Transnational Antitrust Law
In light of the significant diversity that remains among legal systems regarding the purpose and substance of market regulation, it is no surprise that efforts to develop a body of international antitrust law have failed. Instead, we rely on a diverse set of norms and transnational practices to regulate the increasingly globalized economy. This chapter discusses those practices, focusing on the actors and institutions involved. Section II addresses the production of substantive antitrust law at different levels (national, regional, and international) and discusses some of the ways in which these norms spread across legal systems. Section III turns to mechanisms for improving cooperation among legal systems in the enforcement of divergent regulatory norms, as well as to continuing sites of contestation among regimes. Section IV concludes with an analysis of the prospects for increased convergence in the field of antitrust law and policy.
