This Research Handbook offers a thorough analysis of the complex relationship between digital technologies, competition and market dynamics, from a multidisciplinary perspective. Leading specialists in the field explore the evolution of competition enforcement in response to technological change and examine its intersections with other policy areas, such as data protection, intellectual property and labour law. A distinctive feature of the Handbook is its in-depth analysis of how competition policy tools have adapted to address the challenges posed by the unique attributes of digital technologies. This focus positions the Handbook as an invaluable resource for understanding the profound changes artificial intelligence will introduce to the competition policy landscape. Individual chapters discuss the different contexts in which competition and technology intersect, including; antitrust damages, e-commerce, information exchange, technological change and vertical agreements in relation to data and market power. The contributing authors also shed light on the impact of geopolitics on mergers and acquisitions, as well as the role of the gig economy in studies of labour law. Additional insights include case studies on antitrust policies on social media and an analysis of the landmark European Media Freedom Act legislation.
