A new concept of Lorenz domination

We introduce in this paper a new criterion for evaluating the inequality of incomes that is consistent and is implied by the unanimous partial order generated by the class of absolute inequality indexes introduced by Kolm (1976). The corresponding ranking is shown to be easily implementable through pairwise comparisons of absolute Lorenz curves. Absolute Lorenz curves are related to generalized Lorenz curves introduced by Shorrocks (1983) and are furthermore amenable to an intuitively appealing interpretation.
