Intergenerational income-group mobility and differential fertility.
分析发展中国家引入计划生育项目降低贫困人口生育率如何影响社会收入分配，通过稳态收入分布的不平等度量比较，为这类项目提供理论支持。
One question development economists are especially interested in but so far left unanswered is: how would the societal income distribution be affected by introducing a family-planning program to reduce the reproduction rate of the poor which is usually high in developing countries? The purpose of this paper is to search for analytical answers to this question. We are able to make definite comparisons about some class of inequality measures of the steady-state societal income distributions and these comparisons provide strong theoretical support in favor of the above-mentioned family-planning program.
