We use the duality in linear programming to solva the problem of optimal partnership contracts with moral hazards. We show the importance of allowing the partners to have partial distribution of revenue under some contingencies. An optimal contract maximizes production efficiency minus the loss...

We give an example to show that efficiency in the principal-agent organization depends on the public information nature of the wage contracts. When wage contracts are private, the principal may have a moral hazard problem in deviating from some of the contracts, and efficiency need not hold even...

We develop the theory of optimal auction design in a discrete bidding model. Examples show that many of the equivalence results or other well-known results may fail in an auction with discrete bidding. We show that the optimal auciton problem, however, has a similar solution. We formulate a...
