Migration affects a migrant’s home country in a variety of ways. In particular, shocks related to migration processes include changes in labour supply as well as changes in productivity. Migration processes also induce endogenous behavioural or policy responses as sending countries tend to adjust to ongoing shocks. Both shocks and responses affect labour resource availability and productivity.

Negative shocks in labour supply appear at early stages of migration, when a large number of people, mostly economic migrants, decide to leave their home country to seek employment and better living conditions elsewhere. These shocks may be positive at later stages of migration when return migration takes place and/or immigration may take over. Migration might even lead to depopulation or more often to massive departure of labour with specific levels and types of skills (e.g. nurses, doctors, teachers) which at least in the short-run may have severe adverse effects on the stock of human capital. In the medium run however, moderate emigration can result in improved incentives for skill accumulation and replenishment, thus enhancing productivity. These changes in labour supply, induced by migration, constitute the first channel through which migration affects development.
