Bandits in the lab

Johannes Hoelzemann, Nicolas Klein

Abstract



We experimentally implement a dynamic public‐good problem, where the public good in question is the dynamically evolving information about agents' common state of the world. Subjects' behavior is consistent with free‐riding because of strategic concerns. We also find that subjects adopt more complex behaviors than predicted by the welfare‐optimal equilibrium, such as noncut‐off behavior, lonely pioneers, and frequent switches of action.
