A new approach to moral hazard is presented. Once local incentive compatibil- ity is satis?ed, the problem of verifying global incentive compatibility is shown to be isomorphic to the problem of comparing two classes of distribution functions. Thus, tools from choice under uncertainty can be...

This paper provides a complete characterization of optimal contracts in principal-agent settings where the agent's action has persistent effects. We model general information environments via the stochastic process of the likelihood-ratio. The martingale property of this performance metric...

We show that prices and incentives recommended by the salesforce literature when targeting a profitable segment can attract unprofitable customers, particularly when salespeople have high productivity and low risk (i.e., risk aversion times uncertainty). Therefore, when customers are...
