This is a new and significantly updated edition of a standard text for the field of Law and Economics. Taking a straightforward approach and written in an accessible manner without reliance on mathematical modelling, it is aimed at Law and Economics students in law schools as well as economics departments. New to this edition is new and substantially increased coverage of more contemporary fields of vision in the Law and Economics paradigm, such as Intellectual Property, Family Law, and Behavioural Economics. With an array of exercises and questions throughout the book, and extensive references to further reading, this text reflects the way Law and Economics is taught in a contemporary context.
