Peer effects at campus cafeterias


  • Matteo Ploner



This study investigates the voluntary allocation of monetary resources to future food consumption by customers of campus cafeterias. A rich dataset allows us to infer social proximity of cafeteria customers and to measure social spillovers in allocation decisions. We show that individuals tend to imitate directly observed behavior and that close social proximity further encourages imitation. Copyright Springer-Verlag 2013
