内群体偏爱如何影响个人捐赠决策：一项实验室实验研究
How in-group favoritism affects individual donation decisions: A laboratory experimental study
摘要
This paper uses a multi-recipient dictator game to examine whether in-group favoritism increases donations to in-group institutions but decreases donations to out-group institutions. By comparing individual donations to in-group institutions, out-group institutions, and total donations in different treatments, I find that the total donations are similar in different treatments, but the donations each institution receives are different. Individuals donate equally when they encounter two out-group institutions, but, they tend to donate a larger amount to the in-group institution and a smaller amount to the out-group institution. These results demonstrate that donations to the in-group institution due to the effect of in-group favoritism increase at the expense of donations to the out-group institution.
中文摘要
本文采用多接受者独裁者博弈实验，考察内群体偏袒是否会增加对内群体机构的捐赠，同时减少对外群体机构的捐赠。通过比较不同实验处理中个体对内群体机构、外群体机构及总捐赠额的差异，本研究发现：不同处理下的总捐赠额相近，但各机构获得的捐赠额存在差异。当个体面对两个外群体机构时，其捐赠行为呈现均等化特征；然而，当面对内群体机构与外群体机构时，个体倾向于向内群体机构捐赠更多金额，而向外群体机构捐赠更少金额。这些结果表明，内群体偏袒效应导致对内群体机构的捐赠增加，是以牺牲对外群体机构的捐赠为代价的。
