This second edition of Law and Economics for Civil Law Systems substantially updates a unique work that presents the core ideas of law and economics for audiences primarily familiar with civil law systems.Ejan Mackaay offers a comprehensive look at the essential points of economic reasoning, the Coase Theorem, and legal institutions such as property, extra-contractual civil liability and contracts. The book’s structure mirrors the way law is taught in civil law countries, with structured presentations, references to civil code articles paired with non-technical explanations, and limited reliance on graphs. Building on the success of the 2008 edition of the French-language textbook on law and economics from a civil law perspective, this second English-language version appears alongside the 2021 edition of the French-language book.This pioneering volume fills a critical gap in the literature of law and economics and will be an invaluable resource for academia, the judiciary, policy-makers, regulators and legal practitioners working in civil law systems.
