POLARIZATION OF THE POOR: MULTIVARIATE RELATIVE POVERTY MEASUREMENT SANS FRONTIERS
A major impediment to poverty evaluation in environments with a multiplicity of wellbeing indicators is the difficulty associated with formulating a poverty frontier in many dimensions. This paper proposes two multivariate relative polarization measures which, in appropriate circumstances, serve as multivariate poverty measures which do not require computation of a poverty frontier. As poverty measures they have the intuitive appeal of reflecting the degree to which poor and non-poor societies are polarized. (The measures would also have considerable application in studying multivariate convergence issues in economic growth models.) The measures are exemplified in a poor-non-poor country study over the period 1990-2005, based upon the joint distribution of per capita GNP and Life Expectancy. The results suggest that as a group, the world's poor are experiencing diminished poverty polarization; however, within the world's poor the African nations are experiencing increased poverty polarization.
