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...

The macroeconomic analysis of fiscal policy is usually based on one of two canonical models--the Barro-Ramsey model of infinitely-lived families or the Diamond-Samuelson model of overlapping generations. This paper argues that neither model is satisfactory and suggests an alternative. In the...

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...

Fluctuations in real GNP have traditionally been viewed as transitory deviations from a deterministic time trend. The purpose of this paper is to review some of the recent developments that have led to a new view of output fluctuations and then to provide some additional evidence. Using post-war...

This paper present some new empirical evidence on the extent of world capital-market integration. The first set of tests carried out uses data from different countries to compare internationally expected marginal rates of substitution between consumption on different dates. If residents of...

There is a large and growing empirical literature that tests forthe existence of asset-price bubbles or "sunspot" equilibria -- equilibria unrelated to market fundamentals. Our view is that even tests for non-stationary asset-price bubbles should not be interpreted as such. In the present paper...

This paper studies optimal fiscal policy in an economy where heterogeneous agents with uncertain lifetimes coexist. We show that some plausible social welfare functions lead to time-inconsistent optimal plans, and we suggest restrictions on social preferences that avoid the problem. The...
