Learning Curves, Personal Characteristics, and Job Performance
利用海军预备役招聘人员数据，估计在职学习、经验和个人特征对工作绩效的影响，发现前两年学习效应显著，低薪级人员学习曲线更陡峭。
Data on Naval Reserve recruiters are used to estimate the effects of on-the-job learning, experience, and individual characteristics on job performance. Generalizations of the Poisson distribution form the basis for estimating the effects of explanatory variables and control for individual heterogeneity and overdispersion. The findings show strong learning effects during the first two years on the job. Furthermore, lower pay-grade individuals have steeper learning curves than individuals in higher pay grades. Estimates of individual differences in productivity show a large variance in unobserved ability. Copyright 1989 by University of Chicago Press.
