Why High Incentives Cause Repugnance: a Framed Field Experiment
通过田野实验和调查实验发现，多数人支持或中立，但少数人（17%）因担心高激励说服他人而禁止高额金钱激励，抽奖机制可减少反对，且公众比伦理委员会更支持高激励。
Abstract Why are high monetary payments prohibited for certain goods, thereby causing shortages in their supply? I conduct (i) a framed field experiment with a general population sample and (ii) a survey experiment with this sample and with ethics committees. In the experiment, participants can prohibit others from being offered money to register as stem-cell donors. I document that, whereas the majority of participants do not respond to changes in the incentives (63%) or become more in favour of the offer with higher incentives (20%), a minority of 17% prohibit high incentives. I show that this minority wants to protect individuals who are persuaded by high incentives. I also show that a lottery scheme reduces their objections to high incentives. Finally, I document that the public is much more supportive of high incentives than are ethics committees.
