对教育环境中的同伴效应的研究面临两个主要问题。首先是内生分类的存在，它混淆了社会影响和社会选择对个人成就的影响。第二个问题是如何解释本地网络依赖关系，通过这些依赖关系，对等效应会影响个体行为。我们使用关于全日制研究生项目学生之间的学习成绩、友谊和寻求建议关系的纵向数据来经验性地解决这些问题。我们指定了基于随机代理的模型，该模型允许估计社会选择和社会影响对个人绩效的相互依赖的贡献。我们报告了同伴效应的证据。学生倾向于吸收他们朋友和导师的平均表现。与此同时，学业成绩相近的学生更有可能发展友谊和建议关系。总而言之，这些结果表明，社会影响和社会选择的过程是一个更一般的、将网络结构和个人行为联系在一起的共同进化过程的子组成部分。我们讨论了我们的发现和当前教育经济学和社会学研究之间可能的接触点。
Studies of peer effects in educational settings confront two main problems. The first is the presence of endogenous sorting which confounds the effects of social influence and social selection on individual attainment. The second is how to account for the local network dependencies through which peer effects influence individual behavior. We empirically address these problems using longitudinal data on academic performance, friendship, and advice seeking relations among students in a full-time graduate academic program. We specify stochastic agent-based models that permit estimation of the interdependent contribution of social selection and social influence to individual performance. We report evidence of peer effects. Students tend to assimilate the average performance of their friends and of their advisors. At the same time, students attaining similar levels of academic performance are more likely to develop friendship and advice ties. Together, these results imply that processes of social influence and social selection are sub-components of a more general a co-evolutionary process linking network structure and individual behavior. We discuss possible points of contact between our findings and current research in the economics and sociology of education.
