Stochastic dominance has been typically used with a special emphasis on risk and in-equality reduction something captured by the concavity of the utility function in the expected utility model. We claim that the applicability of the stochastic dominance ap-proach goes far beyond risk and...

We show that it is possible to reconcile the utilitarian and welfarist principles under the\r\nrequirement of unanimity provided that the set of profiles over which the consensus is\r\nattained is rich enough. More precisely, we identify a closedness condition which, if satisfied\r\nby a class...

In this article, we propose to extend the concept of stochastic dominance, extensively used in decision theory and social choice, to the comparison of composite outcomes, both the quality and quantity of which do matter. Unanimity of judgment among new classes of functions is also studied. We...
