Moral suasion and charitable giving

We investigate the effect of moral suasion on charitable giving. Participants in an online experiment choose between two allocations, one of which includes a donation to a well-known charity organization. Before making this choice, they receive one of several messages potentially involving a moral argument from another participant. We find that the use of consequentialist and deontological arguments has a positive impact on the donation rate. Men respond strongly to consequentialist arguments, while women are less responsive to moral suasion altogether. Messages based on virtue ethics, ethical egoism, and a simple donation imperative are ineffective.
