Pioneer, avant-garde, transformationalist - Eleanor M. Fox is regularly described in these terms by the manifold antitrust practitioners who have been influenced by her industry-shaping scholarly work. Over the course of an extraordinary career, she has helped establish a coherent set of competition law and policy principles designed to promote markets that work in favor of inclusivity, and to ensure economic development that reduces unequal access to markets. Her mold-breaking contributions to the tailored development of competition law in developing economies are acknowledged today across international forums that she helped create. This book honours Professor Fox's indelible mark on antitrust law and policy with contributions from her friends and colleagues around the world. The articles explore subjects such as the role of competition policy, its intersection with social policies, external pressures, and challenges for developing economies amongst others.
