Repeated Nash implementation
We study the repeated implementation of social choice functions in environments with complete information and changing preferences. We define dynamic monotonicity, a natural but nontrivial dynamic extension of Maskin monotonicity, and show that it is necessary and almost sufficient for repeated Nash implementation, regardless of whether the horizon is finite or infinite and whether the discount...
متن کاملImminent Nash Implementation∗
We introduce delay in simultaneous-move mechanisms. Delay is infinitesimal in equilibrium, hence the name: imminent implementation. We show that mechanisms with delay implement rules that are not implementable without delay in Nash equilibrium and its refinements. We obtain a version of the monotonicity condition that is necessary and sufficient for imminent implementability. If the domain incl...
متن کاملNash implementation via hyperfunctions
Hyperfunctions are social choice rules which assign sets of alternatives to preference profiles over sets. So, they are more general objects compared to standard (social choice) correspondences. Thus every correspondence can be expressed in terms of an equivalent hyperfunction. We postulate the equivalence between implementing a correspondence and its equivalent hyperfunction. We give a partial...
متن کاملRepeated Implementation
In the traditional static implementation literature it is often impossible for implementors to enforce their optimal outcomes. And when restricting the choice to dominant-strategy implementation, only the dictatorial choices of one of the participants are implementable. Repeated implementation problems are drastically different. In this paper we provide an implementation “folk theorem”: for pat...
متن کاملRepeated Implementation ∗
We prove that a social choice function is repeatedly implementable if and only if it is dynamically monotonic when the number of agents is at least three. We show how to test dynamic monotonicity by building an associated repeated game. It follows that a weaker version of Maskin monotonicity is necessary and sufficient among the social choice functions that are efficient. As an application, we ...
