In a model of repeated games, we determine the conditions under which cooperation is an equilibrium outcome among the G-20 countries. We consider first, that members are uncertain about the lifespan of the G-20. Second, the nature of member countries and their interrelations can change because...

The authors (Cason, Friedman and Hopkins, Review of Economic Studies, 2014) claimed that control treatments (using simultaneous matching in discrete time) replicate previous results that exhibit weak or no cycles. After correcting two mathematical mistakes in their cycles tripwire algorithm, we...

This article experimentally studies a two-stage elimination contest and compares its performance with a one-stage contest. Contrary to the theory, the two-stage contest generates higher revenue than the equivalent one-stage contest. There is significant over-dissipation in both stages of the...

Many resource allocation contests have the property that individuals undertake costly actions to appropriate a potentially divisible resource. We design an experiment to compare individuals’ decisions across three resource allocation contests which are isomorphic under risk-neutrality. The...

A contest is a situation in which individuals or groups expend costly resources while competing to win a specific prize. The variety of economic situations that can be described as contests has attracted enormous attention from economic theorists. Despite the extensive theoretical research of...

We experimentally investigate the effect of social identification and information feedback on individual behavior in contests. In all treatments we find significant over-expenditure of effort relative to the standard theoretical predictions. Identifying subjects through photo display decreases...

We conduct an experimental analysis of a best-of-three contest. Intermediate prizes lead to higher efforts, while increasing the role of luck (as opposed to effort) leads to lower efforts. Both intermediate prizes and luck reduce the probability of contest ending in two rounds. The patterns of...

This laboratory experiment studies two-stage contests between political parties. In the first stage, parties run their primaries and in the second stage the winners of the primaries compete in the general election. The resource expenditures in the first stage by the winning candidates are...

A common finding in social sciences is that member change hinders group functioning and performance. However, questions remain as to why member change negatively affects group performance and what are some ways to alleviate the negative effects of member change on performance? To answer these...
