Type 1 Error and Uncertainty: Holding the Antitrust Enforcement Pendulum Steady
Posted by D. Daniel Sokol
Jim Rill (Howrey) & Thomas Dillickrath (Howrey) explain Type 1 Error and Uncertainty: Holding the Antitrust Enforcement Pendulum Steady.
ABSTRACT: Recent pronouncements by the leaders of the federal antitrust agencies have brought into sharper focus the debate over how best to balance the risks of Type 1 error (or over-enforcement error) against the risks of Type 2 error (or under-enforcement error) in antitrust enforcement. In this paper, we examine the literature surrounding the debate and suggest that the harm resulting from Type 1 error more likely and more often exceeds that stemming from Type 2 error. Indeed, the Supreme Court has recognized this imbalance in its antitrust jurisprudence, repeatedly insisting on rules that give more weight to avoiding over-deterrence of procompetitive conduct.
Especially in the area of single-firm conduct analyzed under Section 2 of the Sherman Act or Section 5 of the FTC Act, the dangers of overly interventionist antitrust rules are not limited to actual government enforcement and private actions that lead to punishing and enjoining procompetitive conduct. Such rules create uncertainty and fear resulting in constructive Type 1 error; that is, businesses forego aggressive competition that benefits consumers for fear of becoming embroiled in government or private enforcement actions. These threats to consumer welfare are compounded by amorphous antitrust rules that make it impossible for businesses to know ex ante whether their conduct will be deemed violative of the antitrust laws. Such legal ambiguity can deter businesses from engaging in efficient, procompetitive conduct; even conduct that would ultimately be found to be legal.

Antitrust policy over the last 25 years can claim substantial achievements: the stated terms of the debate have shifted to consumer welfare and efficiency; the 1982 and subsequent Merger Guidelines and the Hart-Scott-Rodino review process provide safe havens, comparative predictability, and effective protection against suits filed after a deal is done; and large-firm monopolization cases have become less frequent, though the Microsoft case represents a notable exception.
