Recently, the authors have illustrated the decompositions by subpopulations of the Gini (1914), Bonferroni (1930) and Zenga (2007) inequality measures. These decompositions were illustrated by a numerical example involving non-overlapping subpopulations and by a numerical example involving overlapping subpopulations...

There is a great discussion concerning the differences between the income of females and males. The purpose of the present study is to estimate the distribution of the ratio of female income over male income. The methodology to study the ratio in exam is based on the distribution of the ratio of two Dagum random variables with three parameters proposed in 2010 by Pollastri and Zambruno...

Aim of this paper is to introduce the ‘‘global multipliers matrix’’ as a ‘‘structural’’ inequality measure of personal income distribution. This measure is derived from the Social Accounting Matrix, considered as a linear model. The multiplier approach allows quantifying the different ways by which, an income equally earned by each Household’s group, turns into different disposable income levels through the three stages of spending, production and distribution. The resulting inequality in personal income distribution can be considered as the minimum inequality compatible with the given productive and spending structures, and hence as a result of the mechanism explicitly considered in the model...

In this work, we propose to jointly analyse income and consumption distribution, using copula function to model the dependence structure, and the new formulation of Dagum distribution, proposed by Domma, Condino and Giordano (2018), to model the marginal distributions with a clear economic meaning of the marginal parameters...
