This investigation will discuss the emergence of an economistical perspective among the dominant approaches of organization theory in the United States since the inception of "organization studies" as an academic discipline. It maintains that Contingency theory, Resource Dependency theory, Population Ecology theory, and Transaction Cost theory analyze predominantly for-profit organizations within the context of the current economic environment. It further holds that the political and cultural environments, as well as the role of communities, are widely neglected by the economistical perspective. The New Institutionalism departs from this line of thinking and offers an implicit critique. With this focus, this article addresses a sociology of knowledge theme and aims to account for this theoretical limitation by drawing on social developments in the American economy, in American politics, and in the academy. Finally, this study argues that the economization of organization studies is strongly supported by the increasing proliferation of American business schools. Here the science of organization studies has found its new institutional home.
