We speculate about how Europe's monetary union will evolve in the next five to ten years. We concentrate on what is likely to be the most important change in that period, namely, the increased number and heterogeneity of the participating states. New members will be sharply different from the...

We revisit Obstfeld and Rogoff's (1995) results on exchange rate dynamics in a two-country, monetary model with incomplete asset markets, stationary net foreign assets, and endogenous nominal interest rate setting a la Taylor (1993). Under flexible prices, the nominal exchange rate exhibits a...

I compare the performance of alternative monetary rules for Canada using an open economy model under incomplete markets. Different rules generate different paths for the markup and the terms of trade. A comparison of welfare levels suggests that flexible inflation targeting, the Bank of...

This paper shows that properly designed interest rate rules can be consistent with maintaining exchange rate stability. It sheds light on the relation between interest rate rules, exchange-rate regimes, and determinacy of the rational expectations equilibrium in a modern macroeconomic framework.

We examine the effect of non-zero, steady-state foreign assets on consumption dynamics in response to productivity shocks in a two-country, dynamic, general equilibrium model. The model generates non-zero steady-state net foreign assets by allowing for different discount factors across...

We develop a stochastic, general equilibrium, two-country model of trade and macroeconomic dynamics. Productivity differs across individual, monopolistically competitive firms in each country. Firms face a sunk entry cost in the domestic market and both fixed and per-unit export costs. Only...

I develop a model that improves upon the recent literature in open economy macroeconomics in that it lends itself more directly to empirical investigation. I solve the stationarity problem that characterizes many existing models by adopting an overlapping generations structure à la Weil (1989)....

This paper builds a framework for the analysis of macroeconomic fluctuations that incorporates the endogenous determination of the number of producers and products over the business cycle. Economic expansions induce higher entry rates by prospective entrants subject to sunk investment costs. The...
