Explaining the evolution and maintenance of cooperation among unrelated individuals is one of the fundamental problems in biology and the social sciences. Recent experimental evidence suggests that altruistic punishment is an important mechanism to maintain cooperation among humans. In this...

This paper reports results from a laboratory experiment on network formation among heterogeneous agents. The experimental design extends the Bala-Goyal (2000) model of network formation with decay and two-way flow of benefits by allowing for agents with lower linking costs or higher benefits to...

Centralized sanctioning institutions are of utmost importance for overcoming free-riding tendencies and enforcing outcomes that maximize group welfare in social dilemma situations. However, little is known about how such institutions come into existence. In this paper we investigate, both...

Resources are often allocated in groups through decentralized nonmarket mechanisms. We experimentally investigate groups where a rich representative allocates resources among poorer members, who can announce disapproval by voting for a measure hurting the representative. We examine the effect of...

Existing experimental research on behavior in weakest-link games shows overwhelmingly the inability of people to coordinate on the efficient equilibrium, especially in larger groups. We hypothesize that people will be able to coordinate on efficient outcomes, provided they have sufficient...

En période de crise économique, les besoins de l’Etat augmentent et l’assiette fiscale se réduit ; il est alors courant de voir resurgir dans le débat public la lutte contre les diverses formes de fraude qui reduisent les recettes publiques. Dans ce contexte, on oppose régulièrement...

Tax Liability Side Equivalence (tax LSE) claims that the statutory incidence of a tax is irrelevant for its economic incidence. In gift-exchange labor markets, firms provide a gift to workers by paying high wages, and workers reciprocate by providing high efforts. Tax LSE is theoretically...

This paper reports the results of experiments involving a 3-personcoalitionformation game with an ultimatumbargaining character. The grand coalition was always the efficientcoalition,whereas the values of the 2-personcoalitions are varied such that they lead to an efficiency loss inthe range...
