When the U.S. Supreme Court overturned its century-old precedent that treated resale price maintenance (RPM) as a per se violation of the antitrust laws, it signaled approval for the vertical restraint’s widespread use. But the increased use of RPM occurred under a pre-existing rule that permitted RPM as long as no formal agreement over price was reached. This paper documents not only the increased use of RPM post Leegin but also the importance of avoiding the appearance of agreements to control resale prices. The paper then discusses how plaintiffs, previously enamored of claims of RPM, are now recasting vertical RPM arrangements as ancillary to horizontal agreements among distributors that are made effective though enforcement by producers.  相似文献

The legal framing of a firm’s pricing strategy can determine whether it constitutes online resale price maintenance (RPM) or online most favored nation (MFN). Together, cases that involve online RPM and MFN can be viewed as a natural experiment of how antitrust economics and law may adapt to an online world. Thus far, legal theories that have been inconsistent with economic theories have dictated enforcement across jurisdictions, which has led to confusion that thwarts potentially efficient business practices. This paper distinguishes issues of online RPM from traditional RPM and online RPM from online MFN. We apply the economics learning to RPM and analyze the antitrust cases of online RPM and MFN to date in the United States, Europe, and Australia. Finally, we offer policy recommendations that reduce the confusion in current legal doctrine.  相似文献

We consider a model in which firms use resale price maintenance (RPM) to dampen competition. We find that even though the motive for using RPM is thus anti-competitive, market forces may limit the overall adverse impact on consumers. Indeed, we find that when there are a large number of firms in the market, consumer welfare under a laissez-faire policy might be as high or almost as high as it would be under an alternative policy in which RPM is banned. Government interventions that put an upper limit on the extent of industry-wide adoption of RPM can have adverse welfare effects in the model. We further show that proposed guidelines in the United States and Europe may come close to minimizing welfare.  相似文献

The Supreme Court’s reasoning in Leegin turned on the insight that manufacturers may use resale price maintenance (RPM) for procompetitive purposes. This paper presents a model of manufacturer-retailer interactions that clarifies why, as a rule, retailers and manufacturers are joint beneficiaries of service-inducing RPM. The model identifies factors that determine how RPM-generated benefits are allocated between a manufacturer and its retailers. The paper then shows that manufacturers may use market share discounts (MSD) in lieu of RPM or other vertical restraints to induce retailer performance. The outcomes and efficiency effects that are achieved with RPM can be replicated and usually surpassed if manufacturers substitute MSD for RPM, thereby enabling a manufacturer to retain all incremental profit rather than conceding some of it to retailers.  相似文献

This paper examines the competition and welfare effects of vertical price fixing through industry-wide resale price maintenance (RPM) arrangements, such as those benefiting from exemption from a general prohibition against RPM. A bilateral oligopoly framework is employed incorporating differentiation between manufacturer products and between retailer services. Transactions between the stages involve prices being determined through bargaining. We do not find RPM to be universally undesirable. However where retailer power is strong, the social effects of RPM are likely to be adverse, since the practice can assist in coordinating final price levels and prevent socially desirable countervailing power arising.  相似文献

A manufacturer's choice between resale price maintenance (RPM) and exclusive territories to protect dealer provided services is examined empirically. The relative efficacy of RPM in solving the free rider problem depends on the life cycle of the product being distributed. A manufacturer of a product with a long life cycle is more likely to protect its dealers' investment in service with exclusive territories, whereas RPM becomes the more probable restraint for products of short life spans. Data gleaned from vertical restraint litigation strongly support this hypothesis.The author wishes to thank Howard P. Marvel, Laura A. Boyd, and two anonymous referees for comments on earlier versions of this paper. The financial support of The Procter and Gamble Fund is also gratefully acknowledged.

This paper explores the economic roles of resale price maintenance (RPM) in supply chains for a specific product, when consumers have taste heterogeneity and the manufacturer faces demand uncertainty. Two transaction schemes within supply chains are compared: (1) RPM, and (2) decentralized pricing in a competitive market environment. With decentralized pricing, a manufacturer loses the incentive to produce a product in categories where the probability that the manufacturer fails to design the product as suitable to public tastes of consumers is high. However, RPM resolves the problem and induces the manufacturer to supply the good, bringing positive surplus to consumers.  相似文献

A decade ago, Leegin overruled Dr. Miles and subjected RPM to rule-of-reason treatment, under which the potential for anticompetitive conduct should be analyzed (rather than automatically assumed to be present). In its Leegin decision, the Supreme Court identified four ways in which RPM could be used to retard competition and consequently reduce consumer welfare: The first two involve the well-known concerns that RPM could be used to support either a manufacturer cartel or a dealer cartel; the last two involve unilateral conduct designed to foreclose entry or hinder smaller rivals. In this paper, we analyze these potentially harmful uses of RPM. We conclude that RPM does not pose a substantial anticompetitive threat.  相似文献
