This study explores mechanism design for networks of interpersonal relationships. Agents' social (i.e., altruistic or spiteful) preferences and private payoffs are all subject to asymmetric information; utility is (quasi-)linear, types are independent. I show that any network of at least three...

Social preferences facilitate the internalization of health externalities, for example by reducing mobility during a pandemic. We test this hypothesis using mobility data from 258 cities worldwide alongside experimentally validated measures of social preferences. Controlling for time-varying...

Externalities and social preferences, such as patience and altruism, play a key role in the endogenous choice of social interactions, which in turn affect the diffusion of a pandemic or patterns of social segregation. We build a dynamic model, augmented with an SIR block, in which agents...

People trade favors when doing so increases efficiency. Will they when it reduces efficiency, such as in political logrolling? We introduce the "Stakeholder Public Bad" game, in which common fund contributions increase one person’s earnings (the "Stakeholder") while reducing others'...

People have been shown to engage in favor-trading when it is efficiency-enhancing to do so. Will they also trade favors when it reduces efficiency, as in a series of wasteful public projects that each benefits an individual? We introduce the “Stakeholder Public Bad” game to study this...

Many consumers care about climate change and other externalities associated with their purchases. We analyze the behavior and market effects of such "socially responsible consumers" in three parts. First, we develop a flexible theoretical framework to study competitive equilibria with rational...
