On a Class of Inequality Measures
The parametric class of inequality measures examined in what follows contains, as extreme special cases, the inequality measures that are homogeneous of degree zero (concept of relative inequality) and those that leave inequality unchanged when all incomes, say, are increased by the same amount (concept of absolute inequality). The intermediate concepts studied here have the property that multiples of convex combinations of proportional and absolute changes (in all incomes) leave inequality unchanged.
