This paper argues that the resource-based approach of deductive economics, the dynamic capabilities approach of strategy process, and organization theory research on organizational learning need to be joined in the next generation of resource-based research. This suggested redirection of resourcebased research implies a return to a "resource-learning" theory of the firm begun by Penrose (1959).A synthesis of resource-based theory and learning theory allows us to examine how two sources of firm heterogeneity (resources and mental models) are intertwined.
THE MANAGEMENT OF RESOURCES AND THE RESOURCE OF MANAGEMENTA consensus is beginning to emerge in strategic management that calls for an active attempt to increase the dialogue between behavioral and economic approaches to strategy issues (Amit and Schoemaker, 1993;Barney, 1992;Eisenhardt, 1989;Mahoney, 1992b;Schoemaker, 1993;Zajac, 1992). In the spirit of this pluralistic and balanced approach (Bowman, 1990;Rumelt, Schendel and Teece, 1991), it is suggested that the literature on organizational learning (behavioral literature) can and should be united with the emerging resource-based view of the firm (a more economic approach).Specifically, this paper argues that a holistic approach which combines behavioral logic with economic logic is necessary for advancing the theory of invisible assets (Itami and Roehl, 1987) and sustainable competitive advantage. Williamson (1991) notes the uncertainty of whether the dynamic capabilities approach (Nelson and Winter, 1982;Prahalad and Hamel, 1990;Rumelt, 1984; Teece, 1990) --in which organizational learning should certainly be a part --and the resource-based approach (Barney, 1991;Conner, 1991;Peteraf, 1993;Wernerfelt, 1984) will play out individually or in combination. The argument here is that communication can and should flow freely between participants of the two approaches. In fact, the two approaches naturally blend into each other (Mahoney and Pandian, 1992 (Collis, 1991;Tallman, 1991). In the resource-based view, the concept of strategy is considered as a "continuing search for rent" (Bowman, 1974, p. 47) (Penrose, 1959).In contrast to (strong form) efficient market theorists, most resource-based theorists insist that short-term economic rents are possible (Schoemaker, 1990 (Conner, 1991). Third, entrepreneurial (Schumpeterian) rent may be achieved by risk-taking and entrepreneurial insight in an uncertain/complex environment (Rumelt, 1987;Schumpeter, 1934).Fourth, the firm may be able to appropriate rents when resources are firm-specific (Aharoni, 1993 (Andrews, 1980, pp. 63-71; Ansoff, 1965, pp. 90-102; Hofer and Schendel, 3 1978, pp. 144-153; Selznick, 1957, pp. 42-56 (Barney, 1991;Demsetz, 1973;Powell, 1992b productive services from existing resources present a "jig-saw puzzle" for balancing processes (Penrose, 1959, p. 70). Excess capacity due to indivisibilities, and cyclical demand, to a large extent drives the diversification process (Chandler, 1962;Farjoun, 1993 At all times there exists w...
