Continuing his groundbreaking analysis of economic structures, Douglass North here develops an analytical framework for explaining the ways in which institutions and institutional change affect the performance of economies, both at a given time and over time. Institutions exist, he argues, due to the uncertainties involved in human interaction; they are the constraints devised to structure that interaction. Yet institutions vary widely in their consequences for economic performance; some economies develop institutions that produce growth and development, while other economies develop institutions that produce stagnation.
