The key challenge in making distributional comparisons with ordinal data is the lack of commensurability of the distances between the ordered categories. This chapter provides a critical review of the most recent theoretical developments addressing this challenge and providing methods for...

An aggregable family of multidimensional concentration indices is characterized, in order to be consistent with a property of exogenous risk factors, i.e. health risks for which agents are not responsible for. The family of concentration indices (or achievement indices by duality) lies in the...

We provide a critique of the standard methodology which bases welfare comparisons between households on deflating household income and consumption by an equivalence scale. We argue that this leads to support for tax/transfer policies that significantly disadvantage low to middle in-come...

When health status is an ordered response variable, Allison and Foster (2004) postulate that a distribution Q exhibits more inequality than a distribution P if Q isobtained from P via a sequence of median preserving spreads. This paper introduces aparametric family of inequality indices which...

Starting from the axiomatisation of polarisation contained in Esteban and Ray (1994)and Chakravarty and Majumdar (2001) we investigate whether people's perceptionsof income polarisation is consistent with the key axioms. This is carried out using aquestionnaire-experimental approach that...

We provide, for the class of relative bidimensional inequality indices, adecomposition of inequality into two univariate Atkinson-Kolm-Senindices and a third statistic which depends on the joint distribution ofresources
