In a public goods experiment, subjects can vary over a period of stochasticlength two contribution levels: one is publicly observable (their cheap talkstated intention), while the other is not seen by the others (their secretintention). When the period suddenly stops, participants are restricted...

The key element of models of contest is the Contest Success Function (CSF) which specifiesthe winning probabilities of agents. The existing axiomatizations of CSFs assume thatcontestants can make only one type of investment. This paper generalizes these axiomatizationsto the case where each...

The key element of models of contest is the Contest Success Function (CSF) whichspecifies the winning probabilities of agents. We provide an axiomatization of two parametricfamilies of CSF’s. In the first, the winning probability of each agent depends onthe investments and a vector of...

The variable threat-bargaining model of Nash (1953) assumes that threats in the senseof binding commitments as to what one will do if bargaining ends in conflict, are chosenbefore bargaining. By comparison, late threats to be chosen after bargaining end in conflict,appear more natural and would...

In this paper we study the robustness of the deadline effect in bargaininggames using constant and slowly decreasing pies, different time horizons,and both constant and alternating role modes. With decreasing pies efficiency requires early agreements while constant pies allow for efficient late...

This article examines the nature of human behavior in a nested socialdilemma referred to as the Spillover Game. Players are divided into twogroups with positive production interdependencies. Based on theoreticallyderived opportunistic, local, and global optima, our experimental...

In this paper, we study a voluntary contribution mechanism withone-way communication. The relevance of one person’s words is assessedby assigning exogeniously the role of the ‘communicator’ to onegroup member. Contrary to the view that the mutual exchange ofpromises is necessary for the...

One-way communication has been found to substantially increasecontributions in linear voluntary contribution mechanisms. We confirmthe robustness of this result in the presence of income heterogeneity.

Previous research indicates that risky and uncertain marginal returnsfrom the public good significantly lower contributions. This paper presentsexperimental results illustrating that the effects of risk and uncertainty dependon the employed parameterization. Specifically, if the value of the...
