Market power and inefficiency: a contracts perspective
从契约理论视角综述市场势力的经济学,讨论价格歧视、捆绑销售、纵向整合等实践对利润最大化的约束,以及反竞争行为的动机。
This paper surveys the economics of market power from the perspective of contract theory. Various practices that might be of competition policy concern including price discrimination, quantity discounts, bundling, vertical integration, and contracts with customers -- are discussed in terms of constraints on profit maximization, chiefly arising from incomplete information and credible commitment problems. First, the exploitation of pure monopoly power over final consumers or downstream, firms is discussed. Then motives for anticompetitive behavior towards rival firms are considered, including avoidance of profit dissipation, extraction of rival surplus, and exploitation of customer disunity.
