Agents face a coordination problem akin to the adoption of a network technology. A principal announces investment subsidies that, at minimal cost, attain a given likelihood of successful coordination. Optimal subsidies target agents who impose high externalities on others and on whom others...

This paper develops a learning model of cultural change to investigate why women's labor force participation (LFP) and attitudes toward women’s work both changed dramatically. In the model, women's beliefs about the long-run payoff from working evolve endogenously via an intergenerational...

Individuals must often choose among discrete actions with imperfect information about their payoffs. Before choosing, they have an opportunity to study the payoffs, but doing so is costly. This creates new choices such as the number of and types of questions to ask. We model these situations...
