Do Economists Swing for the Fences after Tenure?
研究1996-2014年间顶尖经济金融院系教师的数据，发现终身教职后论文数量和“本垒打”式高引论文比例在获得教职时达到峰值，随后十年持续下降，而低引论文数量则上升。
Using a sample of all academics who pass through top 50 economics and finance departments from 1996 through 2014, we study whether the granting of tenure leads faculty to pursue riskier ideas. We use the extreme tails of ex-post citations as our measure of risk and find that both the number of publications and the portion consisting of “home runs” peak at tenure and fall steadily for a decade thereafter. Similar patterns hold for faculty at elite (top 10) institutions and for faculty who take differing time to tenure. We find the opposite pattern among poorly cited publications: their numbers rise post-tenure.
