We provide an axiomatic justification to aggregate money metrics. The key axiom requires the approval of richer-to-poorer transfers that preserve the overall efficiency of the distribution. This transfer principle - together with the basic axioms of anonymity, continuity, monotonicity, and a...

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...

In a model in which agents differ in wages and preferences over labor time-consumption bundles, we study labor income tax schemes that alleviate poverty. To avoid conflict with individual well-being, we require redistribution to take place between agents on both sides of the poverty line...

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 investigate whether the simple plurality rule aggregates information efficiently in a large election with three alternatives. The environment is the same as in the Condorcet Jury Theorem (Condorcet (1785)). Voters have common preferences that depend on the unknown state of nature, and they...
