The purpose of this collection of essays in law and economics is to shed new light on the subject matter that Erling Eide has taken an interest in during his academic career -- as a student, teacher and scholar. The volume includes articles that analyse the law from the economic point of view, as well as other contributions at the intersection of economics and law or of relevance to it. Among the contributors are: Bettina Banoun, Roger Bowles, Jon Elster and Kalle Määttä.
