Reviews / Votes
"I regularly teach a course on inequality, most recently using the developing manuscript of Ed Wolff's revised text. This work comprehensively (and fascinatingly) covers the central topics of poverty and of income and wealth distribution. I plan to use it for years to come." Frank Thompson, University of Michigan-Ann Arbor "The text is clearly written, with a comprehensive and up-to-date coverage and summarization of a very wide range of literature." Lars Osberg, Dalhousie University"I would certainly use this text in my income distribution course. It is much more comprehensive and useful than anything else on the market, and provides the foundation for an engaging and interesting course." Michael Sattinger, SUNY Albany
"Students will benefit from this text's broad coverage of empirical evidence on the distribution of income and wealth, its clear description of the technical measures of inequality, and its easily accessible language." Dean Lillard, Cornell University
"The quality of this text is outstanding, both as a textbook and as a reference for professional economists." Keith Bender, University of Wisconsin-Milwaukee
"Wolff's expertise in the study of wealth and inequality is evident in his meticulous provision of interesting and informative footnotes and the comprehensive nature of the coverage. The textbook has enough introductory material for the typical sophomore in college. At the same time, Wolff provides a substantial dose of more advanced material to satisfy and challenge upper-level students with superior background or capability in economics." Wendy Rayack, Wesleyan University
