We provide several generalizations of Mailath's (1987) result that in games of asymmetric information with a continuum of types incentive compatibility plus separation implies differentiability of the informed agent's strategy. The new results extend the theory to classic models in finance such...

We study non-stationary dynamic decentralized markets with adverse selection in which trade is bilateral and prices are determined by bargaining. Examples include labor markets, housing markets, and markets for financial assets. We characterize equilibrium, and identify the dynamics of...

We study learning in a decentralized pairwise adverse selection economy, where buyers have access to the quality of traded goods but not to the quality of non- traded goods. Buyers categorize ask prices in order to predict quality as a function of ask price. The categorization is endogenously...

We relax the common assumption of homogeneous beliefs in principal-agent relationships with adverse selection. Principals are competitors in the product market and write contracts also on the base of an expected aggregate. The model is a version of a cobweb model. In an evolutionary learning...

The health care industry in some countries displays a gated structure. Rather than approaching a specialist directly, a patient will first seek a referral from a general practitioner. We provide one possible explanation for such an industry structure. If the outcome of treatment depends on the...

We study market dynamics when an owner learns over time about the quality of her asset. Since this information is private, the owner sells strategically to a less informed buyer following sufficient negative information. In response, market prices feature a "U-shape" relative to the length of...

We present a dynamic model of trading under adverse selection in which a seller sequentially meets buyers, each of whom receives a noisy signal about the quality of the seller's asset and offers a price. We fully characterize the equilibrium trading dynamics and show that buyers' beliefs about...

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...

We relax the common assumption of homogeneous beliefs in principal-agent relationships with adverse selection. In an evolutionary learning set-up, which is imitative, principals can have different beliefs about the distribution of agents' types in the population. The resulting nonlinear dynamic...
