and international investment. One advantage of flow models is that they fit naturally into the recent literature on...

Pippenger and Phillips (forthcoming) show how four common pitfalls cause cointegration tests to reject the law of one price when in fact it holds. They conclude that there is no reliable evidence that rejects the LOP. We consider a stronger test, half lives. The literature suggests that half...

The exchange rate literature contains two inconsistent strands. There is a large theoretical and empirical literature on overshooting. In that literature overshooting is an important explanation for exchange rate volatility. A separate literature says that exchange rates are martingales and that...

Three puzzles are closely related to the forward-bias puzzle and the failure of uncovered interest parity: (1) UIP failure is greater for short than long maturities, (2) forward bias is larger between developed than between developing countries and (3) there is no systematic forward bias in...

Several articles claim that Eichenbaum and Evans (1995) shows that nominal exchange rates experience a delayed version of Dornbusch overshooting. These same articles usually claim that impulse responses similar to those in Eichenbaum and Evans are evidence of such overshooting. But Eichenbaum...

When covered interest parity holds, as appears to be the case, the forward exchange rate is not the expected future spot rate. As a result: (1) in general covered and uncovered interest parity are mutually inconsistent; (2) the standard equation that produces the forward-bias puzzle is...

A complete solution to the forward-bias puzzle should provide an econometric solution and an economic explanation for that solution. A complete solution should also explain the closely related failure of uncovered interest parity. In addition it should explain some related anomalies. One such...

The forward-bias puzzle is probably the most important puzzle in international finance. But there is a simple solution. Covered interest parity implies that the forward-bias puzzle is the result of two omitted variables: (1) the future change in the forward exchange rate and (2) the future...
