In this paper, we propose the conception of Within-group Consumption-Dominance Curves in order to capture the impact of indirect tax reforms on poverty. Considering that the population is partitioned into many groups, which differ in needs, in health, in capability or other attributes, we...

For any given order of stochastic dominance, standard concentration curves are decomposed into contribution curves corresponding to within-group inequalities, between-group inequalities, and transvariational inequalities. We prove, for all orders, that contribution curve dominance implies...

In this paper, we propose the conception of within-group CD-curve, to apprehend the impact of indirect tax reforms on truncated distributions of consumption expenditures. This confers decision makers the ability to perform within-group transfers as well as between-group transfers to reduce...
