Local Public Good Provision in Networks: A Nash Implementation Mechanism
In this paper we study local public goods provision in decentralized information networks. Local public goods are network users’ actions that directly affect the utilities of arbitrary subsets of network users. We consider networks where each user knows only that part of the network that either affects it or is affected by it. Furthermore, each user’s utility and action space are its private in...
متن کاملNash Implementation with Lottery Mechanisms
Consider the problem of exact Nash Implementation of social choice correspondences. De ne a lottery mechanism as a mechanism in which the planner can randomize on alternatives out of equilibrium while pure alternatives are always chosen in equilibrium. When preferences over alternatives are strict, we show that Maskin monotonicity (Maskin, 1999) is both necessary and su¢ cient for a social choi...
متن کاملRepeated 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...
