Most welfare studies are based on the assumption that wellbeing is monotonically related to the variables used for the analysis. While this assumption can be regarded as reasonable for many dimensions of wellbeing like income, education, or empowerment, there are some cases where it is...

The paper deals with poverty orderings when the value of multidimensional attributes can be compared on a same scale, such as with income of different types or from different members of the same household. The dominance criteria extend the power of earlier multidimensional dominance tests (see...

Many authors have recently emphasized the crucial role of income inequalities in the design of efficient policies aimed at reducing poverty. However, the link between variations of the degree of inequality and variations of poverty are not well documented. The literature, for instance, does not...

This paper investigates the influence of invariance axioms in the decomposition of observed poverty variations into growth and inequality effects. After a complete and critical review of the invariance axioms suggested in the literature, we show that few information is needed for the ordering of...

Après des décennies de recherches intensives sur les distributions de revenus et malgré ses faiblesses empiriques, la loi log-normale jouit encore d'une popularité importante dans la littérature relative à la pauvreté et aux inégalités. La présente étude tente de mettre en évidence...

After decades of intensive research on the statistical size distribution of income and despite its empirical weaknesses, the lognormal distribution still enjoys an important popularity in the applied literature dedicated to poverty and inequality. In the present study, we emphasize the drawbacks...
