The goal of the paper is to test the importance of such factors as fairness, reciprocation and altruism in subjects' reasoning. I consider the phantom treatment where subjects are randomly matched with the decisions that were made in the (separate) benchmark treatment, and two-type treatments...

Experimental studies have modeled individual funding of social projects as contributions to a threshold public good. We examine donors' behavior when they face multiple threshold public goods and the possibility of coordinating their contributions via an intermediary. Employing the experimental...

This paper is a single-project meta-analysis of four experiments that first model charitable giving as individual contributions to a multiplicity of competing threshold public goods. Given the centrality of the coordination dilemma as the number of recipients increases, we pool 15,936...

We study cheating as a collective-risk social dilemma in a group setting in which individuals are asked to report their actual outcomes. Misreporting their outcomes increases the individual’s earnings but when the sum of claims in the group reaches a certain threshold, a risk of collective...

Psychological game theory can provide rational-choice-based framing effects; frames influence beliefs, beliefs influence motivations. We explain this theoretically and explore empirical relevance experimentally. In a 2x2 design of one-shot public good games we show that frames affect subject’s...
