Brain Drain & Brain Gain

_ImmigrantBusinessPeople

The movement of skilled workers internationally represents brain gain for the countries that reap their skills and experience and brain drain for their countries of origin. On the brain gain side of the divide, countries increasingly are looking to position their immigration policies to attract the types of international workers and students whose skills they desire. On the brain drain side, the development impacts of losing educated workers are being assessed in immigrant-sending and receiving countries alike as the research presented here shows.

Nigeria, Africa’s most populous country and one of its largest economies, sits at the crossroads of the continent’s migration landscape. As both a regional immigration hub and an origin for significant emigration, the country contends with a wide range of migration issues that have evolved over time. This country profile situates Nigeria's migration trends and policies.

Sahrawi children in the Smara Refugee Camp, in Algeria.

For five decades, Sahrawi refugees have been displaced from Western Sahara, which many people call "Africa’s last colony" and which the United Nations considers the world’s largest and most populous non-self-governing territory. As this article details, young Sahrawis have for decades left the isolated refugee camps to study and live abroad, but many seem increasingly inclined not to return.

People walk through the streets of Hong Kong

Hong Kong finds itself in the middle of opposing trends. Amid political unrest, Beijing's increasing security pressure, and pandemic disruptions, many Hong Kongers have left and been replaced by a new group of immigrants, largely from mainland China. The dynamic has raised questions whether Hong Kong will remain a global cosmopolitan hub or instead turn inward to Asia, as this article discusses.

A health worker from the Philippines.

Countries such as the United States, the United Kingdom, and Germany are increasingly relying on immigrant health-care workers to fill gaps in their workforce and care for aging populations. That has created opportunities for many foreign-born doctors and nurses, but could harm their origin countries. This article examines the dynamics of global health-care worker migration, particularly in the wake of the COVID-19 pandemic.

Protests at a refugee compound in Nauru.

For two decades, asylum seekers seeking to reach Australia by boat were diverted to Nauru, a small Pacific Island nation that made a hefty profit off the extraterritorial asylum arrangement. But attitudes among local Nauruans have been mixed, with some fearing their economy revolved around Australia and the foreign workers who shuttled in and out of the processing center. As more countries seek to strike offshore asylum deals, this article examines the effects on local communities.

This briefing in Bangkok launched an MPI-IOM Issue in Brief that reviews the impacts of the Philippines' successful labor export policy on skills development and human capital growth. While Filipino migrant workers contribute significantly to the national economy with the remittances they send home (more than USD 27 billion in 2014), this reliance on exporting labor raises an important question: Has the nation’s focus on preparing workers to leave compromised human capital development at home?

The time-critical work of cutting global emissions depends on countries’ ability to cultivate a workforce with the skills needed in sectors such as clean energy. Immigrants are already playing a role in this green transition.
