"David Friedman, a first-rate economist with a good deal of experience in applying economics to the law, has written a lucid, imaginative, entertaining, opinionated, and, on balance, a very fine introduction to the application of economics to law. The book is wide-ranging in scope, at once simple and highly sophisticated, consistently provocative, an excellent read, and a notable contribution to an exciting field of interdisciplinary studies."--Richard A. Posner, Chief Judge, United States Court of Appeals For the Seventh Circuit "David Friedman explains in clear and accessible language what basic economic theory adds to the understanding of law, and how simple concepts of rationality, value, and transaction costs can go a long way to bring out the hidden unity among various diverse branches of law. Whether one speaks of the complexities of marginal deterrence, the resolution of disputes between farmers and railroads, or the social functions of copyright and patent law, Friedman's book provides the outsider to the field with a comprehensive but accessible account of his legal subject matter."--Richard A. Epstein, University of Chicago
