This volume contains revised versions of the papers presented in 1971 at the Princeton University Conference on Discrimination in Labor Markets, and the formal discussions of them. This paper is by Kenneth Arrow, winner of the Nobel Prize in Economics, who lays the theoretical foundations of the economic analysis of discrimination in labor markets. Finis Welch discusses the relationship between schooling and labor market discrimination. Orley Ashenfelter's paper presents a method for estimating the effect of an important institution--trade unionism--on the wages of black workers relative to whites. Ronald Oaxaca provides a framework for measuring the extent of discrimination against women. Finally, Phyllis Wallace examines public policy on discrimination and suggests strategies for public policy in this area. Originally published in 1974. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.
