This note proposes a relative bipolarization quasi-ordering based on Between-Group Gini (BGG) curves, which is consistent with the quasi-ordering generated by relative bipolarization indices satisfying key axioms. Therefore the quasi-ordering induced by BGG curves is identical to the one induced...

Bennett and Hatzimasoura (2011) derive a new class of poverty measures suitable for ordinal variables. These indices are weighted sums of the population probabilities of attaining each state of the ordinal variable which is below the poverty line. The weights are uniquely determined by the...

When measuring poverty with counting measures, are there conditions ensuring that poverty reduction not only reduces the average poverty score further but also decreases deprivation inequality among the poor more, thereby emphasizing improvements among the poorest of the poor? In the case of a...

A natural concern with multivariate poverty measures, as well as with other composite indices, is the robustness of their ordinal comparisons to changes in the indices’ parameter values. Applying multivariate stochastic dominance techniques, this paper derives the distributional conditions...
