Earnings of Hispanic Men: The Role of English Language Proficiency
利用1975年收入数据，研究英语熟练程度对西班牙裔男性融入美国劳动力市场的影响，发现英语技能差异几乎解释了通常归因于族裔、原籍国和在美国时间的全部工资差异。
The size and rapid growth of the Hispanic population in the United States raise many questions about the effects of language on the process of economic assimilation. This paper uses data on earnings for 1975 to explore the role of English language proficiency in the assimilation of Hispanic men into the U.S. labor market. The results are strong: differences associated with English language skills explain virtually all of the Hispanic wage differences usually attributed to ethnicity, national origin, and time in the United States. The analysis is completed by relating the measure of English language proficiency to assimilation-related variables.
