We study the patterns of political selection in majoritarian versus proportional systems. Political parties face a trade-off in choosing the mix of high and low quality candidates: high quality candidates are valuable to the voters, and thus help to win the elections, but they crowd out the...

Does welfare improve when ?firms are better informed about the state of the economy and can better coordinate their decisions? We address this question in an elementary business-cycle model that highlights how the dispersion of information can be the source of both nominal and real rigidity....

We consider real pre-Hilbert modules H on Archimedean f-algebras A with unit e. We provide conditions on A and H such that a Riesz representation theorem for bounded/continuous A-linear operators holds.

Frustration, anger, and aggression have important consequences for economic and social behavior, concerning for example monopoly pricing, contracting, bargaining, tra¢ c safety, violence, and politics. Drawing on insights from psychology, we develop a formal approach to exploring how...

We develop, and experimentally test, models of informal agreements. Agents are assumed to be honest but suffer costs of overcoming temptations. We extend two classical bargaining solutions ?split-the-difference and deal-me-out ?to this informal agreement setting. For each solution there are two...

We analyze the effort allocation choices of incumbent politicians when voters are uncertain about politician preferences. There is a pervasive incentive to “posture” by overproviding effort to pursue divisive policies, even if all voters would strictly prefer to have a consensus policy...

Existant studies of confl ict, negotiation and international relations do not take into account that the institutions used to resolve disputes shape the incentives for entering disputes in the first place. Because engagement in a costly and destructive war is the `punishment' for entering a...

This paper applies mechanism design to the study of international con flict resolution. Standard mechanisms in which an arbitrator can enforce her decisions are usually not feasible because disputants are sovereign entities. Nevertheless, we find that this limitation is inconsequential. Despite...

In this paper we review some recent work on public intervention in economic environments where ?firms undertake investments in research or in physical assets, and then choose appropriate business practices to extract pro?ts from the outcomes of the investment process. Public policies may take...

Recent applications to the modeling of emission permit markets by means of stochastic dynamic general equilibrium models look into the relative merits of different policy mechanisms under uncertainty. The approach taken in these studies is to assume the existence of an emission constraints that...
