In this paper we apply two statistical models to the measurement of polarization to Israeli income data over the past decade in order to empirically detect income classes as sub-populations of incomes concentrated around an optimal number of poles. The statistical models compared are a...

Despite a strong theoretical prediction that income skewness and redistribution should be positively linked, empirical evidence on this issue is mixed. This paper argues that it is important to distinguish between sources of changes in income skewness. Two sources of such changes are discussed:...

This paper proposes a concept of inequality comparisons with ordinal multidimensional categorical data. In our model, one population is more unequal than another when they have common arithmetic median outcomes and the first can be obtained from the second by correlation-increasing switches...
