摘要本文探讨了在国外出生的美国人的数据集中，位于美国以外是否会降低研究生产率。受过教育的科学家仪器位置与签证状态，需要返回本国，我们发现一个大的负相关关系非美国的位置和研究产出的人均收入低的国家，但没有人均收入高的国家。这表明，一个外来的科学家位于收入分配的顶端，可以期望在研究中像他或她在美国一样富有成效。
Abstract This paper asks whether being located outside the United States lowers research productivity in a data set of foreign-born, U.S.-educated scientists. Instrumenting location with visa status that requires return to home countries, we find a large negative relationship between non-U.S. location and research output for countries with low income per capita but none for countries with high income per capita. This suggests that a scientist exogenously located in a country at the top of the income distribution can expect to be as productive in research as he or she would be in the United States.
