Growth and Inequality in the Dual Model of Development: The Role of Demand Factors
通过完整的一般均衡模型分析二元经济发展中的收入分配变化，利用洛伦兹曲线而非汇总指标，发现传统部门的需求弹性和价格弹性是影响不平等变化的关键，且二元阶段不平等明确下降的可能性不大。
This paper relates growth and income distribution in the development of a dual economy. Its originality lies in the fact that the analysis of income inequality uses the whole Lorenz curve instead of some summary measures, and that the dual economy is represented through a fully-specified general equilibrium model. Conditions for particular shifts in the Lorenz curve are derived. They mostly involve the income and price elasticities of demand faced by the traditional sector of the economy, and suggest that an unambiguous drop in income inequality is somewhat unlikely at the dual stage of development.
