This paper examines the historical developments of the institutionalist theory of the business enterprise since early 1900s. We will examine the major contributions in order to find the theoretical characteristics of the institutionalist theory of the business enterprise vis-à-vis evolving capitalism. The paper begins with a discussion of the present state of the institutional theory, looks back on the original ideas of Veblen and Commons, and goes on to later contributions, such as Gardiner Means, John Kenneth Galbraith, William Dugger, and Alfred Eichner. The paper concludes with a discussion as to what should be done for the further development of the institutionalist theory of the business enterprise.
