At a Nash - Walras equilibrium, individuals exchange commodities competitively, and, simultaneously, they interact strategically. Under standard assumptions, NashWalras equilibria exist, equilibrium profiles of actions are, typically, determinate but Pareto suboptimal, though not constrained...

When n individuals satisfy the axioms of subjective expected utility (SEU) theory and these individuals' probabilities or/and utilities are sufficiently diverse, it is impossible to aggregate the individuals' preferences into a (n + 1)-preference which is both Paretian and in agreement with SEU...

When "n" individuals satisfy the axioms of subjective expected utility (SEU) theory and these individuals' probabilities or/and utilities are sufficiently diverse, it is impossible to aggregate the individuals' preferences into a (n+1)-preference which is both Paretian and in agreement with SEU...

The ethic of 'priority' is a compromise between the extremely compensatory ethic of 'welfare equality' and the needs-blind ethic of 'income equality'. We propose an axiom of priority, and characterize resource-allocation rules that are impartial, prioritarian, and solidaristic. They comprise a...

The veil of ignorance has been used often as a tool of recommending what justice requires with respect to the distribution of wealth. We complete Harsanyi's model of the veil of ignorance by appending information permitting objective comparisons among persons. We show that the veil-of-ignorance...

Properties of the demand of a large population introduced by the aggregation process are studied. The idea is to consider assumptions on the distribution of household characteristics rather than focusing on the modelling of individual behavior. By opposite to the existing literature where the...

This paper presents a simple two-country model with mobile capital and immobile labour, in which there are two classes of individuals, the workers and the capital owners. A source-based tax on capital income is used to finance transfers to workers. If the two countries are homogeneous in all...
