Localized knowledge spillovers and skill‐biased performance
研究了本地化知识溢出对不同技能劳动者生产率差距的影响，发现溢出更有利于高技能者，并削弱了技能间的互补性，对城市政策制定者和企业管理者有参考价值。
Abstract This article focuses on a relatively unappreciated consequence of localized knowledge spillovers: their implications for productivity across skills. Spillovers benefit skilled workers more than unskilled ones, weaken complementarity between them, and widen their productivity gap. To test this theory, the authors use data from 146 U.S. cities and find that cities with a greater intensity of localized knowledge spillovers exhibit a bigger productivity gap across skills, after controlling for the endogeneity of knowledge spillovers, interindustry differences, and other factors. These results imply that in the long run, economies characterized by localized knowledge spillovers encourage investments in education and attract skilled people, raising the relative share of the skilled population. When complementarity across skills weakens, this analysis also offers a framework to link localized knowledge spillovers to the formation of entrepreneurial skill‐intensive firms.
