Daron Acemoglu and James Robinson argue that the difference between rich and poor nations lies not in geography, culture, or the luck of natural resources, but in their institutions. Inclusive political and economic institutions—those that distribute power broadly and allow people to participate in economic life—enable prosperity. Extractive institutions—those that concentrate power and extract wealth from the many for the benefit of the few—produce poverty and stagnation. The authors draw on examples spanning millennia: why Rome flourished and fell, why China's early innovations didn't produce industrialization, why North and South Korea diverged, why Botswana succeeded where other African nations failed. Acemoglu, an economist at MIT, and Robinson, a political scientist at the University of Chicago, combine rigorous scholarship with accessible writing. They engage critics who emphasize culture or geography, showing how institutional explanations better account for the evidence. The book has become required reading in development economics and political science, influential in policy circles worldwide. It offers both a theory of history and a practical agenda: prosperity follows when institutions become more inclusive.
