A donation may have ambiguous costs or ambiguous benefits. Behavior in a laboratory experiment suggests that individuals use this ambiguity strategically as a moral wiggle room to act less generously without feeling guilty. Such excuse-driven behavior is more pronounced when the costs of a...

We conduct an experiment in which subjects make a series of decisions of allocating an endowment of £10 between themselves and a passive recipient that is either a charity or the experimenter. When making these decisions subjects are informed that one of them will be chosen randomly at the end...

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,...

We augment a standard dictator game to investigate how preferences for an environmental project relate to willingness to limit others’ choices. We explore this issue by distinguishing three student groups: economists, environmental economists, and environmental social scientists. We find that...

This paper studies the construction of social preferences in the lab. Experimental subjects have the opportunity to donate to a charity and to allocate money in a conventional dictator game. The results show that charitable donations and dictator game allocations are positively correlated. The...

Experimental research on generosity has focused predominantly on behavior in the monetary domain, although many real life decisions take place in the non-monetary domain. Investigating generosity preferences in the non-monetary domain is important to understand a large class of situations...

There has been an increasing interest in altruistic behaviour in the domain of losses recently. Nevertheless, there is no consensus in whether the monetary losses make individuals more generous or more selfish. Although almost all relevant studies rely on a dictator game to study altruistic...

We investigate the effect of a donation incentive tied to contributions to a public good when group members can decide on the size of the donation to be made. An up to 20 % donation of the public good was implemented either exogenously or endogenously by group members. In the Vote treatment,...

In different treatments of an intergenerational common resource experiment, monetary payoff maximization by each generation causes either negative or positive externalities for future generations. Two behavioral types have been observed previously in single generation games: equity motivated...
