A method to decompose the systemic risk in geographic areas

Abstract

In this paper, a method for evaluating systemic risk in different geographic areas is presented. The proposed methodology is based on the decomposition by subpopulations of the Gini index, largely used to assess the inequality of income and wealth. This decomposition procedure follows a two-step approach that goes beyond the “classical” decomposition Within and Between components, also allowing the assessment of the contribution to the total inequality for each subpopulation.
