Academic breeding grounds: Home department conditions and early career performance of academic researchers
研究了博士培养期间所在研究组的特征（如博士生数量、资助方式）如何影响博士毕业生早期的学术产出和引用影响力，发现组内博士生过多会降低产出，而受资助方影响论文选题的博士生虽更可能留在学界，但产出和引用较低。
This study investigates how research group characteristics relate to the early career success of PhD candidates who are trained in the group. In particular, I study how the citation impact of early-career PhDs is related to the staff composition and funding of the group. Using data on a cohort of Swedish doctoral graduates in science, engineering, mathematics and medicine, two sets of findings are obtained. First, students who were trained in groups with a lower number of PhD students perform better in terms of academic productivity. From the perspective of research policy, this finding suggests a decreasing return to funding additional PhD student positions allocated to professors who are already maintaining larger research groups. Second, PhD students trained in groups with funding for PhD research that is conditioned by funder influence over the topic of thesis research are more likely to stay in academia. Controlling for career destination, however, PhDs from such groups have lower than average scientific productivity and citation impact. These results suggest that funders of PhD studies face a trade-off between the two different funding objectives of "getting what they want" in terms of research content and fostering successful scholars.
