In this paper we present some results for preference aggregation functionals defined on rich admissible sets. Our results are concerned with an Independence of Irrelevant Alternatives assumption due to Alan D. Taylor suitably adjusted to be applicable in the framework of preference aggregation...

In this paper we are concerned with the following question. Given an extended preference ordering under what conditions does there exist an empirical stochastic/social choice function which generates it? We use Farkas' lemma to obtain a necessary and sufficient condition under which such a...

We introduce the concept of a social choice functional and provide two axiomatic characterizations of the utilitarian social choice functional. Subsequently we consider Harsanyi's weighted utilitarianism and establish two more propositions concerning the same. While the first is an axiomatic...

In this paper a model for the aggregation of ballot profiles is considered.In this framework some new results are obtained:the characterization of the plurality aggregator and the non existence of a vote aggregator which is anonymous and yet preserves proximity
