In an era where technology is evolving at breakneck speed and populist movements are reshaping political landscapes, the regulation of market participants stands at a critical crossroads. The future of antitrust -- once a relatively stable domain of law and policy -- is now caught in a fierce battle between traditional doctrines and emerging approaches that seek to address the new realities of our time. This book delves into this struggle, offering a thought-provoking exploration of how antitrust laws have evolved, how they are being challenged, and what is at stake for the future. Through a unique lens that juxtaposes the legacies of Louis Brandeis, Robert Bork, and Joseph Schumpeter, this book offers an insightful analysis of the forces shaping the future of antitrust. By tracing the historical evolution of antitrust law through economic theory and examining the ongoing debates that define today's regulatory environment, the author provides a comprehensive yet accessible guide to the competing schools of thought in this critical field. This is a highly valuable resource for a diverse readership interested in the future of competition law and the broader regulation of innovation, from legal experts to students of law and economics, as well as professionals and policymakers navigating the complexities of market regulation.
