The boundaries of the firm have been a major issue in economics, strategic management, and international business during the eight decades since the publication of Ronald Coase’s (1937) groundbreaking work “The Nature of the Firm.” In the field of Economics, Coase’s work helped to give new life to the theory of the firm and created new approaches to industrial organization (cf. Alchian and Demsetz, 1972; Klein et al., 1978), and in strategic management it helped to make the analysis of vertical integration and the scope of the firm central research concerns (Hennart, 1982; Williamson, 1973).
