Affirmative Action and Precollege Human Capital
研究美国最高法院恢复平权行动的裁决对大学前人力资本的影响，发现该政策缩小了种族间在成绩、出勤和大学申请上的差距，尤其对成绩分布上半段的学生效果显著。
Though racial affirmative action (AA) policies are widespread in college admissions, evidence on their effects before college is limited. We study a US Supreme Court ruling that reinstated AA in three states. Using nationwide SAT data, we separately identify positive effects of AA for Whites and underrepresented minorities. Using Texas administrative data, we find that AA narrowed racial gaps in grades, attendance, and college applications. Improvements in minorities' precollege human capital and college applications are concentrated in the top half of the test score distribution among the students for whom the policy most increases the returns to human capital investment.
