How General Is Human Capital? A Task‐Based Approach
提出任务特定人力资本概念，利用职业任务数据衡量技能跨职业的可转移性，发现劳动力市场技能比以往认为的更通用，且任务特定人力资本解释了高达52%的工资增长。
This article studies how portable skills accumulated in the labor market are. Using rich data on tasks performed in occupations, we propose the concept of task-specific human capital to measure empirically the transferability of skills across occupations. Our results on occupational mobility and wages show that labor market skills are more portable than previously considered. We find that individuals move to occupations with similar task requirements and that the distance of moves declines with experience. We also show that task-specific human capital is an important source of individual wage growth, accounting for up to 52% of overall wage growth. (c) 2010 by The University of Chicago.
