This paper characterizes analytically the optimal tariff of a large one-sector economy with monopolistic competition and firm heterogeneity in general equilibrium, thereby extending the small-country results of Demidova and Rodriguez-Clare (JIE, 2009) and the homogeneous firms framework of Gros...

We examine regulation as a repeated game between a regulator and a utility facing a Markovian sequence of demands. Sunk capital would be expropriated by a regulator concerned only with the short-run interests of consumers. There exist rate of return regulatory policies supporting efficient...

A two-country dynamic general-equilibrium model with imperfect competition and price stickiness is considered. This work shows the conditions under which price stability can implement the flexible-price allocation as a Nash equilibrium. This is possible if and only if both countries maintain a...

The paper investigates the sustainability of cooperative rules for the conduct of macroeconomic policy in a two-country world. The problem is set out as a supergame in which the threat strategy is to switch to a Nash non-cooperative equilibrium. A number of possible non-cooperative equilibria...

Theoretical and experimental studies of noncooperative games increasingly recognize Nash equilibrium as a limiting outcome of players‘ repeated interaction. This note, while sharing that view, illustrates and advocates combined use of convex optimization and differential equations, the purpose...

We explore how outcomes of trade policy retaliation (Nash tariff games) are affected when trade simultaneously takes places geographically across countries and through time via financial intermediation. In such models deficits and surpluses in goods trade are endogenously determined, and...

We examine wage competition in a model where identical workers choose the number of jobs to apply for and identical firms simultaneously post a wage. The Nash equilibrium of this game exhibits the following properties: (i) an equilibrium where workers apply for just one job exhibits unemployment...

We analyse welfare-maximizing monetary policy in a dynamic general equilibrium two-country model with price stickiness and imperfect competition. In this context, a typical terms of trade externality affects policy interaction between independent monetary authorities. Unlike the existing...

This Paper tackles the issue of international fiscal coordination in a world where markets are integrated but national governments are sovereign. The consequences of capital market liberalization to national fiscal policies and possible remedies to resulting inefficiencies are analysed. A...

We study the international monetary policy design problem within an optimizing two-country sticky price model, where each country faces a short run trade-off between output and inflation. The model is sufficiently tractable to solve analytically. We find that in the Nash equilibrium, the policy...
