Should inequality comparisons with ordinal variables be sensitive to alternative sorting of the categories, i.e. ascending versus descending order? We introduce the consistency property whereby an inequality or bipolarisation index regards frequency distribution r less unequal than s if and only...

We propose a framework for the measurement of income mobility over several time periods, based on the notion that multi-period mobility amounts to measuring the degree of association between the individuals and the time periods in a contingency table. We provide both indices and a pre-ordering...
