摘要

我们通过提供资本体现的技术变革(CETC)和职业层面资本与劳动力之间替代弹性的第一个度量，研究了不同职业之间暴露于因素偏倚技术变革的差异。我们在两种测量方法中都记录了相当大的职业异质性，但在数量上，是因素可替代性的异质性促使工人暴露于CETC。在一个工人跨职业分类的一般均衡模型中，CETC几乎解释了1984年至2015年间美国观察到的所有劳动力再分配。要素可替代性不存在职业异质性，CETC仅占17% (JEL I26, J16, J24, J31, O33)。

Occupational Exposure to Capital-Embodied Technical Change

We study differences in exposure to factor-biased technical change among occupations by providing the first measures of capital-embodied technical change (CETC) and of the elasticity of substitution between capital and labor at the occupational level. We document sizable occupational heterogeneity in both measures, but quantitatively, it is the heterogeneity in factor substitutability that fuels workers’ exposure to CETC. In a general equilibrium model of worker sorting across occupations, CETC accounts for almost all of the observed labor reallocation in the US between 1984 and 2015. Absent occupational heterogeneity in factor substitutability, CETC accounts for only 17 percent of it (JEL I26, J16, J24, J31, O33)
