This paper attempts to devise a methodology that allows estimating the exact impact of training on the dispersion of wages. The approach is derived from a decomposition technique recently proposed by Fields (2003). It extends Fields' approach by taking into account population subgroups and...

Traditional indices of bi-dimensional inequality and polarization were developed for cardinal variables and cannot be used to quantify dispersion in ordinal measures of socioeconomic status and health. This paper develops two approaches to the measurement of inequality and bi-polarization using...
