This short paper proves the following conjecture of D. Bouyssou: a preference aggregation function built by iteration of a strictly monotonic and symmetric social choice correspondence cannot be strictly monotonic. Received: 1 October 1998/Accepted: 23 December 1999     

Calibrated Incentive Contracts

This paper studies a dynamic agency problem which includes limited liability, moral hazard, and adverse selection. The paper develops a robust approach to dynamic contracting based on calibrating the incentive properties of simple benchmark contracts that are attractive but infeasible, due to limited liability constraints. The resulting dynamic contracts are detail‐free and satisfy robust performance bounds independently of the underlying process for returns, which need not be i.i.d. or even ergodic.
