Institutional analysis is the part of the social sciences that studies how institutions—i.e., structures and mechanisms of social order and cooperation governing the behavior of two or more individuals—behave and function according to both empirical rules (informal rules-in-use and norms) and also theoretical rules (formal rules and law). This field deals with how individuals and groups construct institutions, how institutions function in practice, and the effects of institutions on each other, on individuals, societies and the community at large.[1]
