We propose an extension of Harsanyi's Impartial Observer Theorem based on the representation of ignorance as the set of all possible probability distributions over individuals. We obtain a characterization of the observer's preferences that, under our most restrictive conditions, is a convex...

Most prominent models of economic justice (and especially those proposed by Harsanyi and Rawls) are based on the assumption that impartiality is required for making moral decisions. However, although Harsanyi and Rawls agree on that, and furthermore agree on the fact that impartiality can be...

The paper shows that, when dealing with social justice, it is necessary but not sufficient to consider the social evaluator as placed behind a veil of ignorance. Then, her judgements are conform to the moral principle of universalisation and thus are impartial. But the way such judgements should...

[fre] Pour rendre compte du comportement rationnel d'ordre éthique, Harsanyi reprend la figure du spectateur impartial de Smith. Or, des différences significatives apparaissent, entre les deux auteurs, concernant le traitement du jugement moral. Chez Harsanyi, il s'agit d'un jugement...

Sen opposes two approaches to social justice. The transcendental one deals with the question of a just society. The comparative approach is about ordering social alternatives. According to Sen, such approaches are exclusive. I discuss the argument and show that the approaches are complementary....

The purpose of this note is to build an ethical inequality index which explicitely takes into account the social attitude towards inequlaity, through the actual tax scheme. We give a rough empirical application of this subjective inequality index to the evolution of wage inequality in France...
