Joel Dean (1906 - 1979) is best known for his contributions to Corporate Finance theory in general, and particularly to the area of Capital budgeting [1]. He is regarded as one of the founders of business economics. His work on pricing remains influential in marketing [2], although his related work on cost curves has been largely ignored by economists.



Dean was born in Vershire, Vermont and educated at Pomona College (A.B. 1927), Harvard Business School (MBA, 1928) and at the University of Chicago (Ph.D, 1936). His doctoral dissertation discussed "A Statistical Examination of the Behavior of Average and Marginal Cost" .[1] He was one of the founders of business economics with his Managerial Economics (1951). [3] and Capital Budgeting(1951) [4]

His research covered costs, pricing, demand analysis, profits and profit management, and also competition and government regulations. [1] It was with the publication of his "Capital Budgeting" in 1951 [5] that NPV became widely used in corporate finance [6]

He taught at Indiana University, the University of Chicago, and Columbia University. During world war II he was with the Office of Price Administration, and was also a research associate of the Cowles Commission. In 1940 he founded Joel Dean Associates, a management consulting firm. He was on the editorial boards of the Journal of Industrial Economics and the Journal of Marketing for many years.

Cost functions

Dean discovered [7] [8] that cost functions of firms are often straight line as opposed to S-shaped functions [9] a fact which disagreed with the classical assumption in microeconomics (which had not been based on observation). [10]

It is thought that Dean's observation was ignored by the mainstream economists, for it required a revolutionary change in microeconomic theory: if the cost function of a firm is linear, then the total variable cost is proportional to the production volume and the marginal cost is constant, in which case the usual formula "price = marginal cost" fails, and the common explanation as to why the supply curve is an increasing function of the market price also fails.

Selected works

Joel Dean's best known work is Capital Budgeting (New York: Columbia University Press, 1951. ISBN 0231018479). His Statistical Cost Estimation (Indiana University Press, 1976), by contrast, is a forgotten book, perhaps for the reasons outlined above.

Other publications include:
