This book investigates the historical origins of the vast economic disparity between wealthy and impoverished nations. Robert C. Allen, a professor of economic history, utilizes a comparative framework to analyze how specific interactions between technological innovation, institutional development, and cultural factors have dictated the economic trajectories of different regions over the last several centuries. He argues that the divergence in global wealth is not an accident of geography but the result of specific policy choices and economic conditions.
