Principal-agent models of moral hazard have been developed under the assumption that the principal knows the agent's risk-aversion. This Paper extends the moral hazard model to the case when the agent's risk-aversion is his private information, so that the model also exhibits adverse selection....

This paper describes the equilibrium of a discrete-time exchange economy in which consumers with arbitrary subjective discount factors and quasi-homothetic period utility functions follow linear Markov consumption and portfolio strategies. Explicit expressions are given for state prices and...
