I prove an efficiency result for repeated games with imperfect public monitoring in which one player's utility is privately known and evolves according to a Markov process. Under certain assumptions, patient players can attain approximately efficient payoffs in equilibrium. The public signal...

We study a dynamic trading game in which the information asymmetry between the agents develops over time. A seller and potential buyers start out symmetrically uninformed about the quality of a good, but the seller becomes informed after the game begins. We show that this developing adverse...

Many service industries, including the medical and legal professions in some countries, display a gated structure. Rather than approaching a final producer directly, a consumer will first seek a referral from an intermediary. In this paper, we provide one possible explanation for such an...

We allow buyers to choose the timing of offers in a dynamic adverse selection model with a single seller. Buyers have private information and can delay their one-time private offers to learn from other buyers by observing trading behavior. We find that the equilibrium exhibits maximum delay in...
