Abstract
Altres ajuts: ECO2016-75623-RThis paper holistically adressthe effective (relative) income tax contribution of a given income (or wealth) group. The widely acclaimed standard in public policy is the absolute benefaction of a given income group in filling up the fiscal coffers. Instead, we focus on the ratio of the average income tax rate of an income group divided by the percentage of national income (or wealth) appropiated by the same income group. In turn, we develop the Fiscal Inequality Coefficient wich compares the effective percentage income tax payments of pairs of income (or wealth) groups. Using data for the US, we concentrate on pairs such as the Bottom 90? versus Top 10%, Bottom 99% versus Top 1% and Bottom 99.9% versus Top 0.1%. We conclude that policy makers with strong social conscience should re-evaluate the progresivity of the income tax system and make the richest echelons of the income and wealth distributions pay a fairer and higher tax
