Consider the following nine rules for adjudicating conflicting claims: the proportional, constrained equal awards, constrained equal losses, Talmud, Piniles’, constrained egalitarian, adjusted proportional, random arrival, and minimal overlap rules. For each pair of rules in this list, we...

The unidimensional Pigou-Dalton transfer principle demands that a regressive transfer in income--a transfer from worse-off (poor) to better-off (rich)--decreases social welfare. In a multidimensional setting the direct link between income (or any other attribute) and individual well-being is...

The ethical view of prioritarianism holds the following: if an extra bundle of attributes is to be allocated to either of two individuals, then priority should be given to the worse off among the two. We consider multidimensional poverty comparisons with cardinal and ordinal attributes and...

We propose a criterion to rank poverty measures on the basis of distribution-sensitivity. The criterion compares reactions to ‘lossy’ transfers among the poor. We focus on the class of rank-dependent poverty measures and provide distribution-sensitivity rankings of the poverty gap ratio, the...

We argue that normative indices of multidimensional inequality do not only measure a distribution’s extent of inequity (i.e., the gaps between the better-off and the worse-off), but also its extent of inefficiency (i.e., the non-realized mutually beneficial exchanges of goods). We provide a...

type="main" xml:id="ecca12059-abs-0001" <p>We study the evolution of population-weighted between-country inequality in the period 1980–2009. Whereas previous studies almost exclusively focused on relative inequality measures, we consider relative, absolute and intermediate versions of the Lorenz...</p>

We provide a parsimonious axiomatisation of the complete class of absolute nequality indices. Our approach uses only a weak form of decomposability and does not require a priori that the measures be differentiable.

A particular scale-invariant index of poverty is subjected to careful analysis. This leads to a new perspective, not seen before, on the family of subgroup-consistent and scale-invariant poverty indices. Parametric families of new poverty indices are presented which offer the analyst a degree of...
