2、ngineers, and maybe even create the next Google. Better yet, this plan wont cost the government a dime. In fact, it will save a lot of money. But few politicians are going to want to touch it.Heres the plan. more immigration. A pathway to legal status for undocumented immigrants. And a recognition t
3、hat immigration policy is economic policy, and needs to be thought of as such.See what I meant about politicians not liking it?Economists will tell you that immigrants raise wages for the average native-born worker. Theyll tell you that they make things cheaper for us to buy here, and that if we did
4、nt have immigrants for some of these jobs, the jobs would move to other countries. Theyll tell you that we should allow for much more highly skilled immigration, because thats about as close to a free lunch as youre likely to find. Theyll tell you that the people who should most want a path to legal
5、 status for undocumented immigrants are the low-income workers who are most opposed to such plans. And about all this, the economists are right.There are also noneconomic considerations, of course. Integrating cultures and nationalities is difficult. Undocumented immigrants raise issues of law and f
6、airness. Border security is important. Those questions are important. Theyre just not the subject of this column.The mistake we make when thinking about the effect immigrants have on our wages, says Giovanni Peri, an economist at the University of California, Davis, who has studied the issue extensi
7、vely, is we imagine an economy in which the number of jobs is fixed. Then, if one immigrant comes in, he takes one of those jobs or forces a worker to accept a lower wage. But thats not how our economy works.With more laborparticularly more labor of different kindsthe economy grows larger. It produc
8、es more stuff. There are more workers buying things, and that increases the total number of jobs. We understand perfectly well that Europe is in trouble because its low birthrates mean fewer workers, and that means less economic growth. We ourselves worry that were not graduating enough scientists a
9、nd engineers. But the economy doesnt care if it gets workers through birthrates or green cards.In fact, theres a sense in which green cards are superior. Economists separate new workers into two categories: those who “substitute“ for existing labor (were both construction workers, and the boss can e
10、asily trade you out for me) and those who “complement“ existing labor (youre a construction engineer and Im a construction worker). Immigrants, more than U. S.-born workers, tend to be in the second category, as the jobs you want to give to someone who doesnt speak English very well and doesnt have
11、many skills are different from the jobs you give to people who are fluent and have more skills.That means firms can expand more rapidly because they have more labor of different types, and that native workers can do jobs where theyre more productive. If you have lots of immigrant laborers willing to
12、 build things, a firm can build more things (and build them in America), and has more need for native workers who can supervise the production and do the technical work. The effect of all thiswhich has been demonstrated in multiple studiesis that immigrants raise wages for the average American.But t
13、hats only half of their benefit. “Living standards are a function of two things,“ says Michael Greenstone, director of the Hamilton Project, which is hosting a Washington conference on the economics of immigration next week. “Theyre a function of our wages and the prices of the goods we purchase.“ A
14、nd immigrants reduce the prices of those goods. Patricia Cortes, an economist at the University of Chicagos Booth School of Business, found that immigrants lowered the prices in “immigrant-intensive industries“ like housekeeping and gardening by about 10 percent. So our wages go up and the prices of
15、 the things we want to buy go down.We should remember, though, that the average worker isnt every worker. A study by Harvard economists George Borjas and Lawrence Katz found that although immigrants raised native wages overall, they slightly hurt the 8 percent of workers without a high-school educat
16、ion and those with a college education. A subsequent study by Peri looked harder at the ways immigrant labor differed from native labor and found that all groups of workers saw a benefit from immigrantsthough unskilled workers saw less of a benefit than highly skilled workers.And unskilled workers f
17、ace even tougher competition from undocumented immigrants who, because their status is so fragile, will accept pay beneath the minimum wage. And they are unlikely to complain about safety regulations or work conditions. That takes unskilled immigrants from being a bit cheaper than unskilled natives
18、and makes them a lot cheaperwhich makes employers likelier to hire them for jobs that native workers could do better.This suggests, first, that American workers would be better off if we figured out a way to take the 12 million undocumented immigrants and give them legal status, and second, that we
19、might want to give them more direct help if were going to increase immigration. Both are possiblejust politically difficult.What shouldnt be politically difficult is forming a consensus around increasing the number of highly skilled immigrants. Due to a 1965 law, our immigration system is based on f
20、amily unification. More than 65 percent of visas are for purposes of bringing family members to the United States. Only 15 percent are for economic reasons. As Darrell West of the Brookings Institution writes in his book Brain Gain, this means that immigrant families, rather than current policymaker
21、s, decide who enters the country.There are other benefits to higher immigration, too. Contrary to popular belief, immigrants tend to pay more money to the government than they get back from it, as they pay lots of taxes but often collect fewer benefits. Theyre young, which helps us keep our entitlem
22、ents afloat as the boomers retire.And then, of course, there are the benefits to the immigrants themselves and to their families back home.
