The Second Best Efficiency of Allocation Rules: Strategy-proofness and Single-peaked Preferences with Multiple Commodities
複数財を伴う単峰的選好の下での戦略的操作不可能な資源配分メカニズムの次善最適性について
概要:
(Abstract)
This paper studies the design of a strategy-proof resource allocation rule in economies with perfectly divisible multiple commodities and single-peaked preferences. It is known that the uniform rule is the unique allocation rule satisfying strategy-proofness, Pareto efficiency and anonymity if the number of commodity is only one and preferences are single-peaked (Sprumont(1991)). However, if the number of commodities is greater than one, the situation drastically changes and a trade-off between strategy-proofness and Pareto efficiency arises. The generalized uniform rule in multiple-commodity settings is still strategy-proof, but not Pareto efficient.In this paper, we show that in a class of all strategy-proof rules there exists a "second best" efficient strategy-proof rule in that there is no other strategy-proof rule which gives a "better" outcome than the rule in terms of Pareto domination for all preference profiles. In the proof of the theorem, Zorn's Lemma plays an important role. Furthermore, we show that the generalized uniform rule is second best efficient and we give a new characterization of the generalized uniform rule with the second best efficiency. That is, it is the unique rule satisfying the three axioms of the second best efficiency, peak-onliness and egalitarian rationality.We also show that three axioms are mutually independent.
