Inequality in Dual Economy Models

Gary Fields ()

Economic Journal, 1993, vol. 103, issue 420, 1228-35

Abstract: This paper seeks to make more precise the notion of inequality by asking how inequality ought to behave under certain kinds of income changes. These view are derived axiomatically from the Lorenz properties and from additional considerations of 'elitism of the rich' and 'isolation of the poor.' Although several alternative patterns are generated, six commonly used inequality measures accord with one particular inequality pattern. Inequality measures can be formulated to represent the other inequality patterns; a class of such measures is displayed. Copyright 1993 by Royal Economic Society.
