    Abstract of the keynote address: 

    Size Matters: Cross-Border Competitive Harm and Non-Major Markets

    Despite substantial growth in international commerce over the last few decades international community did not develop a way of dealing with transnational anticompetitive activities. Competitive processes are governed predominantly by domestic and sometimes (when in existence and operational) regional laws. This necessitates their extraterritorial application, in appropriate cases, to preserve competitive processes and to protect domestic consumers from competitive harm inflicted from abroad. While extraterritoriality was spearheaded in competition law and became ubiquitous over time, its development and embracing did not make the approach easier and more accessible. The emergence of a variety of cooperative instruments—be it agreements between jurisdictions or virtual networks—while extremely helpful, neither addressed a range of existing legal and practical hindrances, nor enabled to deal with notable power imbalances between the major markets and other systems. The existing challenges of cross-border cases make their pursuit a particularly uphill battle for the latter, often less economically and/or politically affluent. They experience these issues differently, while often—on top of these—operating in a broader context of difficult circumstances and notable capacity constraints. In effect, they are particularly vulnerable to being victims of cross-border competitive harm. This contribution aims to fill an existing gap in our understanding of the position of non-major markets in such situations and to offer a manageable law and policy recommendations on how to navigate this sub-optimal, if not, adverse system of global governance.
