Abstract: The purpose of this paper is to extend Dagum’s Gini decomposition (“A New Approach to the Decomposition of the Gini Income Inequality Ratio”, Empirical Economics 22(4), 515-531, 1997a) following three types of theoretical modelisation. The first one deals with a “poor/non-poor” decomposition within a sub-group multilevel framework. The second one exhibits the multi-decomposition technique, that is, the combination of the sub-group and the income source decomposition. Finally, we provide a parametric multi-decomposition in order to capture different dimensions of income inequality within groups and between groups.
