This paper proposes a microeconomic decomposition of the evolution of income inequality in Côte d’Ivoire in the 1990s, allowing the in-depth analysis of simultaneous contributions of four types of phenomena to the evolution of the distribution of income:a change in the remuneration rates of...

This paper studies the impact of the progressivity of income and inheritance tax on wealth inequality in France. By switching to a proportional tax system for each type of tax, we find that income-tax progressivity is more effective than inheritance-tax progressivity in reducing wealth...

For any TU game and any ranking of players, the set of all preimputations compatible with the ranking, equipped with the Lorenz order, is a bounded join semi-lattice. Furthermore, the set admits as sublattice the S-Lorenz core intersected with the region compatible with the ranking. This result...

French retirees benefit from specific taxation decreases. These tax exemptions imply considerable public tax expenditures that may be unjustifiable in terms of equity. In this article, we examine the adequacy of tax arrangements for French retirees in the current context of public pension...

In this paper, we apply a multidimensional decomposition of the Gini index to the active and retired populations in France. The multi-decomposition of an inequality measure allows us to put into perspective the role of social spending and taxation in reducing inequalities simultaneously among...

Despite the increasing awareness concerning the importance of distinguishing chronic and transient poverty for policy making, cross-country comparative studies of poverty dynamics in developing countries are virtually non-existent. The small, though increasing, number of existing studies makes...

This paper is dedicated to a theoretical and empirical survey of the relationship between trade, growth, poverty and inequality in developing countries. This relationship has been widely discussed by economists during the last few years. The first part presents the main stylised facts concerning...

How has poverty changed during the 1997-99 period, when the Peruvian economic performance deteriorated seriously under the negative impact of the international financial crisis? The answer to this question has traditionally relied on cross-section comparisons of poverty indicators. In this paper...

This paper examines for the first time inequality of opportunity for income in Africa, by analyzing large-sample surveys, all providing information on individuals' parental background, in five comparable Sub-Saharan countries: Ivory Coast, Ghana, Guinea, Madagascar and Uganda. We compute...
