The achievements and limitations of the classical theory of optimal labor-income taxation based on social welfare functions are now well known, although utilitarianism still dominates public economics. We review the recent interest that has arisen for broadening the normative approach and making...

Nous proposons une méthode pour évaluer la capacité des systèmes de taxation du revenu de diminuer la pauvreté, lorsque celle-ci est définie en cohérence avec une notion de niveau de vie issue de l’éthique de la responsabilité. Selon cette éthique, toutes les inégalités ne sont pas...

We discuss and compare five measures of individual well-being, namely income, an objective composite well-being index, a measure of subjective well-being, equivalent income, and a well-being measure based on the von Neumann-Morgenstern utilities of the individuals. After examining the...

We propose a new class of multidimensional poverty indices. To aggregate and weight the different dimensions of poverty, we rely on the preferences of the concerned agents rather than on an arbitrary weighting scheme selected by the analyst. The Pareto principle is, therefore, satisfied among...

We model problems of allocating disputed properties as generalized exchange economies in which agents have preferences and claims over multiple goods, and the social endowment of each good may not be sufficient to satisfy all individual claims. In this context, we investigate procedural and...

We explore in this paper the axiomatic approach to the problem of sharing the revenue from bundled pricing. We formalize two models for this problem on the grounds of two different informational bases. In both models, we provide axiomatic rationale for natural rules to solve the problem. We,...

Standard models for the evaluation of population health, such as the so-called models of aggregate Quality Adjusted Life Years (QALYs), or aggregate Healthy Years Equivalent (HYEs), are usually criticized on equity grounds. We provide in this paper normative justifications for alternative...

Harsanyi (1955) proved that, in the context of uncertainty, social ratio- nality and the Pareto principle impose severe constraints on the degree of priority for the worst-off that can be adopted in the social evaluation. Since then, the literature has hesitated between an ex ante approach that...

The popular discounted utilitarian criterion for infinite horizon social choice has been criticized on the ground that it treats successive generations unfairly. I propose to evaluate intergenerational welfare with a rank- discounted utilitarian (RDU) criterion instead. The criterion amounts to...

Forgiveness is an ethical ideal that advocates that a fresh start should be conferred on those individuals who regret their past choices. Grounded on such a principle, Fleurbaey (2005) proposes the use of the equivalent endowment as the proper measure of the welfare loss experienced by those who...
