Careers in Firms: The Role of Learning about Ability and Human Capital Acquisition
利用一家企业的行政数据，估计了一个整合能力学习和人力资本获取的结构模型，发现能力学习通过改善工人与岗位的匹配间接影响工资增长和分化。
Job and wage mobility can arise from firms and workers learning about workers’ ability and from workers acquiring human capital with experience. To date, the relative importance of these two mechanisms is debated. Using administrative data from one firm, I estimate a structural model that integrates them. I find the direct effect of beliefs about ability on wages, which existing work has focused on, to be small. However, by improving the sorting of workers to the firm’s jobs, learning about ability is indirectly a crucial determinant of wage growth and dispersion.
