In which kinds of unequal circumstances are people most willing to donate money to others? Inequality aversion (Fehr and Schmidt,1999) suggests that when facing inequalities, individuals may donate to equalize outcomes, however, it is not clear whether donators care primarily about the inequality between themselves and their recipients, or whether the inequality among donators themselves is also of concern. We explore the question in an experiment which assigns different degrees of endowment inequality to givers and receivers in a serious of dictator games. We find that the strongest donation behavior arises in the case where inequality is high between givers and receivers, yet inequality is low among the givers. We also find some evidence that when inequality is high among givers, it is not the most advantaged givers who are most generous. The results suggest some behavioral cautions in the policy realm in relying on top wealthy individuals for charity.
