The Functional Role of Inequality: Some Lessons from Development

9709254雷经济学中一个基本有趣的话题是资产和收入不平等的因果关系。这个项目在两个不同的市场：土地和劳动力的背景下研究不平等的演变及其对效率的影响。第一部分研究发展中国家土地产权与经济增长之间的因果关系。更具体地说，这项研究考察了土地保有权安排导致财富分配以扩大不平等而不是收敛为特征的条件。对土地保有权的分析通过研究土地销售市场来补充，土地销售市场会影响土地所有权随时间的分布。该项目考察了这个市场以一种导致土地持有量增加的方式运行的条件。该项目的第二部分研究了发展中国家劳动力市场的模型，在这些市场中，营养状况影响工作能力。?？

9709254 Ray A topic of fundamental interest in economics is the cause and effect of inequality in assets and incomes. This project studies the evolution of inequality and its effects on efficiency in the context of two different markets: land and labor. The first part studies the causal links between property rights for land and growth in developing countries. More specifically, the research examines conditions under which land tenure arrangements lead to wealth distributions characterized by widening inequality instead of convergence. The analysis of land tenure is supplemented by examining the market for land sales, which affects the distribution of landholdings over time. The project examines the conditions under which this market operates in a way that results in increased concentration of landholdings. The second part of the project studies models of developing country labor markets in which nutritional status affects work capacity. ??
