Most institutional theories see local actors – whether individuals, organizations, or national states – as affected by institutions built up in much … - John W. Meyer

Contemporary institutional theorizing in the field of organizations dates back thirty-odd years. This particularly describes what are called new or neo-institutionalisms. These terms evoke contrasts with earlier theories of the embeddedness of organizations in social and cultural contexts, now retrospectively called the ‘old institutionalism’ (Hirsch & Lounsbury, 1997; Stinchcombe, 1997). They went through a period of inattention, so that when institutional thinking came back in force after the 1960s, it seemed quite new.
Institutional theories, as they emerged in the 1970s, received much attention in the field, along with other lines of thought emphasizing the dependence of modern organizations on their environments. Perhaps surprisingly, they continue to receive attention, and seem to retain substantial measures of vigor.

Many formal organizational structures arise as reflections of rationalized institutional rules. The elaboration of such rules in modern states and societies accounts in part for the expansion and increased complexity of formal organizational structures. Institutional rules function as myths which organizations incorporate, gaining legitimacy, resources, stability, and enhanced survival prospects. Organizations whose structures become isomorphic with the myths of the institutional environment-in contrast with those primarily structured by the demands of technical production and exchange-decrease internal coordination and control in order to maintain legitimacy. Structures are decoupled from each other and from ongoing activities. In place of coordination, inspection, and evaluation, a logic of confidence and good faith is employed.

Some institutionalist lines of thought, arising particularly in economics and political science, retain very strong notions of society as made up of bounded, purposive, sovereign, and rational actors. In economics, these might be individuals or organizations, operating in market-like environments. In political science, they might be sovereign national-states operating in an almost anarchic environment. Institutionalism, in such schemes, involves the idea that some fundamental institutional principle must be in place before systems of such actors can effectively operate. The classic core principle required in economic versions is property rights (North & Thomas, 1973). In international relations theory it is the principle of nation-state sovereignty (Krasner, 1999).
