On a Distance Function-Based Inequality Measure in the Spirit of the Bonferroni and Gini Indices

Subramanian, S. - World Institute for Development Economic Research … - 2012

A natural way of viewing an inequality or a poverty measure is in terms of the vector distance between an actual (empirical) distribution of incomes and some appropriately normative distribution (reflecting a perfectly equal distribution of incomes, or a
