Nous etudions dans un modele a generations avec altruisme imparfait la distribution de la richesse de long terme ainsi que les inegalites sociales qu'elle engendre. Puis nous introduisons successivement dans le modele deux types de politique fiscale redistributive: une taxation des heritages et...

Nous montrons à l’aide de l’enquête Logement que les personnes d’origine africaine sont surreprésentées dans les grandes agglomérations et tendent à s’y fixer dans des proportions beaucoup plus importantes que les personnes d’origine française. Deux raisons expliquent ce...

This paper examines the normative properties of an empirically implementable dominance criterion for comparing alternative distributions of two attributes, one of which being cardinally measurable, between an arbitrary number of individuals. The criterion, which generalizes the one proposed by...

This paper examines how allowing individuals to emigrate to pay lower taxes changes the optimal non-linear income tax scheme in a Mirrleesian economy. Type-dependent participation constraints are borrowed from contract theory. An individual emigrates if his domestic utility is less than his...

Consider a developing country that has the potential for biodiversity conservation, and developed countries that benefit from biodiversity but are not in position to produce it. From the statu quo, some incremental protections of biodiversity would be harmful for the developing country but would...

inequality decreases and welfare increases as a result of a progressive transfer. We explore the implications for welfare and inequality measurement of substituting the weaker absolute differentials and deprivation quasi-orderings for the Lorenz quasi-ordering. Restricting attention to...

Under perfect observation of incomes, designing such scheme boils down to solving an optimisation program under constraints, which can be achieved with well-defined methods. In contrast, when incomes cannot be perfectly observed, the schemes are usually based on predictions of living standards...

The universal moral public good of fighting poverty is provided by both public and private transfers. Efficient public transfers do not crowd out giving because of the particular motives for it. Understanding these effects is necessary for both explaining aid and choosing policy. This analysis...
