Law and economics has arguably become one of the most influential theories in contemporary legal theory and adjudication. The essays in this volume, authored by both legal scholars and economists, constitute lively and critical engagements between law and economics and new institutional economics from the perspectives of legal and evolutionary theory. The result is a fresh look at core concepts in law and economics – such as ‘institutions’, ‘institutional change’ and ‘market failure’ – that offer new perspectives on the relationship between economic and legal governance. The increasingly transnational dimension of regulatory governance presents lawyers, economists and social scientists with an unprecedented number of complex analytical and conceptual questions. The contributions to this volume engage with legal theory, new institutional economics, economic sociology and evolutionary economics in an interdisciplinary assessment of the capacities and limits of the state, markets and institutions. Drawing as well upon legal sociology and the philosophy of law, the authors expand and transform the known terrain of ‘law and economics’ by applying evolutionary theory to both law and economics from a domestic and transnational perspective. Legal scholars, evolutionary and regulatory theorists, economists, economic sociologists, economic historians and political scientists will find this cutting-edge volume both challenging and engaging.Contributors: M.
