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...

There are situations in which competitors ally to pursue a common objective. This simultaneous presence of cooperation and competition is called coopetition and we study it theoretically and experimentally in a group contest setup. More concretely, we analyze a group contest with a new sharing...

The paper presents experimental evidence on the impact of managers and their incentives on the behavior of group members in intergroup contests. I find that members follow the nonbinding investment recommendations of their group manager in particular if the managers payoff does not depend on the...

In a veto game, we investigate the effects of "buyout" which allows non-veto players strategically form an intermediate coalition. We report two main experimental findings in this paper. First, the frequency of intermediate coalition formation is much lower than predicted by theory, regardless...

This paper examines behavior (the oretically and experimentally) in a two-stage group contest where the fi rst stage comprises of intra - group contests, followed by an inter-group contest in the second stage. Rewards accrue only to the members of the winning group in the inter-group contest,...

We isolate strategic and non-strategic motivations of sanctioning in a repeated public goods game. In two experimental treatments, subjects play the public goods game with the possibility to sanction others. In the STANDARD sanctions treatment, each subject learns about the sanctions received in...

In this experiment, we endogenize the choice of which contribution scheme is implemented in a public goods game. We investigate three rule-based contribution schemes. In a first step, players agree on a common group provision level using the principle of the smallest common denominator....

This paper experimentally examines a procedurally fair provision mechanism allowing members of a small community to determine, via their bids, which of four alternative public projects to implement. Previous experiments with positive cost projects have demonstrated that the mechanism is...
