This paper studies competitive equilibria in economics characterized by the presence of asymmetric information (both of the moral hazard and the adverse selection type). We consider economies where non-exclusive contracts (securities) with payoffs dependent on the agents' private information are...

This paper studies competitive equilibria in economies characterized by the presence of asymmetric information, where non-exclusive contracts with payoffs dependent on the agents' private information are traded on competitive markets. For such economies competitive equilibria may not exist with...

This paper studies equilibria for economies characterized by moral hazard (hidden action), in which the set of contracts marketed in equilibrium is determined by the interaction of financial intermediaries. The crucial aspect of the environment that we study is that intermediaries are restricted...

Economies with asymmetric information are encompassed by an extension of the model of general competitive equilibrium that does not require an explicit modeling of private information. Sellers have discretion over deliveries on contracts; this is in common with economies with default, incomplete...
