In this paper, taking as starting point the link between polarization and dispersion, we reformulate the measure of polarization of Zhang and Kanbur (2001) using the decomposition of the variance instead of the decomposition of the Theil index. The proposed measure is equivalent to the...

In this paper, it will be shown that polarization not only depends on identification and alienation. There exist additional factors such as the share of power held by each of the groups and the number of groups that should be considered to compute it. Consistent with this idea and with the basic...

In this paper we apply the methodology developed by García-Fernández and Palacios-González (2008,2009) based on multiresolution analysis, to the measurement of polarization to Israeli income data over the past decade. This methodology allows us, in contrast to other polarization measures, to...
