概要

In this paper, three approaches to generalizing the Hurwicz Theorem are surveyed. The first approach is literal generalization, which involves extending the number of agents and commodities to more than two. The second is composed of two steps: (1) proving that dictatorship is necessary for strategy-proofness in a general setting, and (2) invoking the fact that dictatorship is not individually rational. The third approach is to discoverwhat conditions are necessary and sufficient for strategy-proofness and individual rationality. Directions for possible future research are also presented.
