An elementary characterization of the Gini index Article uri icon


  • The Gini index is one of the most used indicators of social and economic inequality. In this paper we characterize the Gini index as the unique function that satisfies the properties of scale independence, symmetry, standardization and comonotone separability. Furthermore, we propose a simpler way to compute it. © 2015 Elsevier B.V.
