Trading dynamics in decentralized markets with adverse selection
We study a dynamic, decentralized market environment with asymmetric information and interdependent values between buyers and sellers, and characterize the complete set of equilibria. The model delivers a stark relationship between the severity of the information frictions and the time it takes for the market to clear, or market liquidity. We use this framework to understand how asymmetric info...
متن کاملWorking Paper No. 11-36 Trading Dynamics in Decentralized Markets with Adverse Selection
We study a dynamic, decentralized lemons market with one–time entry and characterize its set of non–stationary equilibria. This framework offers a theory of how a market suffering from adverse selection recovers over time endogenously; given an initial fraction of lemons, the model provides sharp predictions about how prices and the composition of assets evolve over time. Comparing economies in...
متن کاملContinuous Time Trading in Markets with Adverse Selection
We investigate the nature of the adverse selection problem in a market for a durable good where trading and entry of new buyers and sellers takes place in continuous time. In the continuous time model equilibria with properties that are qualitatively different from the static equilibria, emerge. Typically, in equilibria of the continuous time model sellers with higher quality wait in order to s...
متن کاملMatching markets with adverse selection
This paper considers a market with adverse selection in the spirit of Rothschild and Stiglitz (Quart. J. Econ. 90 (1976) 629). The major departure from existing approaches is that we model a decentralized market that is open-ended and constantly refilled by new participants, e.g., by new workers and firms in the case of a labor market. The major novelty of this approach is that the distribution...
متن کاملOptimal Interventions in Markets with Adverse Selection
1 Akerlof (1970) shows how asymmetric information can create adverse selection and undermine market efficiency. Economic and legal institutions, such as auditors, underwriters, accountants, or used-car dealers, often emerge to limit adverse selection and allow markets to function. As a result, direct government interventions are usually unnecessary. If a market does collapse, however—presumably...
