Consider an income distribution among households of the same size in which individuals, equally needy from the point of view of an ethical observer, are treated unfairly. Individuals are split into two types, the dominant and the dominated. We look for conditions under which welfare and...

Consider an income distribution among households of the same size in which individuals, equally needy from the point of view of an ethical observer, are treated unfairly within the household: an individual is systematically disadvantaged in the intra-household allocation. If an improvement of...

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 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...

We offer a model of equality of opportunity that encompasses different conceptions expressed in the public and philosophical debates. In addition to circumstances whose effect on outcome should be compensated and effort which represents a legitimate source of inequality, we introduce a third...

When equivalence scales are used to compute the well-being of individuals, two possible weighting methods of the different household types have been proposed, the first one resorts to the family size and the second to the equivalence scale itself. The latter is criticized on the ground that it...

Properties of an average voting rule - the outcome being some weighted average of votes – are investigated, with particular attention to its ability to protect minorities. The unique average voting outcome is characterized with a median formula which depends on the voters’ preferred...

A student’s future log-wage is given by the sum of a skill premium and a random personal “ability” term. Students observe only a private, noisy signal of their ability, and universities can condition admission decisions on the results of noisy tests. We assume first that universities are...

To analyze equality of opportunity we examine the influence of family characteristics on the distribution of outcome for a given generation. Here, we study changes in equality of opportunity for income acquisition between 1977 and 1993, conditional on father's income level and income rank, using...

We investigate the problem of how to make welfare comparisons of income distributions hen a population allocation problem (how a population should be optimally divided over families for given resources) adds to the usual income allocation problem. Pro-family and anti-family stances are...
