The Determinants and Welfare Implications of US Workers' Diverging Location Choices by Skill: 1980–2000
研究了1980-2000年间美国大学与高中毕业生工资差距扩大与地理分选加剧的现象，通过结构空间均衡模型发现本地劳动力需求变化是主因，而高技能城市的内生便利设施进一步加剧了不平等。
From 1980 to 2000, the rise in the US college/high school graduate wage gap coincided with increased geographic sorting as college graduates concentrated in high wage, high rent cities. This paper estimates a structural spatial equilibrium model to determine causes and welfare consequences of this increased skill sorting. While local labor demand changes fundamentally caused the increased skill sorting, it was further fueled by endogenous increases in amenities within higher skill cities. Changes in cities' wages, rents, and endogenous amenities increased inequality between high school and college graduates by more than suggested by the increase in the college wage gap alone.
