The Economics of Inequality, Poverty, and Discrimination in the 21st Century consists of 2 volumes containing 32 papers divided into 5 categories: measurement, inequality and mobility, institutions and choices, demographic groups and discrimination, and policy. The papers-written by economists, sociologists, philosophers and lawyers-deal with the extent of inequality in the United States and how it compares to other countries, and the newly emerging evidence on the relationship between inequality and mobility within a society.
