Abstract

Les mesures d’inégalité du revenu rassemblent deux types d’indicateurs décomposables : les indices décomposables en sous-populations et les indices décomposables en sources de revenu. Les premiers permettent de partager l’inégalité totale en une inégalité intragroupe et une inégalité intergroupe et les seconds d’attribuer à chaque facteur de revenu (revenu du travail, revenu du capital, taxes, etc.) une part de l’inégalité totale. Dans cet article, nous examinons d’une part la construction de ces techniques et d’autre part nous relatons les débats auxquels elles ont abouti et plus particulièrement celui de la convergence vers un emploi simultané des deux types de décomposition.
