An important work and worth the time.
Format: Hardcover
Real scholarship addressing difficult but important topics in history, economic history, and development. What every economist should read to think much more deeply about how institutions, culture, and human agency interact. At the same time, scholars like the three co-authors demonstrate that there still remains the possibility of doing work that isn’t larded with ideological or activist posturing. Highly recommended.
