投入品价格歧视：零售努力溢出效应的作用
Input Price Discrimination: The Role of Retail Effort Spillovers
摘要
We investigate input price discrimination under secret contracting between a manufacturer and competing retailers, whose investment activities exhibit retail effort spillovers. We show that the economic effects of input price discrimination vary with the sign and magnitude of retail effort spillovers according to the contractual structure, namely, linear or two‐part tariffs. Retail effort spillovers and product differentiation affect the pass‐through of input price to retail quantity, which is defined under each contractual structure. Our analysis provides novel insights into the role of retail effort spillovers and into the evaluation of quantity pass‐through in the antitrust scrutiny of input price discrimination.
中文摘要
本文研究了制造商与竞争性零售商之间秘密合同下的投入品价格歧视问题，其中零售商的投资活动存在零售努力溢出效应。研究表明，投入品价格歧视的经济效应随零售努力溢出的正负及大小而变化，且这种变化取决于合同结构（线性关税或两部收费制）。零售努力溢出与产品差异化会影响投入品价格向零售数量的传导效应，该传导效应在不同合同结构下具有不同定义。本文分析为理解零售努力溢出的作用机制，以及反垄断审查中评估数量传导效应对投入品价格歧视的影响提供了全新视角。
