The Lorenz curve and Gini coefficient are applied here to measure and graph disproportionality in outcomes for multiseat elections held in 2017. The discussion compares Proportional Representation (PR) in Holland (PR Gini 3.6%) with District Representation (DR) in France (41.6%), UK (15.6%) and...

This paper investigates the income inequality generated by a jobsearch process when different cohorts of homogeneous workers are allowed to have different degrees of impatience. Using the fact the average wage under the invariant Markovian distribution is a decreasing function of the discount...

The standard approach to inequality measurement regards all inequalities as being unfair. However, most people do not share this view, and believe that some inequalities are fair. This paper shows one way of generalizing the standard approach to take account of the distinction between fair and...

Caste is arguably one of the most important factors that determines social and economic outcomes in India. Few studies, however, have systematically examined caste-based inequality comparatively. This note measures contemporary levels of caste inequality in Indian states by conceptualizing...

There is a vast literature on the selection of an appropriate index of income inequality and on what desirable properties such a measure (or index) should contain. The Gini index is, of course, the most popular. There is a concurrent literature on the use of hypothetical statistical...

This paper introduces in statistics the notion of the barycenter of the distribution of a non-negative random variable and explores its relation with the Gini index, the concentration area, and the Gini’s mean difference. The introduction of the barycenter allows for new economic, geometrical,...

The inequality dataset compiled in the 1990s by the World Bank and extended by the United Nations has been both widely used and strongly criticized. The criticisms raise questions about conclusions drawn from secondary inequality datasets in general. The authors develop techniques to deal with...
