Equilibrium Grading Policies With Implications for Female Interest in STEM Courses
研究发现STEM课程更严格的评分政策降低了学生选课率，尤其对女性影响更大；通过模型分析，均衡评分政策可缩小STEM性别差距并提高总选课率。
We show that stricter grading policies in STEM courses reduce STEM enrollment, especially for women. We estimate a model of student demand for courses and optimal effort choices given professor grading policies. Grading policies are treated as equilibrium objects that in part depend on student demand for courses. Differences in demand for STEM and non‐STEM courses explain much of why STEM classes give lower grades. Restrictions on grading policies that equalize average grades across classes reduce the STEM gender gap and increase overall enrollment in STEM classes.
