Leading scholars, including Kenneth Arrow, Kenneth Elzinga, Victor Goldberg, Jack Hirschliefer, Paul Joskow, and Vernon Smith, have chosen Research in Law and Economics as the right forum for presenting their research.Now published bi-annually by Elsevier, each issue of Research in Law and Economics focuses on a timely and relevant topic. Such topics have included economics of environmental policy, urban property rights, antitrust and evolutionary models in economics and law. This volume focuses on cost-benefit analysis and the law.Research in Law and Economics is now available online at ScienceDirect - full-text online from volume 19 onwards.
