人们长期以来担心物质奖励可能会破坏亲社会动机，从而导致献血量减少。本文通过为期三个月的大规模现场实验和十五个月的随访期（涉及超过 10,000 名以前的献血者）对物质奖励如何影响献血进行了实证检验。我们研究了彩票作为奖励相对于标准邀请、上诉和免费胆固醇测试的效果。平均而言，提供彩票可以使实验期间献血的概率比 46% 的基线献血率提高 5.6 个百分点。我们发现这种效应是由捐赠者积极性较低造成的。而且，实验后并没有观察到捐款减少。 (C) 2019 Elsevier B.V. 保留所有权利。
There is a longstanding concern that material rewards might undermine pro-social motivations, thereby leading to a decrease in blood donations. This paper provides an empirical test of how material rewards affect blood donations in a three-month large-scale field experiment and a fifteen-month follow-up period, involving more than 10,000 previous donors. We examine the efficacy of a lottery ticket as a reward vis-a-vis a standard invitation, an appeal, and a free cholesterol test. The offer of a lottery ticket, on average, increases the probability to donate blood during the experiment by 5.6 percentage points over a baseline donation rate of 46%. We find that this effect is driven by less motivated donors. Moreover, no reduction in donations is observed after the experiment. (C) 2019 Elsevier B.V. All rights reserved.
