We investigate under which conditions it is possible to infer the evolution of poverty at the individual level from the knowledge of poverty among households. Poverty measurement is approached by the poverty orderings introduced by Foster and Shorrocks (1988). The analysis is based on a reduced...

Parmi les facteurs explicatifs proposés pour expliquer les inégalités sociales de santé, la littérature épidémiologique a récemment mis en avant l’influence du milieu social d’origine sur l’état de santé à l’âge adulte, cette influence résultant à la fois d’un effet...

This article analyses unequal opportunities for health related to original class and family background in Europe. The literature has recently highlighted the influence of original class background on health in adulthood and the existence of transmission between the generations. The data from the...

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...

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...

We study a simple model of assigning indivisible objects (e.g., houses, jobs, offices, etc.) to agents. Each agent receives at most one object and monetary compensations are not possible. We completely describe all rules satisfying efficiency and resource-monotonicity. The characterized rules...

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...

This article discusses the properties of Kolm’s ELIE proposal in the Context of optimal income taxation “à la Mirrlees”. It first shows that ELIE gives rise to non-standard type-dependent budget sets, which has important implications in terms of a minimum labour requirement. Second, it...

Simula and Trannoy (2007) have shown that ELIE is confronted with implementation issues when the policymaker cannot observe the time worked by every individual. This paper tries to fix this problem. To this aim, it characterizes the second-best allocations which are the closest to ELIE (i) in...

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...
