The digital economy is reinvigorating regulatory competition, yet little is known about which rules and jurisdictions can effectively bind companies nor what competitive motivations underlie certain rules. In addition to purely economic motives, legislators are now also driving the pursuit of digital sovereignty and the enforcement of social values in digital spaces. It also remains unclear what regulatory weight the self-regulation of private companies has in multi-level governance systems. This book examines regulatory competition in the three main pillars of digital markets: artificial intelligence, data, and platforms. It brings together legal scholars, economists and information systems experts, providing relevant examples and structured analysis of the aims and outcomes of regulatory competition in the digital economy.

“A timely exploration of the balancing acts regulators must perform to manage private power in a globalized digital economy. Essential for understanding the intersection of law, economics, and technology in the contemporary digital ecosystem.”

Jens Frankenreiter, Associate Professor of Law, Washington University

“Artificial Intelligence is fundamentally disrupting how we enable economic growth and how we regulate fair competition. Luckily, Denga and Hornuf provide a detailed and comprehensive overview of the thorniest and most complex regulatory issues while at the same time offering thoughtful and feasible solutions.  "Regulatory Competition in the Digital Economy" is a treasure trove for anyone interested in market regulation, fair competition, consumer protection, and geopolitical questions.”
