The key role of "incentives" in family law is considered in this economic approach to family law. The book discusses the possible adverse consequences emanating from faulty legal design, while demonstrating that good family law should provide incentives for consistent and honest behavior. Economists, specialists in the economic analysis of law, and academic lawyers discuss recent advances in specialized studies of marriage, cohabitation, and divorce. This important new work will be of considerable interest to lawyers, policy-makers and economists concerned with family law.
