Abstract
This article examines how antitrust law and policy can benefit from ideas developed in the academic strategy field. Because accurate assessment and prediction of the effects of firm conduct depend in part on understanding individual firm capabilities, knowledge from the strategy field and other business fields complements the contributions from industrial organization economics (IO). These business fields also offer theoretical and empirical challenges to the IO paradigm, which dominates antitrust analysis. The article begins with a comparison between strategy and IO and then illustrates how the strategy field can contribute to antitrust merger analysis. The article then assesses the influence of the strategy field on antitrust law and scholarship based on a citation analysis, which reveals little evidence of influence. It concludes with an examination of the likely impediments to the diffusion of strategy field ideas into antitrust.
