[eng] The Attitude to Inequalities in France Considering the Tax and Social Security Contributions System by Thibault Gajdos and Bertrand Lhommeau . Classic measurements of inequalities consider the collective aversion to inequalities to be an a priori fixed parameter. This paper proposes using tax data to build an indicator of inequalities that makes allowance for the collective attitude to inequalities. We use this indicator to measure income inequality trends in France from 1990 to 1997. Our analysis finds that the collective aversion to inequalities increased over this period, as shown primarily by a change in the tax and social security contributions policy. Hence, although the dispersion of disposable incomes remained fairly constant over the period in question, perceived inequalities would seem to have risen. [fre] Les mesures traditionnelles des inégalités considèrent l'aversion collective à l'égard des inégalités comme un paramètre déterminé a priori. Nous proposons ici d'utiliser les données fiscales pour construire un indicateur d'inégalités qui tienne compte de l'attitude collective à l'égard des inégalités. Nous utilisons cet indicateur pour mesurer l'évolution des inégalités de revenus en France entre 1990 et 1997. Il ressort de notre analyse que l'aversion collective à l'égard des inégalités a augmenté au cours de cette période, ce qui s'est essentiellement manifesté par une modification de la politique de prélèvements sociaux. Ainsi, bien que la dispersion des revenus disponibles soit restée à peu près constante sur la période considérée, les inégalités perçues auraient augmenté.
