Peer effects, financial aid and selection of students into colleges and universities: an empirical analysis
建立模型分析大学如何通过定价和资助政策最大化教育质量，发现学校质量分层明显，且高能力学生存在正同伴效应。
Abstract This paper develops a model in which colleges seek to maximize the quality of the educational experience provided to their students. We deduce predictions about the hierarchy of schools that emerges in equilibrium, the allocation of students by income and ability among schools, and about the pricing policies that schools adopt. The empirical findings of this paper suggest that there is a hierarchy of school qualities which is characterized by substantial stratification by income and ability. The evidence on pricing by ability is supportive of positive peer effects in educational achievement from high ability at the college level. Copyright © 2003 John Wiley & Sons, Ltd.
