Pareto optimal redistribution and private charity

Abstract

When private charity exists and is motivated by utility interdependence a non-Pareto optimal outcome, the ‘free-rider’ problem, typically arises. Nevertheless, incremental fiscal redistribution cannot achieve a Paretian welfare improvement so long as private charity continues at positive levels. Donors respond to incremental fiscal redistribution by reducing their voluntary contributions by exactly a dollar for every dollar transferred in this way. No net transfer is achieved unless incremental fiscal redistribution is pursued to the point where private contributions have been driven to zero. Alternatively, a net transfer may be achieved by fiscal measures which affect donors’ marginal incentives to donate. © 1982.
