This study examines the effect of physical attractiveness of recipients on donations decisions in a prosocial microlending market by combining both the archival data analysis and controlled experiments. We find that physical attractiveness of female recipients mattters to donors. More attractive recipients tend to have a larger share of male donors, implying that male (female) donors are more (less) favorable toward those recipients. On the contrary, the physical attractiveness of male recipients did not change the composition significantly. Our experiments show that this is partly because male donors give more to more attractive female recipients because of their intuitive preference, simply liking the attractive female more. These findings have implications for the beauty effect in crowd-driven platforms and provide guidance for recipients seeking donation from crowds.
