Matching, Heterogeneity and the Evolution of Income and Wage Inequality

本研究的第一部分将建立一个理论模型来检验工作不匹配、工资和收入不平等与经济增长之间的联系。由于寻找最佳工作的巨大成本和工人技能分散的增加，高技能雇员的物质资本（投资下）与人力资本的比例将低于低技能工人。当物质资本低于最优时，高技能工人的工资相对于低技能工人的工资将会下降，工资不平等将会减少，经济增长将会降低。该项目的第二部分着眼于公共教育和收入再分配对经济增长的影响。考虑到两国制度的差异，我们将对美国和英国进行实证比较。

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.
