About: Implementability (mechanism design)

An Entity of Type: Thing, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

In mechanism design, implementability is a property of a social choice function. It means that there is an incentive-compatible mechanism that attains ("implements")this function. There are several degrees of implementability, corresponding to the different degrees of incentive-compatibility, e.g: * A function is dominant-strategy implementable if it is attainable by a mechanism which is dominant-strategy-incentive-compatible (also called strategyproof). * A function is Bayesian-Nash implementable if it is attainable by a mechanism which is Bayesian-Nash-incentive-compatible.

dbo:abstract
  • In mechanism design, implementability is a property of a social choice function. It means that there is an incentive-compatible mechanism that attains ("implements")this function. There are several degrees of implementability, corresponding to the different degrees of incentive-compatibility, e.g: * A function is dominant-strategy implementable if it is attainable by a mechanism which is dominant-strategy-incentive-compatible (also called strategyproof). * A function is Bayesian-Nash implementable if it is attainable by a mechanism which is Bayesian-Nash-incentive-compatible. See for a recent reference. In some textbooks, the entire field of mechanism design is called Implementation theory. (en)
