We develop a model of assignment games with pairwise-identitydependent externalities. A concept of conjectural equilibrium is proposed, and the universal conjecture is shown to be the necessary and sufficient condition for the general existence of equilibrium. We then apply the solution concept...

We analyze optimal labor contracts when the worker is inequity averse towards the employer. Welfare is maximized for an equal sharing rule of surplus between the worker and the firm. That is, profit sharing is optimal even if effort is contractible. If the firm can make a take-it-or leave-it...

We examine that the bilateral supplier affects the incentive contracts that owners of retailers offer their managers. Thus, we compare the two models: (1) decentralized bargaining between manufacturers and retailers including two-part tariff contract (2) linear input pricing without bargaining....
