Law and economics

ja:法と経済学

Law and economics is the term usually applied to an approach to legal theory that incorporates methods and ideas borrowed from the discipline of economics. It's existence as a discipline can be almost exclusively attributed to funding from the John M. Olin Foundation.

Relationship to Other Disciplines and Approaches

As used by lawyers and legal scholars, the phrase "law and economics" refers to the application of the methods of economics to legal problems. Because of the overlap between legal systems and political systems, some of the issues in law and economics are also raised in political economy and political science. Most formal academic work done in law and economics is broadly within the Neoclassical tradition. Approaches to the same issues from Marxist and critical theory/Frankfurt School perspectives usually do not identify themselves as "law and economics." For example, research by members of the critical legal studies movement considers many of the same fundamental issues as does work labeled "law and economics". The one wing that represents a non-neoclassical approach to "law and economics" is the Continental (mainly German) tradition that sees the concept starting out of the Staatswissenschaften approach and the German Historical School of Economics; this view is represented in the Elgar Companion to Law and Economics (2nd ed. 2005) and - though not exclusively - in the European Journal of Law and Economics. Here, consciously non-neoclassical approaches to economics are used for the analysis of legal (and administrative/governance) problems.

Positive and Normative Law and Economics

Economic analysis of law is usually divided into two subfields, positive and normative.

Positive Law and Economics

Positive law and economics uses economic analysis to predict the effects of various legal rules. So, for example, a positive economic analysis of tort law would predict the effects of a strict liability rule as opposed to the effects of a negligence rule.

Normative Law and Economics

Normative law and economics goes one step further and makes policy recommendations based on the economic consequences of various policies. The key concept for normative economic analysis is efficiency. The weakest concept of efficiency used by law and economics scholars is Pareto efficiency. A legal rule is Pareto efficient if it makes at least one person better off and it makes no person worse off. (By weak, economists mean that Pareto efficiency makes very few normative assumptions, not that it is supported by weak arguments.) A stronger conception of efficiency is Kaldor-Hicks efficiency. A legal rule is Kaldor-Hicks efficient if it could be made Pareto efficient by a side payment.

Influence of the Law and Economics Movement

In the United States, economic analysis of law has been extremely influential. Among the key figures in the law and economics movement are the Nobel Prize winning economist Ronald Coase and Richard Posner, formerly a colleague of Coase at the University of Chicago and currently a judge on the United States Court of Appeals for the Seventh Circuit. This influence has, in turn influenced legal education. Another prominent legal scholar from the Law and Economics movement is Robert Bork, a former Supreme Court nominee. Many law schools in the North America, Europe, and Asia have faculty members with a graduate degree in economics. In additon, many professional economists now study and write on the relationship between economics and legal doctrine.

Criticisms of Law and Economics

Despite its influence, the law and economics movement has been criticized from a number of directions. This is especially true of normative law and economics. Because most law and economics scholarship operates within a neoclassical framework, fundamental criticisms of neoclassical economics have been applied to work in law and economics. Within the legal academy, law and economics has been criticized on the ground that rational choice theory makes unrealistic simplifying assumptions about human nature; Posner's infamous application of law and economic reasoning to rape and sex [1] (http://www.amazon.com/exec/obidos/tg/detail/-/0674802802/104-2295424-2145552?v=glance) may be an example of this. Liberal critics of the law and economics movements have argued that normative economic analysis does not capture the importance of human rights and concerns for distributive justice.

Contemporary Developments

Law and economics has developed in a variety of directions. One important trend has been the application of game theory to legal problems. Other developments have been the incorporation of behavioral economics into economic analysis of law, and the increasing use of statistical and econometrics techniques. Within the legal academy, the term socio-economics has been applied to economic approaches that are self-consciously broader than the neoclassical tradition.


Universities with Law and Economics Programs

The John M. Olin Foundation has provided grants worth millions of dollars to fund Law and economics programs at the following schools(partial list).

Interestingly, in 1985 the University of California in Los Angeles rejected the Olin Program in Law and Economics after only 1 year. Students were given John M. Olin fellowships, taught almost exclusively by John M. Olin faculty and required to attend events with right-wing speakers such as Robert Bork and Antonin Scalia. The UCLA Law School Curriculum Committee decided to turn down the the Olin Foundation's substantial funding offer because it was "taking advantage of students' financial need to indoctrinate them with a particular ideology."
