The Effect of Classmate Characteristics on Post-Secondary Outcomes: Evidence from the Add Health
利用校内跨年级设计，发现高中同学中母亲受过大学教育的比例增加会降低辍学率并提高大学入学率，但对在校成绩、态度和行为无显著影响；弱势少数族裔同学比例对高中后结果无直接影响，但会降低师生关系质量并增加不良行为。
This paper uses a within-school/across-cohort design to present new evidence of the effects of high school classmate characteristics on a wide range of post-secondary outcomes. We find that increases in the percent of classmates with college-educated mothers decreases the likelihood of dropping out and increases the likelihood of attending college, despite showing no impact on a range of in-school achievement, attitudes, and behaviors. The percent of students from disadvantaged minority groups does not show any effects on post-secondary outcomes, but is associated with students reporting less caring student-teacher relationships and increased prevalence of some undesirable student behaviors during high school.
