How Is Charitable Giving Influenced by Suggestions of a Contribution-Level?
The field experiment presented in this video shows that the level of donations can be raised by suggesting a concrete contribution amount to potential donors. As MAJA ADENA explains, the effects were threefold: the average donation level rose, the different suggested amounts were respectively donated more often in the treatment groups during the experiment, and they were still more often after the experiment, when no amounts were suggested anymore.
