Regression Discontinuity in Serial Dictatorship: Achievement Effects at Chicago's Exam Schools
提出一种结合断点回归和倾向得分的实证策略，利用序列独裁机制中的准实验，估计芝加哥考试学校对学生学业成就的影响。
Many school and college admission systems use centralized mechanisms to allocate seats based on applicant preferences and school priorities. When tie-breaking uses non-randomly assigned criteria like distance or a test score, applicants with the same preferences and priorities are not directly comparable. The non-lottery setting does generate a kind of local random assignment that opens the door to regression discontinuity designs. This paper introduces a hybrid RD/propensity score empirical strategy that exploits quasi-experiments embedded in serial dictatorship, a mechanism widely used for college and selective K-12 school admissions. We use our approach to estimate achievement effects of Chicago's exam schools.
