What is the impact of international migration on the origin country?

An important question about international migration is whether it affects the country of origin positively (“brain gain”) or negatively (“brain drain”). Below we have summarized the academic literature on this topic. At the top left, you can filter the papers based on whether they document a positive or a negative effect (or something in between).

We are grateful to Daniel Han for compiling this literature.
