Network Formation and Peer Effects: Connecting Two Strands of Literature

Revue économique, 2022, vol. 73, issue 5, 669-681

Abstract: In this review paper we make the point that the literature on social interactions needs to integrate much more tightly the study of the network formation process and the analysis of peer effects, both theoretically and empirically. We also provide some descriptive evidence from a sample of students in higher education that is suggestive of forward-looking behaviour in the choice of study partners. Students appear to have homophilic preferences along ability measures, both conditional and unconditional on other traits that are not directly related to ability. Such homophilic preferences are substantially more pronounced among the most able students. JEL Codes: D85, C15, C73, C63, I23.
