Are Immigrants the Most Skilled US Computer and Engineering Workers?
利用美国社区调查数据，研究移民计算机和工程工人的工资优势，发现移民的高学历带来工资优势，但英语不熟练会削弱其职业发展。
Using the American Community Surveys, I examine the wages of immigrant computer and engineering workers. Immigrants' higher education gives them a wage advantage over natives, an advantage larger for computer than for engineering workers, and larger in occupation-based samples than in education-based samples. Among holders of engineering degrees, immigrants earn less than natives, penalized by a high return to English proficiency. The results suggest that imperfect English may reduce their occupational advancement, or an unobserved factor may reduce both occupational advancement and the incentive to perfect English. In all samples, top immigrants from the highest-income countries far outearn top natives.
