L’économie des inégalités est une partie non négligeable de l’économie publique et du domaine de la justice sociale. Pour apprécier l’efficacité d’un principe de justice sociale (commutative, distributive, locale, etc.), les mesures d’inégalité sont souvent utilisées. Elles...

[eng] The inequalities of net annual wages, estimated via the Gini ratio, declined by about 8 % between 1976 and 2000. The indicator fell from 0.322 to 0.296. By using the Gini decomposition and dividing the French population by age group, gender, occupational category, and geographic area, we...

We propose a generalization of the decomposition by population subgroups of the α-Gini index, the so-called multi-level subgroup decomposition. We demonstrate that all components obtained from the decomposition, can integrate in their functional form a parameter of inequality sensitivity being...

This article shows that the multidimensional Gini index is more complete than its unidimensional configuration in order to compute the contribution of each group to the overall inequality. In Languedoc-Roussillon, it indicates that the disparities are particularly generated by wage differences...

[eng] In the second half of the period 1961-2000, the unemployment rate trended down in the United States and the United Kingdom, and trended up steadily in Germany, France, and Italy. Can we explain this divergence by assuming that the impact of wage demands on the value-added breakdown was...

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