Following Milanovic's (1997) paper [Economics Letters, vol. 56, p. 45-49], we propose a simple way to compute the Gini index when income y is a quadratic function of its rank among n individuals.

This study assesses the incidence of pollution control policies on households. In contrast to previous studies, we employ an integrated framework combining a multisector general equilibrium model with a stochastic dominance analysis using household-leved data. We consider three policy...

This article draws up a portrait of effective marginal tax rates (EMTRs) on labour income in Quebec. It aims at allowing a better understanding of the impact of tax policy on the behavior of economic agents. Using an accounting microsimulation model that reproduces the system of taxes and...

The paper proposes and applies statistical tests for poverty dominance that check for whether poverty comparisons can be made robustly over ranges of poverty lines and classes of poverty indices. This helps provide both normative and statistical confidence in establishing poverty rankings across...

Le financement public des services de garde (SDG) est au cœur d’objectifs multiples au Québec et ailleurs au Canada. Cet article rapporte l’impact des trois mesures principales de financement public (le crédit d’impôt provincial, la déduction d’impôt fédérale, et les subventions...

Income mobility is often thought to equalize permanent incomes and thereby to improve social welfare. The welfare analysis of mobility often fails, however, to account for the cost of the variability of periodic incomes around permanent incomes. This paper assesses the net welfare benefit of...

Four axioms are introduced in order to characterize the family of pair-based decomposable inequality measures, which is embraced in the class of weakly decomposable inequality measures. Three axioms, namely, normalization by pairs, aggregation by pairs, and decomposition by pairs enable the...

The evaluation of development processes and of public policies often involves comparisons of social states in which populations differ in size and longevity. This requires social evaluation principles to be sensitive to both the number and the length of lives. This paper explores the use of...

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...
