Abstract

This paper shows that there does not exist a social choice function that satisfies strategy-proofness, Pareto-efficiency and equal treatment of equals simultaneously, in classical exchange economies. This result establishes the incompatibility of fairness and efficiency in strategy-proof social choice functions as found in Cho and Thomson (2013), which reaches the same conclusion for exchange economies with linear preferences.
