One-way communication has been found to substantially increase contributions in linear voluntary contribution mechanisms. We confirm the robustness of this result in the presence of income heterogeneity. -- Public goods experiment ; Cheap talk ; Heterogeneous endowments

In this paper, we study a voluntary contribution mechanism with one-way communication. The relevance of one person's words is assessed by assigning exogenously the role of the "communicator" to one group member. Contrary to the view that the mutual exchange of promises is necessary for the...

We report on an experiment designed to explore whether a written expression of disapproval affects future levels of cooperation. In between two identical public goods games, participants play a mini dictator game that, depending on the treatment, either gives or does not give the recipient the...

Based on an axiomatically derived provision rule allowing community members to endogenously determine which, if any, public project should be provided, we perform experiments where (i) not all parties benefit from provision, and (ii) the projects' "costs" can be negative. In the tradition of...

We report on an experiment designed to explore whether and how anger affects future levels of cooperation. Participants play three consecutive one-shot games. In between two identical two-person public goods games there is a mini dictator game that, depending on the treatment, either gives or...

The satisficing approach is generalized and applied to finite n-person games. Based on direct elicitation of aspirations, we formally define the concept of satisficing, which does not exclude (prior-free) optimality but includes it as a border case. We also review some experiments on strategic...
