Assimilation and Changes in Cohort Quality Revisited: What Happened to Immigrant Earnings in the 1980s?
利用1970、1980和1990年美国人口普查数据，分析1980年代移民收入变化，发现新移民相对收入持续下降，且近期移民终生收入将比本地人低15%-20%。
"This article uses the 1970, 1980, and 1990 Public Use Samples of the U.S. census to document what happened to immigrant earnings in the 1980s and to determine if pre-1980 immigrant flows reached earnings parity with natives. The relative entry wage of successive immigrant cohorts declined by 9% in the 1970s and by an additional 6% in the 1980s. Although the relative wage of immigrants grows by 10% during the first 2 decades after arrival, recent immigrants will earn 15%-20% less than natives throughout much of their working lives."
