This volume collects the lectures of the 5th Law and Economics Conference at the Law Faculty of the University of Lucerne, all of them initiated and organized by Prof. Dr. Klaus Mathis, director of our Centre for Law and Sustainability. He has introduced and developed the subject of law and economics at the Law Faculty of the University of Lucerne with much endurance and passion. In recent years, Lucerne has become an important place for law and economics research in Europe, and we are proud of that. Furthermore, the new Faculty of Economics and Management will open its doors this summer, which will strengthen the economics side of this research. My special thanks are extended to Prof. Bruce Huber from the University of Notre Dame Law School, coeditor of this book and co-organizer of the 5th Law and Economics Conference. It is not by chance that Bruce Huber and Klaus Mathis have worked together in the organization of the conference and the editing of the book. The University of Notre Dame and the University of Lucerne are cooperating on other research projects and, moreover, have a student exchange agreement which allows our law students to gain experience at Notre Dame and vice versa.
