Multidimensional Inequality and Human Development

Abstract

The measurement of inequality from a human development perspective is fundamental. We start this paper by briefly introducing the human development approach and its main conceptual basis: the capability approach. We note that inequality should preferably be assessed in the space of functionings, requiring the assessment methods to use multidimensional techniques. We then present the primary challenges inherent to multidimensional inequality measurement that are related to two types of distributional changes: one is concerned with the dispersions within distributions that are analogous to the unidimensional framework and the other, unlike the unidimensional framework, is concerned with the association between distributions. We next present a succinct review of the most prominent measures proposed in the literature within a unifying framework and review the empirical applications surrounding these measures. We note that while multidimensional inequality measures have a great potential to contribute to the monitoring of human development, there are some challenges to overcome in order to fulfil this potential.
