New institutionalism

Neo institutionalism (also referred to as neo-institutionalist theory or institutionalism) is an approach to the study of institutions that focuses on the constraining and enabling effects of formal and informal rules on the behavior of individuals and groups. New institutionalism traditionally encompasses three major strands: sociological institutionalism, rational choice institutionalism, and historical institutionalism. New institutionalism originated in work by sociologist John Meyer published in 1977.
