Institution

Institutions (singular: institution) are humanly devised structures of rules and norms that shape and constrain individual behavior. All definitions of institutions generally entail that there is a level of persistence and continuity. Laws, rules, social conventions and norms are all examples of institutions. Institutions vary in their level of formality and informality. Institutions are a principal object of study in social sciences such as political science, anthropology, economics, and sociology (the latter described by Émile Durkheim as the "science of institutions, their genesis and their functioning"). Primary or meta-institutions are institutions such as the family or money that are broad enough to encompass sets of related institutions. Institutions are also a central concern for law, the formal mechanism for political rule-making and enforcement. Historians study and document the founding, growth, decay and development of institutions as part of political, economic and cultural history. There are a variety of definitions of institutions. These definitions entail varying levels of formality and organizational complexity. The most expansive definitions may include informal but regularized practices, such as handshakes, whereas the most narrow definitions may only include institutions that are highly formalized (e.g. have specified laws, rules and complex organizational structures). According to Wolfgang Streeck and Kathleen Thelen, institutions are in the most general sense "building blocks of social order: they represent socially sanctioned, that is, collectively enforced expectations with respect to the behavior of specific categories of actors or to the performance of certain activities. Typically, they involve mutually related rights and obligations for actors." Sociologists and anthropologists have expansive definitions of institutions that include informal institutions. Political scientists have sometimes defined institutions in more formal ways where third parties must reliably and predictably enforce the rules governing the transactions of first and second parties.
