Douglass North quotes
Institutions are the humanly devised constraints that structure political, economic, and social interaction. They consist of both informal constraints (sanctions, taboos, customs, traditions, and codes of conduct), and formal rules (constitutions, laws, property rights). Throughout history, institutions have been devised by human beings to create order and reduce uncertainty in exchange.
Douglass North
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?
