Recent studies on competition law and digital markets reveal that accumulating personal information through data collection and acquisition methods benefits consumers considerably. Free of charge, fast and personalised services and products are offered to consumers online. Collected data is now an indispensable part of online businesses to the point that a new economy, a data-driven sector, has emerged. Many markets such as the social network, search engine, online advertising and e-commerce are regarded as data-driven markets in which the utilisation of Big Data is a requisite for the success of operations. However, the accumulation and use of data brings competition law concerns as they contribute to market power in the online world, resulting in a few technology giants gaining unprecedented market power due to the Big Data accumulation, indirect network effects and the creation of online ecosystems. As technology giants have billions of consumers worldwide, data-driven markets are truly global. In these data-driven markets, technology giants abuse their dominant positions, but existing competition law tools seem ineffective in addressing market power and assessing abusive behaviour related to Big Data. This book argues that a novel approach to the data-driven sector must be developed through the application of competition law rules to address this. It argues that current and potential conflicts can be mitigated by extending the competition law assessment beyond the current competition law tools to offer a modernised and unified approach to the Big Data–related competition issues. Promoting new legal tests for addressing the market power of technology giants and assessing abusive behaviour in data-driven markets, this book advocates for cooperation between competition and data protection authorities. It will be of interest to students, academics and practitioners with an interest in competition law and data protection.

This book addresses the question of how competition authorities assess mergers in the Information Communication Technology (ICT) sector so as to promote competition in innovation. A closer look at the question reveals that it is far more complex and difficult to answer for the ICT, telecommunications and multi-sided platform (MSP) economy than for more traditional sectors of the economy. This has led many scholars to re-think and question whether the current merger control framework is suitable for the ICT sector, which is often also referred to as the new economy. The book pursues an interdisciplinary approach combining insights from law, economics and corporate strategy. Further, it has a comparative dimension, as it discusses the practices of the US, the EU and, wherever relevant, of other competition authorities from around the globe. Considering that the research was conducted in the EU, the practices of the European Commission remain a key aspect of the content.Considering its normative dimension, the book concentrates on the substantive aspects of merger control. To facilitate a better understanding of the most important points, the book also offers a brief overview of the procedural aspects of merger control in the EU, the US and the UK, and discusses recent amendments to Austrian and German law regarding the notification threshold. Given its scope, the book offers an invaluable guide for competition law scholars, practitioners in the field, and competition authorities worldwide.

All are agreed that the digital economy contributes to a dynamic evolution of markets and competition. Nonetheless, concerns are increasingly raised about the market dominance of a few key players. Because these companies hold the power to drive rivals out of business, regulators have begun to seek scope for competition enforcement in cases where companies claim that withholding data is needed to satisfy customers and cut costs. This book is the first focus on how competition law enforcement tools can be applied to refusals of dominant firms to give access data on online platforms such as search engines, social networks, and e-commerce platforms – commonly referred to as the ‘gatekeepers’ of the Internet. The question arises whether the denial of a dominant firm to grant competitors access to its data could constitute a ‘refusal to deal’ and lead to competition law liability under the so-called ‘essential facilities doctrine', according to which firms need access to shared knowledge in order to be able to compete. A possible duty to share data with rivals also brings to the forefront the interaction of competition law with data protection legislation considering that the required information may include personal data of individuals. Building on the refusal to deal concept, and using a multidisciplinary approach, the analysis covers such issues and topics as the following: – data portability; – interoperability; – data as a competitive advantage or entry barrier in digital markets; – market definition and dominance with respect to data; – disruptive versus sustaining innovation; – role of intellectual property regimes; – economic trade-off in essential facilities cases; – relationship of competition enforcement with data protection law and – data-related competition concerns in merger cases. The author draws on a wealth of relevant material, including EU and US decision-making practice, case law, and policy documents, as well as economic and empirical literature on the link between competition and innovation. The book concludes with a proposed framework for the application of the essential facilities doctrine to potential forms of abuse of dominance relating to data. In addition, it makes suggestions as to how data protection interests can be integrated into competition policy. An invaluable contribution to ongoing academic and policy discussions about how data-related competition concerns should be addressed under competition law, the analysis clearly demonstrates how existing competition tools for market definition and assessment of dominance can be applied to online platforms. It will be of immeasurable value to the many jurists, business persons, and academics concerned with this very timely subject.

In her PhD thesis, Giulia Aurélie Sonderegger analyses killer acquisitions, which, in short, are acquisitions that aim to pre-empt potential future competition at an early stage. While this phenomenon was originally discovered in pharmaceutical markets, this thesis exclusively discusses killer acquisitions in the context of digital markets, thereby primarily focusing on the current European Merger Control Regulation (EUMR). The main research question is whether the EUMR is appropriate to tackle killer acquisitions occurring in digital markets, and if not, in what ways it needs to be amended to better address the challenges in the future. To tackle this question, the author assesses both the economic and legal effects of killer acquisitions on merger control in digital markets and, based on her findings, suggests amendments to the current European merger control regime. For a more comprehensive analysis, this thesis also includes an assessment of the recently enacted Digital Markets Act (DMA) to ascertain whether this regulation may serve as an additional tool to remedy such transactions.

The digital economy is gradually gaining traction through a variety of recent technological developments, including the introduction of the Internet of things, artificial intelligence and markets for data. This innovative book contains contributions from leading competition law scholars who map out and investigate the anti-competitive effects that are developing in the digital economy.
