In this paper, we propose an alternative methodology to capture the impact of the inequality factors on poverty by decomposing the traditional Foster-Greer-Thorbecke index. We introduce a frame of decomposition of the Gini coefficient, including the overlapping effects. Our method disentangles...

This chapter is concerned with issues arising from the construction of ethical measures of inequality and poverty. The recent literature on measurement of inequality and poverty emphasizes the close connection between social welfare functions and ethical indices of inequality and poverty. This...

We propose a new decomposition of the Gini coefficient inspired by the opportunity egalitarian paradigm. Under the assumption that income is function of circumstances out of individual control, effort and unobservable factors, we identify fair and unfair inequalities as components of the total...

This paper points to flaws in Gini decompositions by income sources and population subgroups and to common pitfalls in the interpretation of decomposition results, focusing on methods within the framework of Rao (1969). We argue that within this framework Gini elasticities may provide the only...
