Immigrant Networks and Their Implications for Occupational Choice and Wages
利用美国人口普查数据，研究1980至2000年间美国区域劳动力市场中各族裔职业份额增长的原因，发现新移民倾向于选择同族裔已定居者的职业，且选择最普遍职业者获得更高工资。
Abstract Occupational shares of various ethnic groups have grew tremendously in regional U.S. labor markets from 1980 to 2000. Using U.S. Census data, we examine the extent to which this growth is attributed to network effects by studying the relationship between the occupational choice of recently arrived immigrants with those of established immigrants from the same country, We find strong evidence of network effects. First, new arrivals are choosing the same occupations as their compatriots, a decision that is operating at the regional level. Second, individuals who choose the most common occupation of their compatriots enjoy a large and positive earnings effect.
