Economic research on migration tends to focus on workers, labour markets, or communities in receiving countries. However, labour migration and earnings could have important impacts on migrants’ home countries. This column explores these effects by focusing on circular migration from Malawi to South Africa in the 1960s and 1970s. Malawian districts that had the greatest exposure to migration shocks have better educated workers, even three decades later. These findings point to potential ‘brain gain’ effects for sending communities.

We traditionally think of migrants draining their home country of knowledge and skills, and, instead, giving their all to their host country. Based on patent and inventor data, this column looks at knowledge diffusion conveyed by highly skilled migrants both within their host country as well as back to their homelands. China, South Korea and Russia seem to profit from their diaspora’s knowledge generation but the same can’t be said for India.

Is the brain drain reversing? This column argues that increasing numbers of foreign-educated and economic emigrants are returning home. Evidence suggests that the best of the bunch bring with them strong corporate governance practises and an appetite for internationalisation. Through this ‘brain gain’, the return of skilled professionals boosts emerging markets’ economies.
