Unit-Consistent Decomposable Inequality Measures
Abstract
This paper introduces a new axiom-the unit consistency axiom-into inequality measurement. This new axiom requires the ordinal inequality rankings (rather than the cardinal indices) to be unaffected when incomes are expressed in different units. I argue that unit consistency is an indispensable axiom for the measurement of income inequality. When unit consistency is combined with decomposability, I show that the unit-consistent decomposable class of inequality measures is a two-parameter extension of the one-parameter generalized entropy class. The extended class accommodates a variety of value judgments and includes different types of inequality measures. Copyright (c) The London School of Economics and Political Science 2006.Download Info
