Geographic variations in a model of physician treatment choice with social interactions
Location-specific norms of behavior are a widespread phenomenon. In the case of medical practice, numerous studies have found that geographic location exerts a strong influence on the choice of treatments and procedures. This paper shows how the presence of social influence on treatment decisions can help to explain this phenomenon. We construct a theoretical model in which physicians' treatment choices depend on patients' characteristics and on the recent choices of nearby peers - either because there are local knowledge spillovers or because physicians want to conform to local practice ...

Contracts with social multipliers
We develop a model of contracting in which individual effort choices are subject to social pressure to conform to the average effort level of others in the same risk-sharing group. As in related models of social interactions, a change in exogenous variables or contract terms generates a social multiplier. In this environment, small differences in fundamentals such as skill or effort cost can lead to large differences in group productivity. We characterize the optimal contract for this environment and describe the properties of equilibria, properties that agree with stylized facts on effort ...
