The Effects of Affirmative Action Bans on College Enrollment, Educational Attainment, and the Demographic Composition of Universities
利用各州实施平权行动禁令的时间差异，研究发现禁令对普通学生和大学无显著影响，但会降低精英大学中少数族裔的入学比例，增加白人学生比例；加州案例显示禁令导致少数族裔学生从高选拔性校区流向低选拔性校区。
I estimate the effects of affirmative action bans on college enrollment, educational attainment, and college demographic composition by exploiting time and state variation in bans. I find that bans have no effect on the typical student and the typical college, but they decrease underrepresented minority enrollment and increase white enrollment at selective colleges. In addition, I use the case study methods of Abadie and Gardeazabal (2003) and Abadie, Diamond, and Hainmueller (2010) and find that the affirmative action ban in California shifted underrepresented minority students from more selective campuses to less selective ones at the University of California. © 2012 The President and Fellows of Harvard College and the Massachusetts Institute of Technology.
