Quality of Education, Productivity Changes, and Income Distribution
构建了一个包含工人和管理者的双重经济一般均衡模型，将教育质量提升视为技术进步，分析不同生产率变化对工资和收入不平等的影响，发现教育质量下降通常加剧不平等，但某些群体可能以他人为代价受益。
A general equilibrium model of a dual economy is constructed with workers and managers and hierarchical production. Ability is continuous, and there is perfect competition in the product market. Higher quality of education is treated as a form of technical progress. An equilibrium wage profile is derived. Different kinds of technical and productivity changes yield different gainers and losers. Declines in the quality of education generally lead to an increase in inequality. Surprisingly, groups suffering from declines in quality of education often benefit at the costs of others. Parallels are drawn with recent experience. Copyright 2000 by University of Chicago Press.
