This paper studies exchange rate behavior in models with moving long-run equilibria incorporating alternative price-adjustment mechanisms.The paper demonstrates that price-adjustment rules proposed by Mussa andby Barro and Grossman yield models that are empirically indistinguishable from each...

In recent years, many countries have instituted monetary reforms aimed at improving anti-inflation credibility. Is it a problem, however, that international welfare spillover effects seldom receive much consideration in the design of monetary reforms? Surprisingly, the answer may be no. Under...

The paper develops a simple stochastic new open economy macroeconomic model based on sticky nominal wages. Explicit solution of the wage-setting problem under uncertainty allows one to analyze the effects of the monetary regime on welfare, expected output, and the expected terms of trade....

In this paper I focus on two specific hazard areas in the transition from Stage Two to Stage Three of European economic and monetary union (EMU), as well as on some key problems of Stage Three that EMU's monetary and fiscal structures appear ill-prepared to handle. The transitional hazards are...

This paper develops an explicitly stochastic new open economy macroeconomics' model, which can potentially be used to explore the qualitative and quantitative welfare differences between alternative exchange rate regimes. A crucial feature is that we do not simplify by assuming certainty...

Once one recognizes that governments borrow international reserves and exercise other policy options to defend fixed exchange rates during currency crises, the question arises: What factors determine a government's decision to abandon a currency peg or hang on? In a setting of purposeful action...

This paper develops a dynamic continuous-time model in which international risk sharing can yield substantial welfare gains through its positive effect on expected consumption growth. The mechanism linking global diversification to growth is an attendant world portfolio shift from safe, but...
