A common language facilitates communication
and economic efficiency, but linguistic diversity has economic and cultural
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.
Immigration crowds native workers out of risky
jobs and into less strenuous work, with consequent benefits to their
Public debate on immigration focuses on its
effects on wages and employment, yet the discussion typically fails to
consider the effects of immigration on working conditions that affect
workers’ health. There is growing evidence that immigrants are more likely
than natives to work in risky jobs. Recent studies show that as immigration
rises, native workers are able to work in less demanding jobs. Such market
adjustments lead to a reduction in native occupational risk and thus an
improvement in native health.
Economic integration of refugees into their host
country is important and benefits both parties
Refugee migration has increased considerably
since the Second World War, and amounts to more than 50 million refugees.
Only a minority of these refugees seek asylum, and even fewer resettle in
developed countries. At the same time, politicians, the media, and the
public are worried about a lack of economic integration. Refugees start at a
lower employment and income level, but subsequently “catch up” to the level
of family unification migrants. However, both refugees and family migrants
do not “catch up” to the economic integration levels of labor migrants. A
faster integration process would significantly benefit refugees and their
new host countries.
Benefiting from highly skilled immigrants
requires a complementary mix of immigrant selection and economic integration
There is increasing global competition for
high-skilled immigrants, as countries intensify efforts to attract a larger
share of the world's talent pool. In this environment, high-skill immigrants
are becoming increasingly selective in their choices between alternative
destinations. Studies for major immigrant-receiving countries that provide
evidence on the comparative economic performance of immigrant classes
(skill-, kinship-, and humanitarian-based) show that skill-based immigrants
perform better in the labor market. However, there are serious challenges to
their economic integration, which highlights a need for complementary
immigration and integration policies.
Business ownership is higher among immigrants,
but promoting self-employment is unlikely to improve outcomes for the less
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.
Reliable estimates of taxpayer effects are
essential for complete economic analyses of the costs and benefits of
Taxpayer effects are a central part of the
total economic costs and benefits of immigration, but they have not received
much study. These effects are the additional or lower taxes paid by
native-born households due to the difference between tax revenues paid and
benefits received by immigrant households. The effects vary considerably by
immigrant attributes and level of government involvement, with costs usually
diminishing greatly over the long term as immigrants integrate fully into
Understanding how migration responds to tax
changes will aid in setting the progressivity of a tax system
Decreased transportation costs have led to the
transmission of ideas and values across national borders that has helped
reduce the barriers to international labor mobility. In this context,
high-skilled individuals are more likely to vote with their feet in response
to high income taxes. It is thus important to examine the magnitude of
tax-driven migration responses in developed countries as well as the
possible consequences of income tax competition between nation states. More
specifically, how does the potential threat of migration affect a country’s
optimal income tax policies?
Migrants can have positive political effects on their home
The number of immigrants from developing countries living
in richer, more developed countries has increased substantially during the last decades.
At the same time, the quality of institutions in developing countries has also improved.
The data thus suggest a close positive correlation between average emigration rates and
institutional quality. Recent empirical literature investigates whether international
migration can be an important factor for institutional development. Overall, the
findings indicate that emigration to institutionally developed countries induces a
positive effect on home-country institutions.
Immigration may boost foreign direct investment,
productivity, and housing investment
Migration policies need to consider how immigration
affects investment behavior and productivity, and how these effects vary with the type
of migration. College-educated immigrants may do more to stimulate foreign direct
investment and research and development than low-skilled immigrants, and productivity
effects would be expected to be highest for immigrants in scientific and engineering
fields. By raising the demand for housing, immigration also spurs residential
investment. However, residential investment is unlikely to expand enough to prevent
housing costs from rising, which has implications for income distribution in
Immigrants’ retirement decisions can greatly
affect health care and social protection costs
As migration rates increase across the world,
the choice of whether to retire in the host or home country is becoming a
key decision for up to 15% of the world’s population, and this proportion is
growing rapidly. Large waves of immigrants who re-settled in the second half
of the 20th century are now beginning to retire. Although immigrants’
location choice at retirement is an area that has barely been studied, this
decision has crucial implications for health care and social protection
expenditures, both in host and origin countries.
