Leading experts unpack the core principles of data protection and investigate the technological and economic dynamics that shape its relationship with competition law. This Research Handbook examines the complex interplay between competition and data protection law, exploring such interplay across all key areas of competition law enforcement, such as agreements between firms, abuse of dominance, merger control, and the newly enacted Digital Markets Act. They analyse how competition law and policy can promote or hinder consumer privacy and data protection and present a detailed overview of various policy questions, comparing how jurisdictions worldwide address these issues. Presenting a detailed overview of various policy questions tackled from a multidisciplinary perspective (including computer science and data science), this Research Handbook is an important addition to the literature, highlighting the many nuances in this increasingly significant interface.
