Academic studies of negative effects of immigration

In “A Compendium of Recent Academic Work Showing Negative Impacts of Immigration,” the Center for Immigration Studies summarizes 32 research articles with address some negative effect of immigration.

I see two major features of this compendium. First, the most studied issue is a negative impact on native born persons with low formal education / low skills by immigration of people suitable for the same jobs.

Second, a key issue of immigration impact is completely missing: the impact of increased immigration on social and political tension. This issue has been acknowledged even by researchers who are pro-immigration, such as Robert Putnam (here).

Low skilled native born workers lose out: “This review paper is similar in content to the National Academies’ chapters, but it takes a more international perspective. After considering over 50 studies of immigration in developed countries, the author concludes that “immigration can create winners and losers among the native-born workers.” Because low-skill immigration tends to make low-skill natives the “losers” and high-skill natives the “winners”, rising inequality is a natural consequence.” (From here.) 

Restrictions lead to more mobility: “1920s immigration restrictions benefited rural Americans who migrated into cities to replace lost labor. In contrast, farmers mechanized rather than attempting to recruit new workers.” (From here.)

Farm mechanization: Some articles on the positive effect of reduced immigration on farm mechanization, and visa-versa. CIS addressed this in its own 2007 report, here.

Impact of refugee influx: “Resettling refugees may be a humanitarian good, but the argument that refugees are somehow an economic boon to their host nations is dubious. This paper reviews the evidence that refugees struggle to integrate into the economies of high-income host nations. In the U.S. specifically, refugees perform unusually well in finding jobs. However, in line with their counterparts in other rich nations, U.S. refugees earn low wages even after 10 years of residency. (From here.)
