This book is the first to apply the tools of game theory and information economics to advance our understanding of how laws work. Organized around the major solution concepts of game theory, it shows how such well known games as the prisoner's dilemma, the battle of the sexes, beer-quiche, and the Rubinstein bargaining game can illuminate many different kinds of legal problems. Game Theory and the Law highlights the basic mechanisms at work and lays out a natural progression in the sophistication of the game concepts and legal problems considered.

This book considers three relationships: law and economics; economics and game theory; and game theory and law. Economists teach lawyers that economic principles cut across and integrate seemingly different legal subjects such as contracts, torts, and property. Correspondingly, lawyers teach economists that legal rationality is a separate and distinct decision-making process that can be formalized by behavioral rules that are parallel to and comparable with the behavioral rules of economic rationality, that efficiency often must be constrained by legal goals such as equal protection of the laws, due process, and horizontal and distributional equity, and that the general case methodology of economics vs. the hard case methodology of law for determining the truth or falsity of economic theories and theorems sometimes conflict. Economics and Game Theory: Law and economics books focus on economic analysis of judges’ decisions in common law cases and have been mostly limited to contracts, torts, property, criminal law, and suit and settlement. There is usually no discussion of the many areas of law that require cooperative action such as is needed to provide economic infrastructure, control public “bad” type externalities, and make legislation. Game theory provides the bridge between competitive markets and the missing discussion of cooperative action in law and economics. How? Competitive markets are examples (subset) of the Prisoners’ Dilemma, which explains the conflict between individual self-interested behavior and cooperation both in economic markets and in legislative bodies and demonstrates the need for social infrastructure and regulation of pollution and global warming. Game Theory and Law: Lawsuits usually involve litigation between two parties, not the myriad participants in markets, so the assumption of self-interest constrained by markets does not carry over to legal disputes involving one-on-one bargaining in which the law gives one party superior bargaining power. Game theory models predict the effect of different legal institutions, rights, and rules on the outcome of such bargaining. Game theory also has a natural four-model framework which is used in this book to analyze the law and economics of civil obligation, which consists of torts (negligence), contracts, and unjust enrichment.

Using game theory and examples of actual games people play, Nobel laureate Manfred Eigen and Ruthild Winkler show how the elements of chance and rules underlie all that happens in the universe, from genetic behavior through economic growth to the composition of music. To illustrate their argument, the authors turn to classic games--backgammon, bridge, and chess--and relate them to physical, biological, and social applications of probability theory and number theory. Further, they have invented, and present here, more than a dozen playable games derived from scientific models for equilibrium, selection, growth, and even the composition of RNA.

Game theory is a branch of mathematics that studies strategic interactions, i.e., interactions which involve more than one agent and in which each agent makes her/his decision while striving to predict the decisions of other agents. Game theory has been successfully applied in many areas of both the natural and social sciences, and it is the belief of this book's author that it can also be gainfully invoked in the area of legal philosophy. In this book, Wojciech Zaluski analyzes legal-philosophical concepts - such as legal interpretation, justice, legal rights, contract law, tort law, and property law - through the lens of game theory. The book appeals mainly to game theory's conceptual rather than the technical side, and intertwines game-theoretical analysis with the philosophical. It will be accessible to a wider circle of readers interested in legal and moral philosophy.
