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...

This paper presents an axiomatic model of decision making which incorporates objective but imprecise information. We axiomatize a decision criterion of the multiple priors (or maxmin expected utility) type. The model achieves two primary objectives. First, it explains how subjective belief...

We provide a model of decision making under uncertainty in which the decision maker reacts to imprecision of the available data. Data is represented by a set of probability distributions. We axiomatize a decision criterion of the maxmin expected utility type, in which the revealed set of priors...

We provide a general theorem on the aggregation of preferences under uncertainty. We study, in the Anscombe-Aumann setting a wide class of preferences that includes most known models of decision under uncertainty (and state-dependent versions of these models). We prove that aggregation is...

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...
