What is the role of law in a society in which order is maintained mostly through social norms, trust, and nonlegal sanctions? Eric Posner argues that social norms are sometimes desirable yet sometimes odious, and that the law is critical to enhancing good social norms and undermining bad ones. But he also argues that the proper regulation of social norms is a delicate and complex task, and that current understanding of social norms is inadequate for guiding judges and lawmakers. What is needed, and what this book offers, is a model of the relationship between law and social norms. The model shows that people's concern with establishing cooperative relationships leads them to engage in certain kinds of imitative behavior. The resulting behavioral patterns are called social norms. Posner applies the model to several areas of law that involve the regulation of social norms, including laws governing gift-giving and nonprofit organizations; family law; criminal law; laws governing speech, voting, and discrimination; and contract law. Among the engaging questions posed are: Would the legalization of gay marriage harm traditional married couples? Is it beneficial to shame criminals? Why should the law reward those who make charitable contributions? Would people vote more if non-voters were penalized? The author approaches these questions using the tools of game theory, but his arguments are simply stated and make no technical demands on the reader.

This book proposes the study of norms as a method of explaining human choice and behaviour by introducing a new scientific perspective. The science of norms may here be broadly understood as a social science which includes elements from both the behavioural and legal sciences. It is given that a science of norms is not normative in the sense of prescribing what is right or wrong in various situations. Compared with legal science, sociology of law has an interest in the operational side of legal rules and regulation. This book develops a synthesizing social science approach to better understand societal development in the wake of the increasingly significant digital technology. The underlying idea is that norms as expectations today are not primarily related to social expectations emanating from human interactions but come from systems that mankind has created for fulfilling its needs. Today the economy, via the market, and technology via digitization, generate stronger and more frequent expectations than the social system. By expanding the sociological understanding of norms, the book makes comparisons between different parts of society possible and creates a more holistic understanding of contemporary society. The book will be of interest to academics and researchers in the areas of sociology of law, legal theory, philosophy of law, sociology and social psychology.

This book contains perspectives of world-renowned scholars from the fields of law, economics, and political science about the relationship between law and norms. The authors take different approaches by using a wide variety of perspectives from law, legal history, neoclassical economics, new institutional economics, game theory, political science, cognitive science, and philosophy. The essays examine the relationship between norms and the law in four different contexts. Part One consists of essays that use the perspectives of cognitive science and behavioral economics to analyze norms that influence the law. In Part Two, the authors use three different types of common property to examine cooperative norms. Part Three contains essays that deal with the constraints imposed by norms on the judiciary. Finally, Part Four examines the influence formal law has on norms.

One of the most prominent and urgent problems in international governance is how the different branches and norms of international law interact and what to do in the event of conflict. With no single 'international legislator' and a multitude of states, international organisations and tribunals making and enforcing the law, the international legal system is decentralised. This leads to a wide variety of international norms, ranging from customary international law and general principles of law, to multilateral and bilateral treaties on trade, the environment, human rights, the law of the sea, etc. Pauwelyn provides a framework on how these different norms interact, focusing on the relationship between the law of the World Trade Organisation (WTO) and other rules of international law. He also examines the hierarchy of norms within the WTO treaty. His recurring theme is how to marry trade and non-trade rules, or economic and non-economic objectives at the international level.

This collection contributes to the wider theoretical debate concerning the movement of law and legal norms by engaging with concrete examples of legal diffusion in jurisdictions as diverse as Albania, the Czech Republic, Poland and Kuwait. The volume is international, multi-disciplinary and multi-methodological in approach and brings together scholars from law and social science with experience in mixed and hybrid jurisdictions. The book provides timely new insights and a comprehensive illustration of the theoretical debates concerning the diffusion of laws and norms in terms of both process and form.

This book assesses the impact of norms on decision-making. It argues that norms influence choices not by being causes for actions, but by providing reasons. Consequently it approaches the problem via an investigation of the reasoning process in which norms play a decisive role. Kratochwil argues that, depending upon the strictness the guidance norms provide in arriving at a decision, different styles of reasoning with norms can be distinguished. While the focus in this book is largely analytical, the argument is developed through the interpretation of the classic thinkers in international law (Grotius, Vattel, Pufendorf, Rousseau, Hume, Habermas).

Frank Lovett presents a powerful theory of the rule of law and its connection to freedom and social justice.

Reprint of the first American edition. One of the most interesting jurists of the post-World War II era, Ross [1899-1979] was a legal and moral philosopher, scholar of international law and the leading representative of Scandinavian Legal Realism. This book and On Law and Justice (1958) are his principal works. In Directives and Norms Ross asks whether imperatives (or, to use his term, 'directives') are subject to logic in the same way as indicatives. He shows the difference between indicative and directive discourse and explains the concepts 'directive' and 'norm' as they function in the social sciences, especially in the study of law. A contemporary essay in the Modern Law Review (32:544), though critical of this work, was still impressed by its "clear and convincing account" of these processes.

Reprint of the second revised and enlarged edition, a complete revision of the first edition published in 1934. A landmark in the development of modern jurisprudence, the pure theory of law defines law as a system of coercive norms created by the state that rests on the validity of a generally accepted Grundnorm, or basic norm, such as the supremacy of the Constitution. Entirely self-supporting, it rejects any concept derived from metaphysics, politics, ethics, sociology, or the natural sciences. Beginning with the medieval reception of Roman law, traditional jurisprudence has maintained a dual system of "subjective" law (the rights of a person) and "objective" law (the system of norms). Throughout history this dualism has been a useful tool for putting the law in the service of politics, especially by rulers or dominant political parties. The pure theory of law destroys this dualism by replacing it with a unitary system of objective positive law that is insulated from political manipulation. Possibly the most influential jurisprudent of the twentieth century, Hans Kelsen [1881-1973] was legal adviser to Austria's last emperor and its first republican government, the founder and permanent advisor of the Supreme Constitutional Court of Austria, and the author of Austria's Constitution, which was enacted in 1920, abolished during the Anschluss, and restored in 1945. The author of more than forty books on law and legal philosophy, he is best known for this work and General Theory of Law and State. Also active as a teacher in Europe and the United States, he was Dean of the Law Faculty of the University of Vienna and taught at the universities of Cologne and Prague, the Institute of International Studies in Geneva, Harvard, Wellesley, the University of California at Berkeley, and the Naval War College. Also available in cloth.
