Most political and economic theorists point to moral hazard in teams as the main obstacle to lobbies' collective action. In this paper, we address this important issue with a coalition-formation game. In the process of doing so, we characterize equilibrium lobby structures both in the absence...

This paper reports experimental tests of two alternative explanations of how players use focal points to select equilibria in one-shot coordination games. Cognitive hierarchy theory explains coordination as the result of common beliefs about players’ pre-reflective inclinations towards the...

Psychological game theory can provide a rational choice explanation of framing effects; frames influence beliefs, and beliefs influence motivations. We explain this point theoretically, and explore its empirical relevance experimentally. In a 2×2-factorial framing design of one-shot public good...

Power indices suggest that adding new members to a voting body may increase the power of an existing member, even if the number of votes of all existing members and the decision rule remain constant. This phenomenon is known as the paradox of new members. This paper shows that the paradox has...

We replicate the experiment introduced by Fischbacher, Gächter and Fehr (2001) measuring the level of conditional cooperation in a one-shot public goods game. We collected data of 160 students from four different locations in urban and rural Russia. Like Fischbacher et al. we can classify about...

This paper investigates fundraising mechanisms for the private provision of a public good which utilize competition as an incentive device for contributions. Theory predicts that “all-pay” competition is particularly effective for fundraising. Within this class of mechanisms different types...

Recent theoretical research on oligopolistic competition suggests that prices may increase when more firms compete in a market. However, this finding is based on comparative-static analyses of static models, which overlook the possibility that sellers may be able to charge supra-competitive...

We study collusive behaviour in experimental duopolies that compete in prices under dynamic demand conditions. In one treatment the demand grows at a constant rate. In the other treatment the demand declines at another constant rate. The rates are chosen so that the evolution of the demand in...

This paper presents an experimental study of dynamic indefinite horizon R&D races with uncertainty and multiple prizes. The theoretical predictions are highly sensitive: small parameter changes determine whether technological competition is sustained, or converges into a market structure with an...

This paper investigates mechanisms for the private provision of a public good which utilize competition to incentivize contributions. Theory predicts that “all-pay” competition is particularly effective for fundraising. Within this class of mechanisms different types of lotteries and all-pay...
