Vertical Restraints under Asymmetric Information: On the Role of Participation Constraints

Abstract

We study a manufacturer-retailer relationship where, besides the adverse selection and moral hazard components, it is explicitly considered a type-dependent participation constraint capturing the shadow cost of exclusive dealings. The welfare effects of contracts based on both retail price and sales are compared to those of contracts contingent solely upon sales. When the type-dependent outside option severely aspects the agency problem and contracts are set non-cooperatively, retail price restrictions may be detrimental to consumers. At the same time, if contracts are set cooperatively, we show that whenever sales-based contracts are observed they are detrimental to consumers.asymmetric information, countervailing incentive, double marginalization, resale price maintenance, vertical restraint, welfare
