“…The phenomenon of brain drain at origins and brain gain at destinations is commonly found in the South-North migration of highly skilled personnel (Frédéric et al, 2007); in other words, developing countries are major places of origin for migrants, while developed countries represent major destinations (Gibson & McKenzie, 2011). Some studies have examined the migration of highly skilled personnel within nation-state borders, in countries such as the United States (Partridge et al, 2012), the United Kingdom (Faggian et al, 2007), Germany (Teichert et al, 2020), Russia (Aldieri et al, 2020), Australia (Corcoran et al, 2010) and China (Zhou et al, 2018). Most existing research on highly skilled international or domestic migrants focuses on returns to skills (Borjas et al, 1992;Zhao & Hu, 2019), economic impact (Nathan, 2013) and migration policies (Boucher, 2019); indeed, this type of migrant is largely perceived as an economic actor.…”
