The literature on voluntary provision of public goods includes recent theoretical work on the formation of voluntary coalitions to provide public goods. Theory is ambiguous on the equilibrium coalition size and contribution rates. We examine the emergence of coalitions, their size, and how...

In SIR models, infection rates are typically exogenous, whereas individuals adjust their behavior in reality. City-level data across the globe suggest that mobility falls in response to fear, proxied by Google searches. Incorporating experimentally validated measures of social preferences at the...

Coordination is central to social interactions. Theory and conventional lab experiments suggest that cheap talk/communication can enhance coordination under certain conditions. Two aspects that remain underexplored are (1) the interaction between the number of players (group size) and...

We study the role of commitment in communication and its interactions with rules, which determine whether or not information is verifiable. Our framework nests models of cheap talk, information disclosure, and Bayesian persuasion. Our model predicts that commitment has opposite effects on...

Deferred Acceptance (DA), a widely implemented algorithm, is meant to improve allocations: under classical preferences, it induces preference-concordant rankings. However, recent evidence shows that—in both real, large-stakes applications and experiments—participants frequently play...

This paper uses laboratory experiments to directly test a central prediction of disclosure theory: that strategic forces can lead those who possess private information to voluntarily provide it. In a simple two-person disclosure game, we find that senders disclose favorable information, but...
