In this Essay, Andrew Guzman proposes internationalization of antitrust law to supplant current methods of antitrust regulation across national borders. Specifically, instead of relying on local regulation, bilateral agreements between states, or a choice-of-law rule for antitrust enforcement, countries should adopt universal substantive standards. Moreover, Guzman recommends the World Trade Organization (WTO), which already employs a dispute resolution mechanism, as the governing forum for international antitrust issues. There, states can negotiate transfer payments in one international transaction to achieve agreement in another. Upon evaluating Professor Eleanor Fox’s proposal of a stand-alone World Competition Forum that would specialize exclusively in international antitrust negotiations, Guzman concludes that the WTO is the preferred forum. Its dispute resolution system would facilitate substantive cooperation among countries by allowing for concessions exchanged in antitrust as well as in other areas of international relations.
