Abstract
The Gini concentration ratio as well as any other scalar measure of inequality is clearly inadequate as a description of the Lorenz curve. In this paper, a "dual" description, based on a measure of concentration and one of asymmetry (the Zanardi index) is advocated. Two applications are presented to show that the Gini and Zanardi indices capture the most significant aspects of a Lorenz curveFile in questo prodotto:
