The study notes that when companies move production offshore, they pull away not only low-wage jobs but also many related jobs, which can include high-skilled managers, tech repairmen and others. But hiring immigrants even for low-wage jobs helps keep many kinds of jobs in the United States, the authors say. In fact, when immigration is rising as a share of employment in an economic sector, offshoring tends to be falling, and vice versa, the study found.
In other words, immigrants may be competing more with offshored workers than with other laborers in America.
American economic sectors with much exposure to immigration fared better in employment growth than more insulated sectors, even for low-skilled labor, the authors found. It’s hard to prove cause and effect in these studies, or to measure all relevant variables precisely, but at the very least, the evidence in this study doesn’t offer much support for the popular bias against immigration, and globalization more generally.
We see the job-creating benefits of trade and immigration every day, even if we don’t always recognize them. As other papers by Professor Peri have shown, low-skilled immigrants usually fill gaps in American labor markets and generally enhance domestic business prospects rather than destroy jobs; this occurs because of an important phenomenon, the presence of what are known as “complementary” workers, namely those who add value to the work of others. An immigrant will often take a job as a construction worker, a drywall installer or a taxi driver, for example, while a native-born worker may end up being promoted to supervisor. And as immigrants succeed here, they help the United States develop strong business and social networks with the rest of the world, making it easier for us to do business with India, Brazil and most other countries, again creating more jobs.
