Abstract

A fixed agenda social choice correspondence Ψ on outcome set X maps each profile of individual preferences into a nonempty subset of X. If Ψ satisfies an analogue of Arrow's independence of irrelevant alternatives condition, then either the range of Ψ contains exactly two alternatives, or else there is at most one individual whose preferences have any bearing on Ψ. This is the case even if Ψ is not defined for any proper subset of X.
