Public Choice Interpretations of Distributional
Preference'
HAROLD M. HOCHMAN
Department of Economics, Lafayette College, Easton, Pa. 18042
Abstract. This essay examines, from the perspective of both economics and ethics, the logical foundations of
income transfers in a democratic society that allocates resources, in the large, through free markets. Such transfers,
enacted through the public choice process, modify the market-determined distribution of income, as a reflection of
the distributional preferences of the members of a society. Both constitutional and post-constitutional explanations
of redistributions are considered. A discussion of recent experimental evidence of distributional preferences leads
into a critique of simple equality, built on Michael Walzer's distinction between monopoly and dominance, as a
criterion of distributive justice.

1. Introduction: Economics and Ethics
For nearly three decades I have puzzled and, on occasion, written about the logical founda-
tions of income transfers, intended to modify the market-determined distribution of income,
to effect income redistribution in a democratic society that allocates resources through free
markets.2 Unlike most writings on this subject, however, my analysis is grounded in the
distributional preferences of individuals and voting blocs, as these are revealed, politically,
through fiscal redistribution, and not on the details of actual redistributive programs. Im-
plicitly, then, my concern has been with the intricate and troubled relationship of political
economy, in its neoclassical incarnation, to ethics.
Profoundly moral issues of this genre were central to the writings of Adam Smith and
John Stuart Mill, and later for writers as diverse as Marx and Friedman or von Hayek.
Substantively, this essay is a selective review of what economists have learned about distri-
butional principles, by employing the methods of public choice, over the last generation.3
The focus is on issues of equity or fairness, in particular, on the puzzling reality that most
people do support redistributive transfers through private or political behavior, even when
they seem to lose financially as a result.4 Since such questions draw us, inevitably, on to
other terrain, I shall refer liberally, though perhaps less than faithfully, to contemporary
political philosophy.
The argument will have an admittedly subjective cast. Extended to distributional prefer-
ence, economic discussion can be neither morally antiseptic nor ahistorical. Values are an
intricate product of culture, teachers, faith, and personal history; introspection and a sense
of the past, especially one's own, not only condition critical capacities, but shape analysis.
Whether the argument that results can be defined as science is moot. Theory is never a
failsafe guarantor of objectivity, much less common sense; this is especially true for topics
like equality, property, and social justice, where the key to saying something meaningful
