Abstract: | Abstract. For any given order of inverse stochastic dominance, standard concentration curves are decomposed into three components, called contribution curves. Those components correspond to within‐group inequalities, between‐group inequalities, and transvariational inequalities. We prove, for all orders, that contribution curve dominance implies systematically welfare‐improving tax reforms and conversely. Accordingly, as welfare expansions may be costly in terms of particular inequalities, we propose targeted fiscal reforms. |
