This paper estimates the effect of obtaining US citizenship on individual-level measures of productivity for foreign-born doctoral recipients from US universities. Becoming a US citizen results in the removal of barriers such as access to public sector occupations and to some sources of government-sponsored research funding which are hypothesized to increase the productivity of foreign-born scientists. We utilize panel data from the Survey of Doctoral Recipients from 1993 to 2013 and individual fixed effects models to control for selection bias in the naturalization decision. Our results indicate that becoming a naturalized citizen increases wages and several measures of academic productivity. In support of our argument, we find that foreign-born workers who naturalize are more likely to utilize research funding from a government agency, but not more likely to work for the government post-naturalization.

外国出生博士学位的入籍和生产率

本文估算了获得美国国籍对美国大学外国出生的博士生个人生产率水平的影响。成为美国公民将消除障碍，例如获得公共部门职业和获得政府资助的研究经费的某些来源，这些障碍被认为可以提高外国出生的科学家的生产率。我们利用1993年至2013年的“博士接受者调查”的面板数据以及各个固定效应模型来控制入籍决策中的选择偏见。我们的结果表明，成为一名入籍公民可以提高工资，并提高学术生产率。为支持我们的论点，我们发现归化的外国出生的工人更有可能利用政府机构的研究经费，
