What do normative indices of multidimensional inequality really measure

摘要: We argue that normative indices of multidimensional inequality do not only measure a distribution’s extent inequity (i.e., the gaps between better-off and worse-off), but also its inefficiency non-realized mutually beneficial exchanges goods). provide decomposition allows quantifying these two parts inequality. Exact formulas components are provided for generic class social welfare functions. The component turns out to be two-stage measure, which applies unidimensional vector well-being levels. critically discuss prominent transfer principles, viz., uniform majorization correlation increasing majorization, in light decomposition. A human development illustrates analysis.
