The Structure of Earnings and the Measurement of Income Inequality in the U.S.

The various issues involved in measuring income inequality in the U.S. are analyzed in this book. In describing the level of inequality inherent in a particular graduation it is important which income recipient and which data set is used and also the measure of income inequality used as the appropriate summary statistic.Recent trends in labor markets are examined and the book attempts to trace the impact of these trends on the distribution of income for various age, race and occupational cohorts, and across states. Some new methods for analyzing inequality in a multidimensional framework are also discussed. This book provides one of the most comprehensive treatments of income inequality available to date.
