Many ecomic problems are also ethical problems: should we value ecomic equality? how much should we care about preserving the environment? how should medical resources be divided between saving life and enhancing life? This book examines some of the practical issues that lie between ecomics and ethics, and shows how utility theory can contribute to ethics. John Broome's work has, unusually, combined sophisticated ecomic and philosophical expertise, and Ethics Out of Ecomics brings together some of his most important essays, augmented with an updated introduction. The first group of essays deals with the relation between preference and value, the second with various questions about the formal structure of good, and the concluding section with the value of life. This work is of interest and importance for both ecomists and philosophers, and shows powerfully how ecomic methods can contribute to moral philosophy.
