A team must select among competing projects that differ in their payoff consequences for its members. Each agent chooses a project and exerts costly effort affecting its random completion time. When one or more projects are complete, agents bargain over which one to implement. A consensus...

We study how norms can solve distributional conflict inside a clan and the efficient coordination of collective action in a conflict with an external enemy. We characterize a fully non-cooperative equilibrium in a finite game in which a self-enforcing norm coordinates the members on efficient...

This Paper outlines some issues regarding the interaction of independent fiscal authorities and one central bank in the European monetary union. It points out the possibilities for coordination failures, ranging everywhere from potentially excessive deficits and free-riding problems to...

This paper is a practical guide (a toolkit) for researchers, students and practitioners wishing to introduce randomization as part of a research design in the field. It first covers the rationale for the use of randomization, as a solution to selection bias and a partial solution to publication...

This paper both theoretically and experimentally studies the properties of plurality and approval voting when the majority is divided as a result of information imperfections. The minority backs a third alternative, which the majority views as strictly inferior. The majority thus faces two...

Major bubble episodes are rare events. In this paper, we examine what factors might cause some asset price bubbles to become very large. We recreate, in a laboratory setting, some of the specific institutional features investors in the South Sea Company faced in 1720. Several factors have been...

Two groups of voters of known sizes disagree over a single binary decision to be taken by simple majority. Individuals have different, privately observed intensities of preferences and before voting can buy or sell votes among themselves for money. We study the implication of such trading for...

Theories abound for why individuals give to charity. We conduct a field experiment with donors to a Yale University service club to test the impact of a promise of public recognition on giving. Some may claim that they respond to an offer of public recognition not to improve their social...

The rational-voter model is often criticized on the grounds that two of its central predictions (the paradox of voting and Duverger's law) are at odds with reality. Recent theoretical advances suggest that these empirically unsound predictions might be an artifact of an assumption in those...
