Preserving Competition: Economic Analysis, Legal Standards and Microsoft

Abstract

In a recent symposium issue of the George Mason Law Review, Steven Salop and R. Craig Romaine use the Microsoft litigation as a focus for discussion of antitrust law. Salop and Romaine argue that each of the allegations against Microsoft could constitute evidence of a design by Microsoft to reduce competition and to preserve or extend monopoly power. They argue as well that the right legal standard to apply in monopolization cases is a competitive effects test that balances the benefits and harms of the monopolist's conduct. This article exposes problems with their approach, explains why it departs from current antitrust standards, and urges an approach consistent with current standards.
