''Extending Xu's results to Arrow''s Impossibility Theorem'' |

This note shows that results similar to Arrow's Impossibility Theorem can be proved by replacing the weak Pareto principle by a weaker condition called Pareto Neutrality and used by Xu (1990) to state another version of Sen''s liberal paradox. Our result strengthens Xu''s arguments for taking into account non-welfarist information into the social-choice-theoretic framework. |
