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...

We provide foundations for robust normative evaluation of distributions of two attributes,\r\none of which is cardinally measurable and transferable between individuals and the other is\r\nordinal and non-transferable. The result that we establish takes the form of an analogue to the standard...

We investigate the normative foundations of two empirically implementable dominance criteria for comparing distributions of two attributes, where the first one is cardinal while the second is ordinal. The criteria we consider are Atkinson and Bourguignon\'s (1982) first quasi-ordering and a...

We are interested in the comparisons of standard-of-living across societies when observations of both income and household structure are available. We generalise the approach of Atkinson and Bourguignon (1987) to the case where the marginal distributions of needs can vary across the household...
