Does Employer Learning Vary by Occupation?
研究了雇主对工人能力的了解是否因职业不同而有差异，发现职业显著影响学习过程，且独立于教育水平。
Models of employer learning have two implications: first, the distribution of wages becomes more dispersed as a cohort of workers gains experience; second, the coefficient on an ability correlate that employers initially do not observe grows with experience. If learning by employers varies across occupations, both of these indicators of learning should covary positively across groups defined by a worker's initial occupational assignment. This paper tests these implications using data from the NLSY79 and CPS. I find that there is significant heterogeneity in the employer learning process across occupations and that occupational assignment affects the learning process independently of education.
