How Chicago Economics Distorts “Consumer Welfare” in Antitrust

Abstract

Since the publication of Robert Bork’s The Antitrust Paradox, lawyers, judges, and many economists have defended “consumer welfare” (CW) as a standard for decisions about antitrust goals and enforcement priorities. This article argues that the CW is actually an empty concept and is an inappropriate goal for antitrust. Judge Bork adopted CW from economics where welfare unambiguously measured utility or well-being. Welfare economists concede that there is no credible measurable link between price and output and human well-being. This means that the concept of CW does not legitimate limited antitrust enforcement nor does it justify the exclusion of other antitrust goals that require more active enforcement practices. This article contends that antitrust policy is not welfare based at all and, that if it were, antitrust policy and enforcement would differ significantly from the Chicago School vision. Without the fiction that economists can establish that in the short run lower price and higher output measurably increase welfare more than other goals, recent defenses of the CW standard resolve down to arguments based on unsupported assumptions.
