Consider two agents who learn the value of an unknown parameter by observing a sequence of private signals. Will the agents commonly learn the value of the parameter, i.e., will the true value of the parameter become approximate common-knowledge? If the signals are independent and identically...

Technological progress is typically a result of trial-and-error research by competing firms. While some research paths lead to the innovation sought, others result in dead ends. Because firms benefit from their competitors working in the wrong direction, they do not reveal their dead-end...

How does the central bank's incentive to build a reputation affect speculators' ability to coordinate and the likelihood of the devaluation outcome during speculative currency crises? What role does market information play in speculators' coordination and the central bank's reputation building?...

This paper studies the aggregate consequences of individual learning in the labor market. Specifically, I examine this issue in a model of directed search on the job. Once matched, a firm-worker pair gradually learns the match-specific quality, taking the history of realized production as...

This note provides several generalizations of Mailath's (1987) result that incentive compatibility plus separation implies differentiability. The new results extend the theory to classic models in finance such as Leland and Pyle (1977), Glosten (1989), and De Marzo and Duffie (1999), that were...
