By means of a laboratory experiment with 508 participants, we study the impact of ego depletion on revealed distributional preferences. Subjects are exposed to a social preference identification procedure in 2 consecutive weeks. In the treatment intervention, they accomplish an ego-depletion task before being exposed to the procedure in 1 of the 2 weeks, and in the control intervention they accomplish a control task. Half of the subjects are exposed to the intervention in Week 1 and the other half in Week 2. Our design allows us to cleanly identify 3 separate effects on social preferences: (a) the effect of exposing subjects to the social preference identification procedure a second time, (b) the effect of the intervention per se, and (c) the effect of ego depletion in particular. We find that only the intervention per se has an effect on social preferences for some types, whereas the ego-depletion task does not have a significant effect compared with the control task, and preferences display a considerable degree of stability over time.

分配偏好和自我耗竭。

通过对 508 名参与者的实验室实验，我们研究了自我耗竭对显露分布偏好的影响。受试者在连续 2 周内接受社会偏好识别程序。在治疗干预中，他们在 2 周中的 1 周内完成一项自我消耗任务，然后再接受手术，而在控制干预中，他们完成一项控制任务。一半的受试者在第 1 周接受干预，另一半在第 2 周接受干预。我们的设计使我们能够清楚地确定对社会偏好的 3 种独立影响：(a) 将受试者第二次暴露于社会偏好识别程序时间，（b）干预本身的影响，以及（c）特别是自我耗竭的影响。
