标题： The Direct and Spillover Effects of Large-scale Affirmative Action at an Elite Brazilian University

摘要： 我们考察了一项在巴西精英大学实施的平权行动政策，该政策为黑人和低收入学生保留了45%的入学名额。 我们发现，通过平权行动渠道入学的边缘录取学生在职业生涯早期的收入增加了14%。 但平权行动的实施也导致了大学中排名最高的学生的收入大幅下降。 我们提供的证据表明，对高排名学生成绩的负面溢出效应是由人力资本积累的减少和人脉价值的下降共同驱动的。 显示英文摘要

摘要： We examine the effects of an affirmative action policy at an elite Brazilian university that reserved 45 percent of admission slots for Black and low-income students. We find that marginally-admitted students who enrolled through the affirmative action tracks experienced a 14 percent increase in early-career earnings. But the adoption of affirmative action also caused a large decrease in earnings for the university's most highly-ranked students. We present evidence that the negative spillover effects on highly-ranked students' earnings were driven by both a reduction in human capital accumulation and a decline in the value of networking.
