February 2013Choice of Country by the Foreign Born for PhD and Postdoctoral Study: A Sixteen-Country Perspective
with Paula Stephan, Giuseppe Scellato: w18809
We analyze the decisions of foreign-born PhD and postdoctoral trainees to come to the United States vs. go to another country for training. Data are drawn from the GlobSci survey of scientists in sixteen countries working in four fields. We find that individuals come to the U.S. to train because of the prestige of its programs and/or career prospects. They are discouraged from training in the United States because of the perceived lifestyle. The availability of exchange programs elsewhere discourages coming for PhD study; the relative unattractiveness of fringe benefits discourages coming for postdoctoral study. Countries that have been nibbling at the U.S.-PhD and postdoc share are Australia, Germany, and Switzerland; France and Great Britain have gained appeal in attracting postdocs,...
December 2012Mobile Scientists and International Networks
with Giuseppe Scellato, Paula Stephan: w18613
This paper explores the link between mobility and the presence of international research networks. Data come from the GlobSci survey of authors of articles published in 2009 in four fields of science working in sixteen countries. Summary evidence suggests that migration plays an important role in the formation of international networks. Approximately 40 percent of the foreign-born researchers report having kept research links with colleagues in their country of origin. Non-mobile researchers are less likely to collaborate with someone outside their country than are either the foreign born or returnees. When the non-mobile collaborate, their networks span fewer countries. Econometric results are consistent with the hypothesis that internationally mobile researchers contribute significan...
November 2012The Mover's Advantage: Scientific Performance of Mobile Academics
with Giuseppe Scellato, Paula Stephan: w18577
We investigate performance differentials associated with mobility for research active scientists residing in a broad spectrum of countries and working in a broad spectrum of fields using data from the GlobSci survey. We distinguish between two categories of mobile scientists: (1) those studying or working in a country other than that of origin and (2) those who have returned to their native country after a spell of study or work abroad. We compare the performance of these mobile scientists to natives who have never experienced a spell of mobility and are studying or working in their country of origin. We find evidence that mobile scientists perform better than those who have not experienced mobility. Among the mobile, we find some evidence that those who return perform better than the ...
May 2012Foreign Born Scientists: Mobility Patterns for Sixteen Countries
with Giuseppe Scellato, Paula Stephan: w18067
We report results from the first systematic study of the mobility of scientists engaged in research in a large number of countries. Data were collected from 17,182 respondents using a web-based survey of corresponding authors in 16 countries in four fields during 2011. We find considerable variation across countries, both in terms of immigration and emigration patterns. Switzerland has the largest percent of immigrant scientists working in country (56.7); Canada, and Australia trail by nine or more percent; the U.S. and Sweden by approximately eighteen percent. India has the lowest (0.8), followed closely by Italy and Japan. The most likely reason to come to a country for postdoctoral study or work is professional. Our survey methodology also allows us to study emigration patterns of ...
