This article introduces a new matrix approach, based on pairwise income comparisons, to decompose the Atkinson-Plotnick-Kakwani re-ranking measure when income units are gathered into groups. As it is known the Atkinson-Plotnick-Kakwani re-ranking measure is defined by the difference between the...

In this paper we reconsider the Dagum decomposition of the Gini index and we compare this decomposition with the decompositions proposed by Mookherjee and Shorrocks and by Lambert and Aronson. In so doing, a deeper insight into the meaning of the overlapping term is given and an alternative...

Existing methods of between-groups income inequality measurement are rather uninformative if applied to genders since they are not sensitive to discrimination. We introduce a Gini-based measure of between-genders inequality which explicitly depends upon discrimination and we apply it to measure...

Traditionally, the literature has seen stratification as linked closely to within-group inequality. More recently, some papers have focused on measuring the impact of stratification on betweengroup inequality. In this paper, we show that when two groups are involved, such an impact can be...
