Amazon上的简介如下：“Fully revised and updated, this textbook provides a short and accessible introduction to the concept of economic inequality and how inequality can be modelled and measured. This edition is very much a "How to..." book relating to the measurement of inequality. It covers major new results about inequality rankings and inequality decomposition. A more technically oriented Appendix covers standard properties of inequality measures, provides properties of the most important functional forms, and summarizes the interrelationships amongst the key inequality measures. A data disk enclosed with the book includes key data sets on inequality and distribution. This text is intended for single and joint-honours economics students on the quantitative part of courses in Welfare Economics, Development Economics, Labour Economics and Public Sector Economics.”
