Judges play a central role in the American legal system, but their behavior as decision-makers is not well understood, even among themselves. The system permits judges to be quite secretive (and most of them are), so indirect methods are required to make sense of their behavior. Here, a political scientist, an economist, and a judge work together to construct a unified theory of judicial decision-making. Using statistical methods to test hypotheses, they dispel the mystery of how judicial decisions in district courts, circuit courts, and the Supreme Court are made.

The authors derive their hypotheses from a labor-market model, which allows them to consider judges as they would any other economic actors: as self-interested individuals motivated by both the pecuniary and non-pecuniary aspects of their work. In the authors' view, this model describes judicial behavior better than either the traditional “legalist” theory, which sees judges as automatons who mechanically apply the law to the facts, or the current dominant theory in political science, which exaggerates the ideological component in judicial behavior. Ideology does figure into decision-making at all levels of the federal judiciary, the authors find, but its influence is not uniform. It diminishes as one moves down the judicial hierarchy from the Supreme Court to the courts of appeals to the district courts. As The Behavior of Federal Judges demonstrates, the good news is that ideology does not extinguish the influence of other components in judicial decision-making. Federal judges are not just robots or politicians in robes.

This book takes a fresh look at the most dynamic area of American law today, comprising the fields of copyright, patent, trademark, trade secrecy, publicity rights, and misappropriation. Topics range from copyright in private letters to defensive patenting of business methods, from moral rights in the visual arts to the banking of trademarks, from the impact of the court of patent appeals to the management of Mickey Mouse. The history and political science of intellectual property law, the challenge of digitization, the many statutes and judge-made doctrines, and the interplay with antitrust principles are all examined. The treatment is both positive (oriented toward understanding the law as it is) and normative (oriented to the reform of the law).

Previous analyses have tended to overlook the paradox that expanding intellectual property rights can effectively reduce the amount of new intellectual property by raising the creators' input costs. Those analyses have also failed to integrate the fields of intellectual property law. They have failed as well to integrate intellectual property law with the law of physical property, overlooking the many economic and legal-doctrinal parallels.

This book demonstrates the fundamental economic rationality of intellectual property law, but is sympathetic to critics who believe that in recent decades Congress and the courts have gone too far in the creation and protection of intellectual property rights.

Written by a lawyer and an economist, this is the first full-length economic study of tort law--the body of law that governs liability for accidents and for intentional wrongs such as battery and defamation. Landes and Posner propose that tort law is best understood as a system for achieving an efficient allocation of resources to safety--that, on the whole, rules and doctrines of tort law encourage the optimal investment in safety by potential injurers and potential victims.

The book contains both a comprehensive description of the major doctrines of tort law and a series of formal economic models used to explore the economic properties of these doctrines. All the formal models are translated into simple commonsense terms so that the "math less" reader can follow the text without difficulty; legal jargon is also avoided, for the sake of economists and other readers not trained in the law.

Although the primary focus is on explaining existing doctrines rather than on exploring their implementation by juries, insurance adjusters, and other "real world" actors, the book has obvious pertinence to the ongoing controversies over damage awards, insurance rates and availability, and reform of tort law-in fact it is an essential prerequisite to sound reform. Among other timely topics, the authors discuss punitive damage awards in products liability cases, the evolution of products liability law, and the problem of liability for "mass disaster" torts, such as might be produced by a nuclear accident. More generally, this book is an important contribution to the "law and economics" movement, the most exciting and controversial development in modern legal education and scholarship, and will become an obligatory reference for all who are concerned with the study of tort law.
