An increase in the share of workers causes a mechanical increase of per-capita income but may affect it even further. Population growth through immigration can lead to additional increases in per-capita income in models where certain sectors of the economy become more efficient at higher production levels.
The researchers believe the late 19th and early 20th century immigrants stimulated growth because they were complementary to the needs of local economies at that time. Low-skilled newcomers were supplied labor for industrialization, and higher-skilled arrivals helped spur innovations in agriculture and manufacturing.
Unemployed workers are the group most likely to be affected by the presence of immigrants in their local labor markets, as they are actively competing for jobs. ... Fromentin (2012), using aggregated panel data for OECD countries, finds that immigration increases short- term unemployment but reduces long-term unemployment.

Cons of immigration
In 1917, the U.S. Congress enacted the first widely restrictive immigration law. The uncertainty generated over national security during World War I made it possible for Congress to pass this legislation, and it included several important provisions that paved the way for the 1924 Act.
Often stereotyped and discriminated against, many immigrants suffered verbal and physical abuse because they were "different." While large-scale immigration created many social tensions, it also produced a new vitality in the cities and states in which the immigrants settled.
The available evidence suggests that immigration leads to more innovation, a better educated workforce, greater occupational specialization, better matching of skills with jobs, and higher overall economic productivity. Immigration also has a net positive effect on combined federal, state, and local budgets.
Subsequent studies showed an insignificant rise in total unemployment as a result of long-term immigration. In addition, some studies have shown that immigration has a negative effect on unemployment, while it has a smaller or insignificant impact in regard to increases in short-term wages.
New research shows immigrants do not increase the unemployment rate of natives, nor do they lower the labor force participation rate of natives. ... “Instead, having more immigrants reduces the unemployment rate and raises the labor force participation rate of U.S. natives within the same sex and education group.”
A number of studies have examined whether immigration leads to higher unemployment or inactivity among existing workers, and most have found either small effects or no effect. ... First, that immigration has little or no impact on average employment or unemployment of existing workers.
