F. H. Buckley''s new book fills a prominent hole in the literature, explaining economic terms and jargon with welcome clarity and examining the moral basis of free contracting, as well as those cases where bargaining rights might reasonably be restricted. Along the way the book examines several philosophical puzzles, such as allegiance requirements, paternalism and fairness constraints. Buckley approaches fundamental issues of contract law from an economic perspective, though the book is far from being overly technical and will appeal equally to economists, philosophers and law students. This is a welcome addition to the literature on law and economics.
