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.
