Comparative law and economics is an interdisciplinary research field in which differences among legal systems are analyzed from an economic point of view. The papers in this path-breaking collection illustrate those differences, describe their economic effects and discover which legal rules or systems are optimal from an economic viewpoint. The volume brings together twenty important contributions on property law, contract law, tort law, corporate law, intellectual property law, litigation law and the legal system, and shows how economics can enrich the study of comparative law.
