'Digital competition', a term and concept that has risen to the forefront of competition law, may be viewed as both promising and cautionary: on the one hand, it brings the promises of increased speed, efficiency and objectivity, and, on the other, it entails potential pitfalls such as hard-to-identify pathways to unfair pricing, dominant positions and their potential abuse, restriction of choice and abuse of personal data. Accordingly, jurisdictions around the world are taking measures to deal with the phenomenon. In this concise but thoroughly researched book - both informative and practical - lawyers from two prominent firms with specialised digital competition teams take stock and examine the state of digital competition in the enforcement practices of six competition authorities in Europe, most of these forerunners in the field of digital competition policy and enforcement.

The competition authorities surveyed are those of the European Union, the United Kingdom, France, Germany, the Netherlands and Belgium. For each, an overview, spanning the period from 2012 to mid-2022 but including as many landmark cases as possible up to and including December 2022, includes not only landmark cases in which digital technologies have had a significant impact on the competition law outcome but also guidance documents such as speeches, policy statements, industry surveys and research reports. Activities and enforcement practices of the various authorities include the following and more:

• degree of activity;

• focus of the activity;

• enforcement styles;

• enforcement instruments;

• visible effectiveness of enforcement; and

• important insights and outlooks.

Each overview contains separate chapters on cartel prohibition, the prohibition of abuse of a dominant position and merger control. Additional chapters - partially written by guest authors (who are all without a doubt true thought leaders: Tristan Byrne, Giuseppe Colangelo, Ai Deng, Teodora Groza, Daniel Mândrescu, Wolf Sauter, Thibault Schrépel, and Gareth Shier) - evaluate the similarities and differences in the enforcement practices and the positive and negative effects of digital competition in the jurisdictions investigated, the economic context, the most important game changers, and a concluding chapter offers recommendations.

An indispensable guide to quickly and accessibly acquiring in-depth knowledge of competition law in the digital sector, this matchless volume is a must-read for any practitioner or academic who encounters competition law related to digital markets. The dilemmas and challenges of the new competition law reality - which is here already, like it or not - are clearly explained here for the benefit of regulators, academics, policymakers, judges, in-house counsel and lawyers specialising in competition law and intellectual property law.
