A Theory of on-the-Job Learning
假设初级员工向资深员工在职学习，收入等于边际产值减去学费加上教学奖励，模型解释了经验收入曲线随就业增长率下降、大群体新员工收入偏高以及年龄收入曲线先增后凹并在退休前下降的现象。
In this paper, the author assumes that a junior worker learns on the job from senior workers. The worker's earnings are equal to his value of marginal product minus the tuition to his senior workers plus the teaching reward from his junior workers. The slope of the experience-earnings profile decreases with the employment growth rate. The earnings of an inexperienced worker of an unusually large cohort tend to be higher than the normal level. Finally, the author shows that his model generates an age-earnings profile which is increasing, concave in age, and declining near to retirement.
