有求必应？大学重新评分中的性别差异

中文摘要

利用一所大型公立大学的行政数据，我们发现，男生获得由教师作出的有利成绩更改的可能性比女生高18.6%。对学生和教师的调查表明，重新评分请求十分普遍，而且在集约边际上，男生更倾向于提出重新评分请求。我们通过一项有激励的对照实验进一步证实了重新评分请求中的性别差异：结果显示，男生为提出重新评分请求而支付的意愿更高。上述性别差异中，近三分之一源于男女在信念和大五人格特质方面的差异。

Abstract

Using administrative data from a large public university, we show that male students are 18.6 percent more likely than female students to receive favorable grade changes made by instructors. Surveys of students and instructors reveal that regrade requests are prevalent and that male students are more likely to ask for regrades on the intensive margin. We corroborate the gender differences in regrade requests in an incentivized controlled experiment: we find that males have a higher willingness to pay to ask for regrades. Almost a third of the gender difference is due to gender differences in beliefs and the Big Five traits. (JEL D82, D91, I23, J16)
