“她”与“她”的匹配:高等教育中性别匹配带来的成绩提升

The match between ‘She’ and ‘Her’: Performance gains from gender match in higher education

中文摘要

本文使用来自孟加拉国一个高评分经济学项目的新颖且保密的行政数据集,表明由女性教师授课的女学生相对于男学生,在成绩表现上约获得 0.09 个标准差的提升。此外,我发现了提示性证据:在较长期的结果上,如学位完成时间和进入经济学硕士项目的可能性,女学生从累积接触女性教师中获得的收益大于男学生。学生被准随机分配到必修课程,且无法选择课程或教师,这缓解了自选择方面的担忧。我排除了以下解释:该收益由教师评分中的性别偏好所驱动;并发现该收益似乎是由教师性别本身而非与性别相关的教师特征所驱动,因为在控制可观测的教师特征后,效应仍然很大且统计显著。

Abstract

I use a novel and confidential administrative dataset from a highly rated economics program in Bangladesh to show that female students taught by female instructors gain approximately 9 percent of a standard deviation in grade performance relative to their male counterparts. In addition, I find suggestive evidence that female students benefit more than male students from cumulative exposure to female instructors in longer-term outcomes, such as degree completion time and the likelihood of enrolling in an economics master’s program. The quasi-random allocation of students to mandatory courses, where students cannot select either courses or instructors, alleviates self-selection concerns. I rule out the explanation that the gain is driven by gender preference in teachers’ assessment and find that the gain appears to be driven by instructor gender itself rather than by teacher attributes correlated with gender, as the effect remains large and statistically significant even after controlling for observable teacher characteristics.
