The intermediation theory of the firm: integrating economic and management approaches to strategy

Economic and management perspectives on management strategy can and should be integrated. The intermediation theory of the firm and models of market microstructure provide a basis for advancing the integration of management and economics perspectives. In particular, the theory allows for a combination of economic approaches such as Porter's work on competitive strategy with management approaches such as work on the abilities and resources of the organization. The article presents a unified strategy framework based on transaction costs and the intermediation theory of the firm. Copyright © 2003 John Wiley & Sons, Ltd.
