Rothschild and Stiglitz (1976) show that there need not exist a competitive equilibrium in markets with adverse selection. Building on their framework we demonstrate that externalities between agents - an agent's utility upon accepting a contract depends on the average type attracted by the...

We analyze competitive credit markets with asymmetric information in which borrowers seek financing for either positive or negative net present value projects. The striking result is that there always exists an equilibrium where investment is efficient, while competitive lenders make strictly...

This paper studies general markets with adverse selection in which symmetric firms supply (potentially multiple) products to privately-informed consumers and compete with price schedules. I show that a basic price cap regulation, in which the price caps are endogenously determined by firms,...

A seller of a divisible good faces 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 menus of nonexclusive contracts, so that...

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 study optimal non-linear contracts offered by two firms competing for the exclusive services of workers, who are privately informed about their ability and motivation. Firms differ in their organizational form, and motivated workers are keen to be hired by the non-profit firm because they...

Riley (1979)'s reactive equilibrium concept addresses problems of equilibrium existence in competitive markets with adverse selection. The game-theoretic interpretation of the reactive equilibrium concept in Engers and Fernandez (1987) yields the Rothschild-Stiglitz (1976)/Riley (1979)...
