This paper studies the effects of demand and supply shocks in the global crude oil market on several measures of countries’ external balance, including the oil trade balance, the non-oil trade balance, the current account and changes in net foreign assets (NFA) during 1975– 2004. We...

We propose a stylized exchange rate model based on diversity and weight ofopinion. Our model departs from standard assumptions in that we allow forheterogeneous agents. We show that such a model can explain both the observedvolatility and the persistence of real and nominal exchange rate...

We propose a nonlinear econometric model that can explain both the observed volatility and the persistence of real and nominal exchange rates. The model implies that near equilibrium, the nominal exchange rate will be well approximated by a random walk process. Large departures from...

We propose an exchange rate model that can explain both the observed volatility and the persistence of real and nominal exchange rate movements and thus in some measure resolves Rogoff?s (1996) purchasing power parity puzzle. Our analysis reconciles the well-known difficulties in beating the...
