This paper provides a general framework that accounts for the decay of the average contribution observed in most experiments on voluntary contributions to a public good. Each player balances her material utility loss from contributing with her psychological utility loss of deviating from her...

Cet article relate les résultats d’une expérience portant sur les incitations à contribuer à la protection de l’environnement. Il s’agit plus précisément de comparer l’efficacité des politiques de préservation des biens environnementaux et celles visant à améliorer les...

Andreoni (1995) showed that pure framing effects may influence contribution in Voluntary Contribution Mechanisms (VCM) by comparing a standard public goods game, called the positive frame condition (giving to the public good), with a negative frame condition (taking from the public good) where...

Embezzlement is a major concern in various settings. By means of a sequential modified dictator game, we investigate theoretically and experimentally whether making information more transparent and reducing the number of intermediaries in transfer chains can reduce embezzlement and improve the...

We develop a model that accounts for the decay of the average contribution observed in experiments on voluntary contributions to a public good. The novel idea is that people's moral motivation is "weak." Their judgment about the right contribution depends on observed contributions by group...
