摘要:The share of foreign-born persons in the United States has increased rapidly over the last few decades, rising from 7.9 percent of the population in 1990 to almost 13.3 percent in 2014, representing about 41.3 million individuals—roughly 11.3 million of whom are estimated to be unauthorized immigrants (Passel and Cohn 2015). Most research on the economic impact of these trends focuses on the effects that immigration, particularly unauthorized/illegal immigration, has had on the job market prospects of native-born citizens, with the bulk of this research suggesting that immigration has had a minor but negative impact on wages and employment opportunities. 1 However, comparatively little is known about the effects of immigration on the labor market opportunities of the native-born unemployed in particular.
