We explore the role of firms in insuring risk-averse workers. As a device that allows workers to commit to the delivery of their output, the firm arises endogenously as an alternative to the spot market if workers are sufficiently risk averse and the firm can base incentive payments on good...

We consider physicians with fixed capacity levels. If a physician's capacity exceeds demand, she may have an incentive to overtreat, i.e., she may provide unnecessary treatments to use up idle capacity. By contrast, with excess demand she may undertreat, i.e., she may not provide necessary...

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....

What are the welfare effects of a policy that facilitates for insurance customers to privately and covertly learn about their accident risks? We endogenize the information structure in Stiglitz's classic monopoly insurance model. We first show that his results are robust: For a small information...

We study a monopoly insurance model with endogenous information acquisition. Through a continuous effort choice, consumers can determine the precision of a privately observed signal that is informative about their accident risk. The equilibrium effort is, depending on parameter values, either...

Under contingent fees the attorney gets a share of the judgement; under conditional fees they get an upscale premium if the case is won, which is, however, unrelated to the adjudicated amount. We compare conditional and contingent fees in a framework where lawyers choose between a safe and a...

We consider successive generations of non-altruistic individuals carrying a good or bad gene. Daughters are more likely to carry their mother's gene than the opposite one. Competitive insurers can perform a genetic test revealing an agent's gene. They may condition their quotes on the agent's or...
