Immigration is a topic that raises many questions from both policymakers and the public, and researchers work to offer perspective. Some questions currently being posed are

  • Does immigration into the United States have a positive impact on native-born employment opportunities?
  • If remittance fees (that is, fees immigrants pay to send money home) are reduced, how much more money do migrants send home?
  • How does sponsorship of family members' immigration into the United States change immigration patterns?

Researchers discussed these questions and more at the Federal Reserve Bank of Atlanta's Americas Center research conference on Remittances and Immigration, held Nov. 5–6, 2010.

Unskilled immigrant labor and offshoring
Some highlights from the research presented at the conference include a paper by University of California, Davis professor Giovanni Peri that was recently profiled in the New York Times. Peri argues that unskilled immigrant labor helps prevent U.S. firms from relocating offshore.

The paper cites evidence indicating that less-educated immigrants are employed in jobs that require more manual and routine-intensive tasks and on average do not compete for jobs in which the bulk of native workers are employed. Those jobs tend to be more cognitive and nonroutine-intensive type of work. In other words, immigrants and low-skilled native workers are not substitutes but complements. In fact, unskilled immigrants compete more with offshore workers. The paper concludes that immigration generates cost-savings for U.S. firms and thus a corresponding increase in productivity, so immigration's aggregate effect on the level of low-skilled native employment in the United States is positive.

This finding is in contrast to research conducted by George Borjas of Harvard University, who also participated in the conference. His work suggests that rather than being complements, immigrants with similar skill levels tend to be substitutes for native workers.

Remittance fees
In 2008, immigrants sent $336 billion to their relatives in developing countries, and in many countries remittances are often greater than private capital flows and official development aid combined. Remittance flows also generate billions of dollars in fees.

Dean Yang, from the University of Michigan, quantifies the impact of money transfer fees on remittances flows. Using a unique field experiment among Salvadoran migrants in the Washington, D.C., area, migrants were randomly assigned discounts on remittance transactions fees. Surprisingly, minor reductions in remittance fees led to large increases in total transfers. For instance, a $1 reduction in transaction costs generated $25 more remitted dollars per person per month. This finding suggests that a reduction in transaction costs can lead to very sizable gains in recipient countries.

Sponsorship of family members
Although countries such as Canada and Australia prioritize the entry of young, skilled foreign workers, the U.S. immigration system strongly emphasizes family reunification, which is a method where naturalized immigrants can sponsor relatives (spouse, children, parents, and siblings) in their immigration to the United States. Sponsoring new immigrants means that migrants not only are a major source of remittances, but they can fundamentally shape the flow of immigration by assisting migration of their relatives.

Until now, researchers had limited data on sponsors' behavior. Using a new immigration survey, Yale University professor Mark Rosenzweig presented research that for the first time explores the role of sponsorship. He shared preliminary results showing that while immigrant children who are less educated tend to receive remittances from their relatives who have immigrated to the United States, children with more schooling are able to take better advantage of the U.S. job market and are the first ones to be sponsored.

Other papers included research aimed at quantifying the effect of female migration on children left behind, the impact of immigrants on the educational attainment on natives, the productivity gains from skilled migration into the United States, and the role of seasonal migration in mitigating famine in Bangladesh. All of the conference papers are available.
