Capital–Skill Complementarity: Does Capital Composition Matter?
研究了资本构成如何影响资本与技能之间的互补性以及技能工资溢价，发现技术含量越高的资本与高技能劳动的互补性越强，且用技术资本替代非技术资本可能使技能工资溢价上升约9%。
Abstract We estimate the effect of capital composition on the size of capital–skill complementarity and the skill wage premium. Disaggregating the capital stock into different types according to technological content, we find that: capital is more of a q‐complement to skilled labor than to unskilled labor; the higher the technological component of capital, the larger the size of the relative q‐complementarity between capital and skilled labor; and replacing non‐technological with technological capital might increase the skill wage premium by about 9 percent. Our results highlight that changes in capital composition matter for understanding changes in the skill wage premium.
