This paper provides first and second-order approximation methods for the solution of non-linear dynamic stochastic models in which the exogenous state variables follow conditionally linear stochastic processes displaying time-varying risk. The first-order approximation is consistent with a...

This paper studies the theoretical conditions under which price stability is the optimal policy in a two-country open-economy model with imperfect competition and price stickiness. Special conditions on the levels of country-specific distortionary taxation and the intratemporal and intertemporal...

We propose a theory of exchange rate determination under interest rate rules in a two-country model. We first show that simple interest rate feedback rules can determine a unique and stable equilibrium without any explicit reaction to the nominal exchange rate. We characterize how the behavior...

EMU is a completely new policy regime which has significant economic implications and which, it is hoped, will ultimately enhance the role of Europe on the world stage. EMU and Economic Policy in Europe takes stock of the initial experiences of EMU and assesses the challenges which will have to...
