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 proposes techniques to test whether growth has been pro-poor. We first review different definitions of pro-poorness and argue for the use of methods that can generate results that are robust over classes of pro-poor measures and ranges of poverty lines. We then provide statistical...

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...

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...

Qu'es-ce que la liberté? Qu'es-ce que l'égalité? En quoi une plus grande égalité peut-elle accroître la liberté? Telles sont les questions principales auxquelles tente de répondre cet article. Le problème du choix entre liberté et égalité soulève en effet le problème de la...

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....

The main aim of this paper is to explore the link between poverty and inequality. In developing countries, there is a general consensus that high inequality can dampen significantly the impact of economic performance on poverty. In this paper, we propose a new theoretical framework that links...

We propose a class of social evaluation functions and of inequality indices which merge the useful features of the family of Atkinson (1970) and of S-Gini (Donaldson and Weymark (1980, 1983), Yitzhaki (1983) and Kakwani (1980)) indices. These social evaluation functions can be interpreted as...

We first review different definitions of pro-poorness and argue for the use of methods that can generate results that are robust over classes of pro-poor measures and ranges of poverty lines.

We use spline interpolation to approximate the subjective cumulative distribution function of an economic agent over the future realization of a continuous (possibly censored) random variable. The method proposed exploits information collected using a small number of probability questions on...
