Immigration and American Jobs

For years, economists have been poring through job market statistics looking for evidence that immigrants undercut less-educated Americans in the labor market. The most recent empirical studies conclude that the impact is slight: they confirm earlier findings that immigration on the whole has not led to fewer jobs for American workers. More significantly, they suggest that immigrants have had, at most, a small negative impact on the wages of Americans who compete with them most directly, those with a high school degree or less.

Meanwhile, the research has found that immigrants – including the poor, uneducated ones coming from south of the border — have a big positive impact on the economy over the long run, bolstering the profitability of American firms, reducing the prices of some products and services by providing employers with a new labor source and creating more opportunities for investment and jobs. Giovanni Peri, an economist at the University of California at Davis, estimated that the wave of immigrants that entered the United States from 1990 to 2007 increased national income per worker by about $5,400 a year on average, in 2007 dollars. He also concluded that the wave had a small positive impact on the average wage of American workers, by lifting the overall economy. If immigrants hurt anyone, it was the previous cohort of immigrants, with whom they most directly compete in the labor market.

These conclusions may seem to fly in the face of the laws of supply and demand. But they are not quite so odd. They can become obvious, in fact, once we take into account the response of American companies, and workers, to the inflows of cheap foreign labor.

The belief that immigration would simply displace American workers relies on the assumption that employers would do nothing but replace their costly domestic labor force with cheap imports. But that’s not typically what happens. For one thing, immigrants and domestic workers are not identical. Even the least-educated Americans are likely to be more fluent in English — better at talking with bosses or communicating with customers. When a contractor in Fresno expands into roofing, it will not just need a bunch of cheap immigrant roofers. It will also need an American supervisor and maybe an extra clerk.

Faced with a new, different pool of workers, companies often invest to reap the higher profits that the labor allows. Contractors, for instance, will be able to take on projects that would not have been profitable paying higher wages to domestic workers – like the roofing example in Fresno. This provides new opportunities for immigrants and for more highly paid domestic workers alike.

Mr. Peri and Chad Sparber of Colgate University found that American workers in states with large shares of less-educated immigrants gravitate toward occupations like cashiers and bank tellers, waiters or sales floor clerks, which require more communications skills. Foreigners, in turn, stick to manual tasks and physical labor. By encouraging this specialization and capital investment, immigration contributes to productivity growth.

In other words, immigration can produce domestic jobs. Restaurants are much less common in Norway than the United States because Norway lacks the cheap labor — making a dinner out in Oslo prohibitively expensive. In many New York restaurants, the American waiters and hosts owe their jobs to the underpaid illegal immigrants in the kitchen, whose low wages allow the restaurant to exist. The vast agricultural industry in the Central Valley of California might not exist without cheap immigrant farm workers who make it profitable.
