“…This choice of setting offers several advantages, the most salient of which are: large portability of skills, [3] a set of tasks clearly oriented to innovation, and relatively standard ways to measure output characteristics and performances. It is drawn on recent works which focus on scientific research as a setting for studying international mobility (Franzoni et al, 2014;Freeman and Huang, 2015;Ganguli, 2015;Slavova et al, 2016) as well as work that conceptualizes science in a knowledge recombination framework (Fleming and Sorenson, 2004;Wang et al, 2016). We use an original sample of 4336 surveyed scientists located in 16 countries conducting research in the four disciplines of biology, chemistry, earth and environmental sciences and materials science.…”
