In many collective action settings, such as decisions on public education or climate change mitigation, actions of a group have welfare consequences for themselves as well as their followers. We conduct laboratory experiments with two-stage predecessor-follower prisoners' dilemma and...

In an ongoing organization, such as a large law partnership, employees are motivated not only by current rewards but also by the prospect of promotion, and the opportunity to influence policy and make rules in the future. This leads to a dynamic programming problem in contract design. We model...

We experimentally study bidder collusion in open ascending auctions for multiple objects. The project is based on the theoretical results by Brusco and Lopomo (1999), who give theoretical support for the following claims: (1) simultaneous ascending bid auctions can be vulnerable to collusion in...

We study how people's predisposition towards altruism, as measured by tools developed by psychologists, affects their behavior in a voluntary contributions public good experiment. Earlier experiments provide evidence against the strong free rider hypothesis; however, contributions to the public...

Competitive equilibria are shown to exist in two-object exchange economies with indivisibilities and additive complementarities in agent valuations between objects, provided that complementarities are common across agents. We further investigate whether the competitive equilibrium can be...

We consider payment schemes in experiments that model infinite-horizon games by using random termination. We compare paying subjects cumulatively for all periods of the game; with paying subjects for the last period only; with paying for one of the periods, chosen randomly. Theoretically,...

Antitrust exemptions granted to businesses under extenuating circumstances are often justified by the argument that they benefit the public by helping producers adjust to otherwise difficult economic circumstances. Such exemptions may allow firms to coordinate their capacities, as was the case...

We survey experimental research on multi-unit auctions with an emphasis on topics that may be of a unifying interest to experimental, as well as theoretical and empiri- cal economists. Topics include static and dynamic multi-unit auctions; combinatorial auctions and efficient auction design;...
