We propose a new family of mechanisms, whereby players may give more or less directly to one another. A cornerstone case is the regular linear public goods mechanism (LPGM), where all contribute into a single common group account, the total amount of which is then distributed equally among...

When multiple charities, social programs and community projects simultaneously vie for funding, donors risk miscoordinating their contributions leading to an inefficient distribution of funding across projects. Community chests and other intermediary organizations facilitate coordination among...

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 compare a partners condition where the same small group of subjects plays arepeated public good game to astrangers condition where subjects play this game in changing group formations.Subjects in the partners conditioncontribute from the first period on significantly more to the public good...

We report experimental findings on the role of charitable promises in bargaining settings. We vary the enforceability of such promises within variants of ultimatum games where the proposer suggest a split between himself, the responder and a char-itable donation. By reneging on initial pledges,...
