We show that it is possible to reconcile the utilitarian and welfarist principles under the requirement of unanimity provided that the set of profiles over which the consensus is attained is rich enough. More precisely, we identify a closedness condition which, if satisfied by a class of...

This paper shows that within-country happiness inequality has fallen in the majority of countries that have experienced positive income growth over the last forty years, in particular in developed countries. This new stylized fact comes as an addition to the Easterlin paradox, which states that...

Measuring individual preferences of savers have two main motivations: to reduce the share of non-observed heterogeneity in explaining households' wealth behaviors, and to construct more accurate tests of the theories of savings and portfolio choices. For France, we have constructed a unique data...

In spite of the great U-turn that saw income inequality rise in Western countries in the 1980s, happiness inequality has dropped in countries that have experienced income growth (but not in those that did not). Modern growth has reduced the share of both the "very unhappy" and the "perfectly...

Traditional indices of bi-dimensional inequality and polarization were developed for cardinal variables and cannot be used to quantify dispersion in ordinal measures of socioeconomic status and health. This paper develops two approaches to the measurement of inequality and bi-polarization using...

This article analyses the distributional impact of remittances across two regions of Algerian emigration (Nedroma and Idjeur) using an original survey we conducted of 1,200 households in 2011. Remittances and especially the role played by foreign pensions decrease the Gini index by nearly 4 %...

Using a capital-skill complementarity technology, we analytically show that an increase in the direct redistributivity of Pay-As-You-Go (PAYG) pension systems has a positive impact on wages and on wage inequalities. We also show that life expectancyinequalities play an important role in the...

In this paper we study the macroeconomic impact of a policy which changes the redistributive properties of an unfunded pension system. Using an overlapping generations model with a closed economy and heterogenous agents, we show that a weaker linkbetween contributions and benefits has an impact...

The paper explores different applications of the Shapley value for either inequality or poverty measures. We first investigate the problem of source decomposition of inequality measures, the so-called additive income sources inequality games, baed on the Shapley Value, introduced by Chantreuil...

Macroeconomic instability has been increasingly considered as a factor lowering average income growth and by this way is a factor slowing down poverty reduction. But it can also result in slower poverty reduction for a given average rate of growth, due to poverty traps, often examined at the...
