Assuming that asset markets are complete and arbitrage-free, the exchange rate can be expressed in terms of observables in a multicountry, multigood general equilibrium economy. In contrast to existing models of the exchange rate, this general model allows for international differences in...

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

This Paper analyses the exchange rate in a ‘no-arbitrage’ or ‘real business cycle’ equilibrium model and provides empirical evidence for this model vis-a-vis PPP. Our contribution is to show, based on a generalization of the equilibrium model of exchange rates, that (i) the test equation...

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...
