Ethical inequality measures and the redistribution of income when needs differ


The paper considers nested social welfare functions and ethical inequality measures when households may differ in needs. Several principles of transfers between different household types are introduced and systematically examined. Their implications for the form of welfare functions and inequality measures are derived. The corresponding classes are completely described.
