Birger Wernerfelt

Birger Wernerfelt (born 1951) is a Danish economist and management theorist. He is the J. C. Penney Professor of Management Emeritus at the MIT Sloan School of Management at the Massachusetts Institute of Technology (MIT). He is known for his 1984 article, "A Resource-Based View of the Firm", which named and started the development of the resource-based view (RBV) in strategic management.

Early life and education Wernerfelt was born in Denmark. He studied at the University of Copenhagen, where he earned a BA in philosophy and an MA in economics. He subsequently attended Harvard University from 1974–76 and received a Doctor of Business Administration (DBA) in managerial economics.

Academic career Wernerfelt began his career as a research fellow in mathematical economics at the University of Copenhagen and then taught strategy at the University of Michigan and Northwestern before joining the MIT Sloan School of Management in 1989. He was a visiting professor of economics at the University of Copenhagen in the 2010–11 academic year.

He is married to Harvard Professor Cynthia Montgomery.

Research Wernerfelt’s work spans economics, marketing, and strategic management although he also has a few purely technical contributions. Most of his papers are single-authored and some break with the existing literature including “A Resource-Based View of the Firm”, “On the Nature and Scope of the Firm: An Adjustment-Cost Theory”, “A Rational Reconstruction of the Compromise Effect”, and “Why Should the Boss own the Assets?”. It suggests that differences in performance arise from variations in these resources and that strategy involves developing and using them over time.

Adaptation-Cost theory of the firm Wernerfelt's later work examines the economic theory of the firm. In The Comparative Advantages of Firms, Markets, and Contracts (2015), he analyzes when firms, markets, or contracts are more efficient. Building on earlier work from 1997, he highlights the role of small bargaining costs, arguing that when needs are varied and frequently changing, it may be more efficient to organize work by a relational quota contract under which the worker has agreed to follow orders without negotiation but can quit at any time.

In his 2016 book, Adaptation, Specialization, and the Theory of the Firm, he links this approach with the resource-based view, presenting them as consistent frameworks.

His more recent research includes work on organizational economics, signaling, and stochastic optimization, with publications continuing into the 2020s.
