Workers' Education, Spillovers, and Productivity: Evidence from Plant-Level Production Functions
利用企业-工人匹配数据估计生产函数，发现大学毕业生占比上升快的城市，工厂生产率提升更多，但被劳动力成本上升抵消；且经济距离近的行业间溢出效应更大。
I assess the magnitude of human capital spillovers by estimating production functions using a unique firm-worker matched data set. Productivity of plants in cities that experience large increases in the share of college graduates rises more than the productivity of similar plants in cities that experience small increases in the share of college graduates. These productivity gains are offset by increased labor costs. Using three alternative measures of economic distance—input-output flows, technological specialization, and patent citations—I find that within a city, spillovers between industries that are economically close are larger than spillovers between industries that are economically distant.
