Les indicateurs de polarisation et leur application à la France

[fre] Cet article présente, dans un premier temps, les propriétés des indicateurs de polarisation des revenus, ceux de Foster-Wolfson et d’Esteban-Ray, leur portée et leur limite. Les deux critères de polarisation et d’inégalité apparaissent comme complémentaires mais distincts dans la mesure où le principe de transfert de Pigou-Dalton est étranger au concept de polarisation. Dans un second temps, l’application de ces indicateurs à des données françaises permet de tester leur portée explicative en comparant leur valeur informative à celle dérivée par une analyse plus fine des caractéristiques des populations. C’est l’occasion de s’interroger sur la pertinence du constat d’augmentation de la polarisation des revenus salariaux au cours des années quatre-vingt-dix. La polarisation des emplois semble avoir contribué significativement à ce phénomène. [eng] Polarisation Indicators and their Application to France. This article begins by presenting the properties of the income polarisation indicators developed by Foster-Wolfson and Esteban-Ray, and their scope and limits. The two polarisation and inequality criteria appear complementary but different insofar as the Pigou-Dalton transfer principle is alien to the polarisation concept. Wenext apply these indicators to French data in order to test their explanatory capacity by comparing their informative value with the results of closer analysis of population characteristics. We use this opportunity to look at the relevance of the increase in wage income polarisation in the nineties. Job polarisation appears to have made a significant contribution to this phenomenon.
