Refusal to Deal and Investment in Product Quality

Author

  • Stephen Martin

Abstract

Recent U.S. Supreme Court decisions have taken the views that monopoly profit is "incentive to innovate" and that obliging a vertically-integrated antitrust monopolist to deal with downstream rivals may lessen the incentive for the monopolist, the rival, or both to invest in ...economically beneficial facilities." In a model of endogenous product quality, refusal to deal increases the payoff of the integrated firm and reduces equilibrium investment in quality, consumer surplus, and net social welfare if varieties are moderate or good substitutes. If varieties are poor substitutes, the integrated firm maximizes its payoff setting a wholesale price that allows the downstream rival a small economic profit.
