regulation, and multiproduct pricing, can be naturally formulated as an MPEC<br />
or an EPEC. In Chapter 5, we present a novel MPEC approach for computing<br />
solutions of the static moral-hazard problem. We consider deterministic contracts<br />
as well as contracts <strong>with</strong> action and/or compensation lotteries, and formulate each<br />
case as an MPEC. We investigate and compare solution properties of the MPEC<br />
approach to those of the linear programming (LP) approach <strong>with</strong> lotteries. We<br />
propose a hybrid procedure that combines the best features of both. The hybrid<br />
procedure obtains a solution that is, if not global, at least as good as an LP<br />
solution. It also preserves the fast local convergence property by applying an<br />
SQP algorithm to MPECs. Numerical results on an example show that the hybrid<br />
procedure outperforms the LP approach in both computational time and solution<br />
quality in terms of the optimal objective value.
