A general class of progressivity indices is proposed which is consistent with the well-developed theory of the measurement of inequality and social welfare. In particular, we show that the more progressive a tax system, the more equal the distribution of net income and the greater the...

The paper simulates the redistributive impact of three possible scenarios for the introduction of a basic income (BI, also sometimes called "citizens' income") in Québec. The simulations are revenue neutral at the joint provincial-federal government level. The first scenario assumes that a set...

Is horizontal equity (HE) the "most widely accepted principle of equity"? Or does it stand in "opposition to the advancement of human welfare"? This paper argues that the case for the HE principle is not as straightforward as is usually thought and that it requires advanced notions of justice...

La littérature montre que la mesure des inégalités de revenu n’est pas suffisante pour appréhender les déterminants des inégalités. Les sources de rémunération, leurs corrélations au revenu global, leurs parts dans le revenu global, rentrent en compte dans la décomposition de la...

We propose simple graphical methods to identify poverty-reducing marginal reforms of transfer programs. The methods are based on Program Dominance curves that display cumulative program benefits weighted by powers of poverty gaps. These curves can be decomposed simply as sums of targeting...

This paper introduces the concept of Pigou-Dalton transfers between populations of income receivers. Gini's mean difference and Dagum's Gini index between populations are axiomatically derived in order to gauge the impact of within- and between-group Pigou-Dalton transfers on Dagum's measure. We...

Nous proposons une nouvelle méthode de décomposition. La multidécomposition de l’indicateur de Gini combine deux méthodes de décomposition : la décomposition en sous-groupes et la décomposition en sources de revenu. La technique retenue est mise en oeuvre dans le cadre d’une étude...

It is common to argue that poverty is a multidimensional issue. Yet few studies have included the various dimensions of deprivation to yield a broader and fuller picture of poverty. The present paper considers the multidimensional aspects of deprivation by specifying a poverty line for each...

The paper contributes to the measurement of poverty and vulnerability in three ways. First, we propose a new approach to separating poverty into chronic and transient components. Second, we provide corrections for the statistical biases introduced when using a small number of periods to estimate...
