Nobel laureate economist Douglass North argued early on that human society created institutions to deal with information asymmetry, but that their creations immediately gave rise to the problem of how to constrain such institutions to fulfill their intended objectives. In 2000, Oliver E. Williamson classified four levels of social analysis for institutions – informal institutions, customs, traditions, norms, and religion; formal institutions with rules governing property rights, social order, the judiciary, and the bureaucracy; governance structures and their alignment to economize on transaction costs; and decentralized decision-making in resource allocation (the domain of neo-classical economics).
