Matching, Heterogeneity and the Evolution of Income and Wage Inequality

达伦·阿西莫格鲁麻省理工学院SBR-9602116这项研究的第一部分将开发一个理论模型，考察工作错配、工资和收入不平等与增长之间的联系。由于寻找最佳工作的成本很高，工人技能的分散度增加，高技能员工的实物资本(投资不足)与人力资本的比率将低于低技能工人。在物质资本低于最优水平的情况下，高技能工人的工资将相对于低技能工人的工资下降，工资不平等将缩小，经济增长将会更低。该项目的第二部分着眼于公共教育和收入再分配对增长的影响。考虑到美国和英国在制度上的差异，我们将对这两个国家进行实证比较。

Daron Acemoglu Massachusetts Institute of Technology SBR-9602116 The first part of this research will develop a theoretical model examining the links job mismatch, wage and income inequality and growth. With significant costs of finding the best job and increases in the dispersion of worker skills, high skilled employees will have a lower ratio of physical capital (under investment) to human capital than low skilled workers. With less physical capital than optimal, wages of high skilled workers will decrease relative to wages of low skilled workers, wage inequality will be reduced and economic growth will be lower. The second part of the project looks at the effect of public education and redistribution of income on growth. An empirical comparison will be made between the U.S. and Great Britain, considering differences in institutions in the two countries.
