Title Nash Implementation in Production Economies with Unequal Skills: A Characterization
Author Naoki Yoshihara and Akira Yamada
Abstract The present study examines production economies with unequal labor skills, where the planner is ignorant of the set of feasible allocations in advance of production. In particular, we characterize Nash implementation by canonical mechanisms by means of Maskin monotonicity and a new axiom, non-manipulability of unused skills (NUS), where the latter represents a weak independence property with respect to changes in skills. Following these characterizations, we show that some Maskin monotonic social choice correspondences are not implementable if information about individual skills is absent.
