The factors we have listed (innovation, economies of scale, education, capital accumulation, etc.) are not causes of growth; they are growth. - Douglass North

Institutions are the humanly devised constraints that structure political, economic, and social interactions. They consist of both informal constraints (sanctions, taboos, customs, tradition, and code of conduct) and formal rules (constitutions, laws, property rights).

Order in the societies they describe is the result of a dense social network where people have an intimate understanding of each other and the threat of violence is a continuous force for preserving order because of its implications for other members of society.

A final aspect of all open access orders is Schumpeter’s notion of creative destruction, one of the most powerful descriptions of a competitive, open access economy. When Schumpeter wrote Capitalism, Socialism, and Democracy in the early 1940s, the economic theory of perfect competition among atomistic firms (i.e., firms too small to have market power) had come under sustained attack as unrealistic. Large and powerful economic organizations dominated the new economy, and their behavior did not match the textbooks. Despite this dominance, the economy produced historically unprecedented, sustained economic development. Schumpeter asked, How could large businesses that were supposed to choke off competition and growth nonetheless generate such spectacular productivity increases in a world that seemed ever more competitive?
