Incentives and prosocial discomfort: A laboratory experiment
通过实验室实验，研究个人在是否为了慈善而忍受身体不适时，额外个人补偿如何影响其决策，发现私人货币激励与亲社会收益的交互作用小于各自效果之和。
We conducted a within-subject laboratory experiment in which participants decided whether to experience physical discomfort for charity, with or without additional personal compensation. Acceptance decreased with greater discomfort and increased with both larger charitable donations and personal payments. We show that private monetary incentives and prosocial benefits interact in a less-than-additive way: personal compensation raises participation but attenuates the marginal impact of charitable donations, making the combined impact of private and social rewards smaller than the sum of their separate effects. We also find suggestive evidence that the sequencing of compensated and uncompensated choices may change the responsiveness to charitable benefits. Overall, our results indicate that context, especially the presence (and timing) of private rewards, can affect the relationship between incentives and prosocial behavior.
