Abstract

Monopolization, in the United States, and abuse of dominance, in the European Union, embody different philosophies about how best to police single firm conduct in competition law. Surprisingly, their disagreement ends at market definition. Both doctrines define relevant markets by similar processes and use relevant markets for similar purposes. In some contexts, this type of agreement would be a welcome sight. Here, it reflects a pocket of confusion in each area of law. This chapter describes the confusion of current market definition practices and takes some initial steps toward a more coherent approach.

Keywords: market definition, relevant market, monopoly, monopolization, abuse of dominance, abuse of a dominant position
