Spatial skill concentration agglomeration economies
利用巴西人口普查和行政面板数据，研究发现分析性技能的空间集中对当地劳动力市场中所有工人的工资产生正向外部性，且独立于经典的市场规模效应。
Abstract Using the Brazilian census and administrative panel data, the present paper provides evidence that the spatial concentration of analytical skills generates positive wage externalities for all workers in the local labor market. We rely on shift‐share instrumental variables to overcome the endogeneity of skill concentrations. The observed externality is independent from the classical market size economies. The estimates are robust to geography, institutions and workers' sorting on unobservable abilities.
