Why do older scholars slow down?
利用1969至2018年五大经济学期刊数据，研究发现年长学者发表减少主要源于习惯性行为，而非领域差异；引用率高和顶级发表多的作者退休更晚。
Abstract Using data describing all “Top 5” economics journal publications from 1969 to 2018, we examine what determines which authors produce less as they age and which retire earlier. Sub‐field has no impact on the rate of production, but interacts with it to alter retirement probabilities. A positive, tentative, and contemporary writing style increases persistence in publishing. Authors whose previous work was more heavily cited produce slightly more. Those better‐cited with more top‐flight publications retire later than others. Declining publication with age arises mostly from habit—there is a very significant increasing positive autocorrelation of publication across the decades of a career.
