本文使用一个独特的数据集来测量大学室友之间的同伴效应。达特茅斯学院大一的室友和室友是随机分配的。我发现同龄人对平均成绩和加入兄弟会等社会团体的决定有影响。在其他重大的人生决策中，如选择大学专业，明显缺乏居住同伴效应。GPA的同伴效应发生在单个房间的水平，而兄弟会成员的同伴效应发生在房间和整个宿舍的水平。总体而言，数据提供了强有力的证据，同伴效应的存在，学生的成果。
This paper uses a unique data set to measure peer effects among college roommates. Freshman year roommates and dormmates are randomly assigned at Dartmouth College. I find that peers have an impact on grade point average and on decisions to join social groups such as fraternities. Residential peer effects are markedly absent in other major life decisions such as choice of college major. Peer effects in GPA occur at the individual room level, whereas peer effects in fraternity membership occur both at the room level and the entire dorm level. Overall, the data provide strong evidence for the existence of peer effects in student outcomes.
