Global inequality: a multidimensional perspective.

Abstract

This paper investigates the evolution of global well-being inequality between 1980 and 2010 based on three dimensions: income, health and education. The inequality of each of these dimensions shows a different pattern over time. To make an overall assessment of the evolution of well-being inequality, I make use of a recently developed multidimensional inequality index which reflects the implicit value judgments of the revised Human Development Index. Multidimensional well-being inequality has decreased over the considered period. However, this result is shown to depend crucially on the weighting scheme selected, the aggregation procedure and the transformation of the income dimension.
