Perfect and Imperfect Real-Time Monitoring in a Minimum-Effort Game

This paper presents the results from a minimum-effort game in which individuals can observe the choices of others in real time. We find that under perfect monitoring almost all groups coordinate at the payoff-dominant equilibrium. However, when individuals can only observe the actions of their immediate neighbors in a circle network, monitoring improves neither coordination nor efficiency relative to a baseline treatment without real-time monitoring. We argue that the inefficiency of imperfect monitoring is due to information uncertainty, that is, uncertainty about the interpretation of the information available regarding the actions of others.
