This paper explores the link between polarization and inequality and proposes some analytical methods to decompose the Duclos, Esteban, and Ray (2004) polarization index by population groups or income sources. In some cases, the decomposition methods were extend to the Esteban and Ray (1994)...

This paper studies the pro-poor growth in the Latino American Andean countries. We first present different definitions of pro-poorness and the related methods in order to generate the statistically robust results for classes of pro-poor measures. Also, we present the non anonymous pro-poor...

We propose a DSGE model with income heterogeneity to help discriminate across competing explanations of the cross-sectional divergence in debt-to-income ratios in US data. We show that for a DSGE model to be consistent with the data, the divergence in income growth should not be anticipated and...

The paper investigates how comparisons of multivariate inequality can be made robust to varying the intensity of focus on the share of the population that are more relatively deprived. It follows the dominance approach to making inequality comparisons, as developed for instance by Atkinson...

This paper develops the link between poverty and inequality by focussing on a class of poverty indices (some of them well-known) which aggregate normative concerns for absolute and relative deprivation. The indices are distinguished by a parameter value that captures the ethical sensitivity of...

Decomposing inequality indices across household groups or income sources is useful in estimating the contribution of each component to total inequality. This can help policy makers draw efficient policies to reduce disparities in the distribution of incomes using targeting tools. Decomposing...

Assessing the progressivity of a fiscal system is relevant to develop a global idea on the extent of redistribution. In this paper we assess the evolution of progressivity over time and how economic shocks and government fiscal policy affects its design. The social performance of fiscal...

The last 20 years have seen a significant evolution in the literature on horizontal inequity (HI) and have generated two major and "rival" methodological strands, namely, classical HI and reranking. We propose in this paper a class of ethically flexible tools that integrate these two strands....

This paper presents a computable general equilibrium model (CGEM) able to measure the impacts of the affirmative action policy set up in South Africa. In order to decrease inequalities inherited from the former regime, the government encourages firms to employ Historically Disadvantaged Persons...

In this paper we provide a set of rules that can be used to check poverty or inequality dominance using discrete data. Existing theoretical rules assumes continuity in incomes or in percentiles of population. In reality, with the form of household surveys, this continuity does not exist....
