We model a dynamic public good contribution game, where players are (naturally) formed into groups. The groups are exogenously placed in a sequence, with limited information available to players about their groups' position in the sequence. Contribution decisions are made by players...

Similar to Levati and Neugebauer (2001), a clock is used by which participants can vary their individual contributions for voluntarily providing a public good. As time goes by, participants either in(de)crease their contribution gradually or keep it constant. Groups of two poorly and two richly...

The emergence of Pay-What-You-Want (PWYW) business models as a successful alternative to conventional uniform pricing brings up new questions related to the task of pricing. We investigate the effect of a reduction of privacy on consumers' purchase decisions (whether to buy, and if so how much...

Quasilinear preferences on a public good and a numeraire good are limits of preferences where both goods are normal. The set of equilibria of the voluntary contribution (or private provision) game is easily characterized under quasilinearity by: top valuators aggregately contribute their common...

In the recent literature, several hypotheses have been put forward in order to explain the decline of contributions in repeated public good games. We present results of an experiment which allows to evaluate these hypotheses. The main characteristics of our experimental design are a variation of...

We report an experiment comparing sequential and simultaneous contributions to a public good in a quasi-linear two-person setting (Varian, Journal of Public Economics, 1994). Our findings support the theoretical argument that sequential contributions result in lower overall provision than...

In this paper we examine voluntary contributions to a public good when the timing of contributions is endogenously determined by contributors, focusing on the simple quasi-linear setting with two players (Varian, 1994). We show that the move order that is predicted to emerge is sensitive to how...

We report an experiment comparing sequential and simultaneous contributions to a public good in a quasi-linear two-person setting. In one parameterization we find that overall provision is lower under sequential than simultaneous contributions, as predicted, but the distribution of contributions...

This paper extends theory and experimentation in the context of two parties in a group who contribute to a public good with a provision point. This study analyzes the voluntary contributions game in which a public good is provided if and only if the sum of contributions meets or exceeds a...

We study the interplay between leading-by-example and group identity in a public goods game experiment. A common identity between the leader and her followers is beneficial for cooperation: average contributions are more than 30% higher than in a treatment where no identity was induced. In two...
