Sen and the collective choice

Between Arrow and Sen there are two types of rupture. The first, in coherence with the founding premises of the impossibility theorems of Arrow, shows that it is feasible to find consistent processes of collective choice, as long as one is willing to give up axiomatic "puri ty". The second places Sen on very different ground than Arrow. Sen makes explicit the goodness of interpersonal comparisons and does not hide his sympathies for cardinal mea sures of utility and welfare. He shows that if we accept that an individual j decides taking into account the welfare he would experience in the case of finding himself in situation x of a person i, then there is no other alternative than to make explicit the criterion of justice that underlies all collective choice.
