We show in this paper that the growth rate of the Sen index is multi-decomposable, that is, decomposable simultaneously by groups and income sources. The multi-decomposition of the poverty growth yields respectively: the growth rate of the poverty incidence (poverty rate) decomposed by groups,...

Afin de lutter contre le chômage « ...qui, en dehors de courts intervalles d’emballement, est une conséquence, et à notre avis une conséquence inévitable, de l’individualisme tel qu’il apparaît dans le régime capitaliste moderne. » (Keynes J.M., 1968, p. 394-395), Keynes propose...

Four axioms are introduced in order to characterize the family of pair-based decomposable inequality measures, which is embraced in the class of weakly decomposable inequality measures. Three axioms, namely, normalization by pairs, aggregation by pairs, and decomposition by pairs enable the...

In most welfare analyses, especially in the literature on normative inequality measurement, it is a commonplace to assume a direct relationship between the distribution of income and social welfare. As a result, this relationship is formally summarized by a single function, called a reduced-form...

In this paper, we investigate the analytical links between the rate of unemployment, monetary creation and how individuals share the value added in an economy with three types of agents : capital owners, managers and employees. This relationship relies on the fact that the rate of unemployment...

Following Milanovic's (1997) paper [Economics Letters, vol. 56, p. 45-49], we propose a simple way to compute the Gini index when income y is a quadratic function of its rank among n individuals.

La littérature montre que la mesure des inégalités de revenu n’est pas suffisante pour appréhender les déterminants des inégalités. Les sources de rémunération, leurs corrélations au revenu global, leurs parts dans le revenu global, rentrent en compte dans la décomposition de la...

This paper introduces the concept of Pigou-Dalton transfers between populations of income receivers. Gini's mean difference and Dagum's Gini index between populations are axiomatically derived in order to gauge the impact of within- and between-group Pigou-Dalton transfers on Dagum's measure. We...

Nous proposons une nouvelle méthode de décomposition. La multidécomposition de l’indicateur de Gini combine deux méthodes de décomposition : la décomposition en sous-groupes et la décomposition en sources de revenu. La technique retenue est mise en oeuvre dans le cadre d’une étude...

This paper proposes many indicators of vertical and horizontal redistribution throughout a generalized technique of Gini decomposition. Using the TD/BU micro-simulation models with externalities, we simulate income distributions and income source distributions for seven educational groups in...
