Aging and Productivity Among Economists
研究发现，经济学家在职业生涯中，以顶级期刊发表量衡量的生产力随年龄增长显著下降，但论文接受率与年龄无关，且顶级作者的生产力下降速度并不比其他作者更快。
Economists'productivity over their careers and as measured by publication in leading journals declines very sharply with age. There is no difference by age in the probability that an article submitted to a leading journal will be accepted. Rates of declining productivity are no greater among the very top publishers than among others, and the probability of acceptance is increasingly related to the author's quality rather than the author's age. © 1998 by the President and Fellows of Harvard College and the Massachusetts Institute of Technology
