SKILL, AGGLOMERATION, AND INEQUALITY IN THE SPATIAL ECONOMY
构建了一个包含技能异质性和集聚力的空间均衡模型，利用美国人口普查数据估计模型，发现技能构成和本地溢出分别解释城市层面生产率与就业关系的30%和70%，并分析了技能偏向性技术变化对福利不平等的影响。
Abstract This paper develops a spatial equilibrium model with skill heterogeneity and agglomeration forces that stem from local idea exchange. I structurally estimate the model using American census data to study policy effects on real wage inequality between and within college and noncollege workers. Using the estimated model, I find: (1) Skill composition and local spillovers, respectively, account for 30% and 70% of the city‐level relationship between productivity and employment. (2) Recent skill‐biased technological changes largely increased the welfare inequality between groups and within college workers. (3) Small transfers from larger to smaller cities may reduce inequality without changing aggregate welfare.
