The writing and reception of Risk, Uncertainty and Profit

Research output: Contribution to journalReview articlepeer-review

2 Scopus citations


Risk, Uncertainty and Profit was published in 1921, but started as the doctoral thesis 'A Theory of Business Profit,' defended in 1916. The first half of the paper examines the changes in organization and argument that Knight undertook between completing the thesis defense and the book's publication five years later. The reorganization helped Knight focus attention on uncertainty as the most important aspect of economic life standing between the worlds of perfect and imperfect competition, and to explore more of its implications for both price theory and entrepreneurial judgment. The second half of the paper carries the story forward by examining the reception Risk, Uncertainty and Profit received from 1921 until Knight's retirement in the early 1950s. The study of its reception uses a database of citations of Knight's book in economics journals found through a JSTOR search. While Knight's book is remembered today mostly for its introduction of uncertainty, in the economics literature the book's treatment of basic price theory is more frequently cited, especially in the leading economics journals of the interwar period. The citation data indicates that the role of Risk, Uncertainty and Profit in economics education at the London School of Economics and the University of Chicago extended and expanded the book's impact.
