We develop a model in which large risk-neutral firms and individual risk-averse consumers compete to employ heterogeneous workers by posting compensation menus. Production takes time, and we analyze how screening motives interact with the desire to smooth consumption. There is a unique symmetric...

We propose a parsimonious model with adverse selection where delinquency, renegotiation, and bankruptcy all occur in equilibrium as a result of a simple screening mechanism. A borrower has private information about her cost of bankruptcy, and a lender may use random contracts to screen different...

Market based instruments are proving e¤ective in biodiversity procure- ment and in the management of regulatory schemes to preserve biodiversity. The design of these schemes brings together issues in auction design, con- tract theory, ecology, and monitoring. Using a mixed adverse selection,...

This paper examines uberrimae fidei (utmost good faith) with adverse selection in an insurance market. If consumers know their risk type (they know their expected loss), and if they understand the concept of uberrimae fidei, adverse selection is completely eliminated. However, if uberrimae fidei...

We consider an exchange economy in which a seller can trade an endowment of a divisible good whose quality she privately knows. Buyers compete in menus of non-exclusive contracts, so that the seller may choose to trade with several buyers. In this context, we show that an equilibrium always...

Consider a seller of a divisible good, facing several identical buyers. The quality of the good may be low or high, and is the seller's private information. The seller has strictly convex preferences that satisfy a single-crossing property. Buyers compete by posting arbitrary menus of contracts....

We consider a general economy, where agents have private information about their types. Types can be multi-dimensional and potentially interdependent. We show that, if the interim distribution of types is common knowledge (the exact number of agents for each type is known), then a mechanism...

This paper studies markets plagued with asymmetric information on the quality of traded goods. In Akerlof's setting, sellers are better informed than buyers. In contrast, we examine cases where buyers are better informed than sellers. This creates an inverse adverse selection problem: The market...

This paper applies recent results and advances in the field of ambiguity theory to adverse selection in a delegation process. Our results are the following ones: i) a relevant second-best contract induces no production distortion considering the efficient agent. This alike to the standard case....
