The fifth edition of this classic reader retains many of the articles that have made the book a must-assign for classes on development and political economy, but has been updated with 14 new chapters that look even more deeply at long-term factors that help to explain the origins and current trends in the gap between rich and poor. An entirely new section focuses on natural resource and environmental issues, and the appendix of wealth and inequality indicators has been fully revised. The editors? short introduction to each selection, highlighting its significance, remains a key feature of the book.
