We consider the interaction between monetary and fiscal policies, in one country and in a monetary union. In a Nash equilibrium, at least one of the outcomes (output and inflation) are more extreme than the ideal points of both policy authorities. We allow very general stochastic shocks to the...

Consider a world of traders separated in geographic, economic, or social space. Honest trade offers larger gains for more distant traders, but frequencies of meetings, and information flows about cheating, have local bias. Honesty is self-enforcing only between pairs of sufficiently close...

We model the electoral politics of redistribution. Taxation has efficiency and equity effects. Citizens and parties care about inequality in addition to their private concerns for consumption and votes respectively. In equilibrium, each party's strategy can be implemented by a proportional...

The Coase Theorem states that costless enforcement of voluntary agreements yields efficient outcomes. We argue that previous treatments fail to recognize the full meaning of voluntariness: it requires a two-stage game; a non-cooperative participation decision, followed by Coaseian bargaining only...

Paul Samuelson is probably the most important economist of the second half of the twentieth century. His research publications; his introductory textbook; his articles on topical questions of economic policy; and his interactions with numerous students, colleagues, policy makers, and the wider...

We consider the interaction between the monetary policy of a common central bank in a monetary union, and the separate fiscal policies of the member countries. We construct a model of the Barro-Gordon type extended to many countries and countercyclical fiscal stabilization policies. Each...

Transaction-cost politics views economic policy-making as a political process constrained by asymmetric information and limited commitment possibilities. This paper examines some implications of this perspective for less-developed countries (LDCs) considering policy reform. It emphasizes that...
