Abstract

This master's thesis examines European competition policy in digital markets, with particular emphasis on the application of Article 102 TFEU to cases of abuse of dominant position in the context of modern digital platforms. The emergence of large digital platforms and the development of powerful digital ecosystems have given rise to new forms of economic power associated with network effects, data concentration, economies of scale and user lock-in mechanisms. These developments have created significant challenges for the application of EU competition law and, in particular, for addressing abusive conduct in digital markets. Against this background, the thesis explores whether the existing framework of EU competition law and the traditional mechanisms for addressing abuse of dominance are capable of responding to the distinctive characteristics of digital markets. It further investigates how the experience gained through the application of these rules has contributed to the gradual evolution of the European regulatory approach and to the expansion of the EU legislator’s regulatory toolkit, both through new regulatory interventions and through the development of economic and methodological tools tailored to the realities of the digital economy. To this end, the thesis analyses the theoretical foundations of European competition policy, the concepts of dominance and abuse of dominance and the distinctive economic characteristics of digital markets. It also examines the relevant case law of the European Commission and the Court of Justice of the European Union through landmark cases involving major digital platforms, including Google and Apple. The methodology adopted is based on the analysis of EU legislation, case law, competition law scholarship and the economic literature on digital markets. By combining legal and economic perspectives, the thesis seeks to address the challenges arising from the operation of digital markets and to demonstrate how the European Union is gradually adapting its regulatory instruments to the particularities of the digital economy. In this regard, particular attention is paid to the objective of safeguarding effective competition, reducing distortions associated with the market power of digital gatekeepers and enhancing user protection. Finally, the thesis presents conclusions and critical observations regarding the gradual transition of the European Union from a predominantly ex post model of competition law enforcement towards a more comprehensive and preventive framework for the regulation of digital markets. It further assesses the role that these emerging instruments are expected to play in addressing the challenges posed by the digital economy.
