The Value of a Peer

FBK-IRVAPP is pleased to invite you to the following seminar: The Value of a Peer.

With the participation of Ingo E. Isphording

Language The seminar is held in English.

Abstract This paper introduces peer value-added, a new approach to quantify the total contribution of an individual peer to student performance. Peer value-added captures social spillovers irrespective of whether they are generated by observable or unobservable peer characteristics. Using data with repeated random assignment to university sections, we find that students significantly differ in their peer value-added. Peer value-added is a good out-of-sample predictor of performance spillovers in newly assigned student-peer pairs. Yet, students’ own past performance and other observable characteristics are poor predictors of peer value-added. Peer value-added increases after exposure to better peers, and valuable peers are substitutes for low-quality teachers.

The seminar will be held on the web conference platform Google meet.
