Assessing Inequality

Assessing Inequality

May 2010 | 160 pages | SAGE Publications, Inc

Providing basic foundations for measuring inequality
from the perspective of distributional properties

This monograpg reviews a set of widely used summary inequality measures, and the lesser known relative distribution method provides the basic rationale behind each measure and discusses their interconnections. It also introduces model-based decomposition of inequality over time using quantile regression. This approach enables researchers to estimate two different contributions to changes in inequality between two time points.

Key Features

  • Clear statistical explanations provide fundamental statistical basis for understanding the new modeling framework
  • Straightforward empirical examples reinforce statistical knowledge and ready-to-use procedures
  • Multiple approaches to assessing inequality are introduced by starting with the basic distributional property and providing connections among approaches

This supplementary text is appropriate for any graduate-level, intermediate, or advanced statistics course across the social and behavioral sciences, as well as individual researchers.
