Extended Gini Indices of Inequality
提出了相对和绝对不平等基尼指数的推广,基于洛伦兹曲线和广义洛伦兹曲线,新指数能按严格凹的社会福利函数排序收入分布,而传统基尼指数不具备此性质。
This paper suggests generalizations of the Gini indices of relative and absolute inequality. The new families of indices are based respect ively on the Lorenz curve and the generalized Lorenz curve. Each inde x is shown to rank income profiles in a given simplex according to so me strictly-concave, social-evaluation function, a property which the Gini indices fail to satisfy.
