Dynamic open economy models with time-separable, deterministic utilities fail to account for observed dynamics of exchange rates and international relative prices and quantities. This paper examines the ability of extensions of existing open economy models to account for exchange rates,...

The authors investigate an international monetary business-cycle model in which agents face monetary policy processes that incorporate regime shifts. In any given period agents cannot directly observe the policy regime, but instead form beliefs that are updated via Bayesian learning. As a...

This paper contains a dynamic general equilibrium model with an endogenous process for growth and business cycles driven partly by technological discovery and diffusion. The model integrates two branches of the literature. One is literature on Schumpeterian, or "quality ladder," models, in which...

This paper examines monetary regime switching in Canada and the United States and the implications of regime switching for exchange rates and key nominal and real macroeconomic aggregates for the two countries. Evidence of Markov regime switching in the process governing monetary base growth and...

This paper considers network externalities from currency acceptability as a determinant of observed persistence of dollarization in Latin American countries. A model with efficiencies from establishing a network of currency users is constructed. Model implications are then tested using a unique...
