The aim of this paper is to survey and investigate the properties of the extended Gini family of inequality measures. The paper surveys the alternative ways of spelling the extended Gini for continuous distributions (such as via covariance, via Lorenz curves, etc), and the metrics that motivate...

Mobility implies initial and final distributions and a transition process linking the observations of these two distributions. An inequality index describes properties of the intitial or final distribution. A mobility index describes the transition. In most cases, mobility indices have been...

Polarization is a concept which is defined over the distribution of income. It is clear that it does not fit into the framework of the traditional Bergson-type Social Welfare Function. The aim of this paper is to investigate whether the concept can fit into the framework of the theory of...

The use of equivalence scales for the measurement of inequality and social welfare poses a difficult ethical and technical dilemma. If all individuals are weighted equally while individual welfare measures are based on income or consumption per equivalent adult, then standard properties assumed...

This note clarifies the relationship between beta-convergence and sigma-convergence in a univariate setting. In such a setting, sigma-convergence implies beta-convergence, but beta-convergence does not imply sigma-convergence. The results imply that caution should be used for the interpretation...
