Recently, Hermandez-Lamoneda et al. (2008) and independently Chameni and Andjiga (2008) gave an analytic formulation for all valued solutions to the n-person TU-games that satisfy linearity, efficiency and symmetry axioms. Our main purpose in this paper is to recast the proposed formulation to a...

This article proposes a simultaneous (income source and population subgroup) decomposition of inequality indices. The starting point is the Shorrocks' natural income source decomposition. The approach adopted leads to a factor contributions formula, which is independent of the inequality measure...

This research proposes a new decomposition of the Hirschman-Herfindahl index (which is equal to half the square of the coefficient of variation) into subgroup and income source. The method for decomposing into subgroups is similar to that used by Dagum when decomposing Gini's index. This...
