The Importance of Being Marginal: Gender Differences in Generosity
通过上门募捐的现场实验发现，男性和女性在慷慨程度上无差异，但当容易回避募捐者时，女性慷慨度下降。结构估计表明，女性更可能处于捐赠的边缘，部分原因是利他主义分布更集中。
Do men and women have different social preferences? Previous findings are contradictory. We provide a potential explanation using evidence from a field experiment. In a door-to-door solicitation, men and women are equally generous, but women become less generous when it becomes easy to avoid the solicitor. Our structural estimates of the social preference parameters suggest an explanation: women are more likely to be on the margin of giving, partly because of a less dispersed distribution of altruism. We find similar results for the willingness to complete an unpaid survey; women are more likely to be on the margin of participation.
