Work

Wernerfelt has done foundational and often iconoclastic work in economics, management strategy, and marketing. He is best known for “A Resource-based View of the Firm”, which is one of the most cited papers in the social sciences. Based on the premise that firms are heterogeneous, the article characterizes sustainable differences, suggests that optimal competitive strategies are based on leveraging excess capacity of these resources, and describes how current resources can be used to develop new ones.
In the last several years, Wernerfelt has been working on an economic theory of the firm. A fairly comprehensive statement of the theory can be found in “The Comparative Advantages of Firms, Markets, and Contracts: A Unified Theory”.
The paper portrays the most efficient labor market mechanism as a function of the advantages of specialization, workers’ costs of switching between entrepreneurs, and the frequency with which entrepreneurs’ needs change. Under the assumptions of the model, there exist three regions in which firms, markets, and sequences of bilateral contracts are weakly more efficient than all other mechanisms in a big class. Echoing the management literature, the firm grows as long as it can use specialized employees to perform the new tasks. The scope of the firm is determined by the point at which this no longer is possible.
As part of this stream, Wernerfelt has written several papers on the nature and incidence of bargaining costs. In other works, he has developed implications of the theory to show that the employer should own most of the productive assets, that incentives are weaker inside firms, and that more information is communicated within than between firms.
In the book, “Adaptation, Specialization, and the Theory of the Firm: Foundations of the Resource-Based View”, Wernerfelt starts with his economic theory of the firm and derives the Resource-Based View, thus showing that the two perspectives are consistent.
