Francesca Foliano

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.
