Parti yapısıyla uygulanabilirlik

In this study party implementation concept is introduced. Party implementationis an extension of classical implementation allowing different parties tohave group-specific choice rules. Members of a party are assumed to act cooperativelyaccording to a common preference. In this context, a choice ruleis said to be party implementable if it is robust to co-operative manipulation.In this thesis some necessity and sufficiency results for party implementationis proven. In particular, it is shown that under some restrictions if the societieschoice rule is party implementable, an alternative that is chosen by anygroup should also be chosen by the society. Moreover, it is shown that if thecollective choice can be represented by the union of different groups' choice,then the social choice rule should be party implementable.
