VIRTUAL EVENT: The value of a peer
17 March 2021, 1:00 pm–2:00 pm
In this webinar, Ingo Isphording will discuss peer value-added, a new approach to quantify the total contribution of an individual peer to student performance.
This event is free.
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, Ingo and his co-author 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.
