Approval Voting without Faithfulness
Year: 2013 Volume: 7 Issue: 1 Pages: 15-20
Abstract: In this short paper, we analyze the implications of dropping the axiom of faithfulness in the axiomatization of approval voting, due to P.C. Fishburn. We show that a ballot aggregation function satisfies the remaining axioms (neutrality, consistency and cancellation) if and only if it is either a function that chooses the whole set of alternatives, or an approval voting, or a function that chooses the least approved alternatives.
