Forthcoming in the AER: "Social Preferences over Ordinal Outcomes" by Sandro Ambuehl and B. Douglas Bernheim.
(Forthcoming Article) - We study social preferences in settings where someone who chooses on behalf of others knows
how those individuals rank the available options but may lack cardinal information concerning
those comparisons. Contrary to majoritarian principles, most people place more weight on pre-
venting least-preferred outcomes for others than on enabling most-preferred outcomes. Ranks
matter both intrinsically and because they provide a basis for inferring cardinal utility. Ordinal
aggregation principles are stable across domains and countries with divergent political traditions.
Designing attractive social choice mechanisms is challenging in practice partly because aggre-
gation principles that make manipulation diffcult yield outcomes people consider normatively
unappealing.
