Migration and ethnicity

Evidence suggests that immigrants face an initial decline in their occupational status when they enter the host country labor market but that their position improves as they acquire more country-specific human, cultural, and occupational capital. High-skilled immigrants from countries that are economically, linguistically, and culturally different from the host country experience the greatest decline and the steepest subsequent increase in their occupational status. In the context of sharp international competition to attract high-skilled immigrants, this adjustment pattern is contradictory and discourages potential high-skilled migrants.

In the popular immigration narrative, migrants leave one country and establish themselves permanently in another, creating a “brain drain” in the sending country. In reality, migration is typically temporary: Workers migrate, find employment, and then return home or move on, often multiple times. Sending countries benefit from remittances while workers are abroad and from enhanced human capital when they return, while receiving countries fill labor shortages. Policies impeding circular migration can be costly to both sending and receiving countries.

In today's globalized world, people are increasingly mobile and often need to communicate across different languages. Learning a new language is an investment in human capital. Migrants must learn the language of their destination country, but even non-migrants must often learn other languages if their work involves communicating with foreigners. Economic studies have shown that fluency in a dominant language is important to economic success and increases economic efficiency. However, maintaining linguistic diversity also has value since language is also an expression of people's culture.

According to economic theory, a minimum wage reduces the number of low-wage jobs and increases the number of available workers, allowing greater hiring selectivity. More competition for a smaller number of low-wage jobs will disadvantage immigrants if employers perceive them as less skilled than native-born workers—and vice versa. Studies indicate that a higher minimum wage does not hurt immigrants, but there is no consensus on whether immigrants benefit at the expense of natives. Studies also reach disparate conclusions on whether higher minimum wages attract or repel immigrants.

Many immigrant destination countries face considerable pressure to change their immigration policies. One of the most innovative policies is auctioning the right to immigrate or to hire a foreign worker to the highest bidders. Visa auctions would be more efficient than current ways of allocating visas, could boost the economic contribution of immigration to the destination country, and would increase government revenues. However, visa auctions might weaken the importance of family ties in the migration process and create concerns about fairness and accessibility. No country has yet auctioned visas, although several have considered doing so.

The recent EU enlargements into Central and Eastern Europe and increased labor mobility within the Union provide a unique opportunity to evaluate the labor market effects of emigration. Outmigration has contributed to higher wages for stayers, as well as to lower unemployment in the source country. However, emigration has also exacerbated skills shortages in some sectors, as well as mismatches between skills and jobs.

Population aging will continue in the future, in both developed and developing countries. This may lead to lower migration, since the desire to migrate declines later in the life cycle. In addition, indirect labor demand effects may also reduce migration. However, migration of the elderly, return retirement migration, as well as mobility of certain specialist workers such as health and longer-term care providers, may increase. Also, in a family context, the emigration of children may have significant consequences for the elderly left behind, both in terms of poverty risk and health care.

The number of refugees has increased worldwide, and about half of them are children and youth. These refugee children arrive in resettlement countries with a unique set of challenges caused by, for instance, extreme stress and trauma that call for specific policies to address their needs. Yet, the long-term effect of refugee status on newcomer children's economic trajectories varies by country of origin, signaling the need for effective resettlement support and initiatives to tackle broader systemic barriers for newcomer children, beyond refugees. Such findings challenge the commonly held notion of refugees as a distinctive, relatively homogeneous group with similar trajectories.

Over recent decades, Western countries have admitted many immigrants from non-traditional regions (e.g. Philippines, India, China), which has coincided with poor economic integration. Language proficiency is an important determinant of economic integration; in addition to being a component of human capital, it plays a key role in facilitating the transmission of other components of human capital. Examining the strengths and weaknesses of objective and subjective measures of language proficiency is crucial for good integration policy, as is understanding the relationship between these measures and earnings, a key indicator of economic integration.

Immigrants are widely perceived to be highly entrepreneurial, contributing to economic growth and innovation, and self-employment is often viewed as a means of enhancing labor market integration and success among immigrants. Accordingly, many countries have established special visas and entry requirements to attract immigrant entrepreneurs. Research supports some of these stances, but expectations may be too high. There is no strong evidence that self-employment is an effective tool of upward economic mobility among low-skilled immigrants. More broadly prioritizing high-skilled immigrants may prove to be more successful than focusing on entrepreneurship.
