| Abstract: | This paper provides two extensions to the group decomposition of the Gini index by Yitzhaki and Lerman. First, within group, stratification, and between group inequality are analyzed along several dimensions at once. This provides for a better understanding of the determinants of inequality. Second, the impact on the Gini of marginal changes in income or consumption by group is derived. This can be used to evaluate targeted redistributive policies or assess the impact of exogenous shocks by group. The analysis is applied to data from Bangladesh with a focus on the impact of land ownership, education, and occupation on inequality. |
