The Bonferroni Index of Income Inequality

Summary
This paper examines another old-new measure of income inequality: the Bonferroni index. Numerous definitions and interpretations are presented and discussed in the setting of several common models of income distribution. Various standard results are used to investigate the disaggregation of the index in terms of the factor components of total income as well as its decomposition by population subgroups and income classes..
