Black Immigrants in the United States: A Comparison with Native Blacks and Other Immigrants
利用1980年人口普查数据，比较了美国黑人移民与本土黑人在就业和工资上的差异，发现移民的就业优势源于迁移的选择性而非文化传统，且黑人移民的同化模式与白人移民不同。
Immigrant blacks have largely been ignored, both in discussions about racial discrimination and about the of immigrants. In analyzing immigrant blacks, Sowell (1978) claims to have evidence that it is not discrimination that is responsible for the poor labor market success of native blacks, but rather their traditions. Using the 1980 Census, I find that while immigrant blacks are more likely to be employed, their wages are not different conditional on employment. To the extent that there are differences, further investigation reveals that it is the selection processes associated with migration, and not cultural traditions which account for the differences between natives and immigrants. Finally, I find that black immigrants do not have similar assimilation patterns to white immigrants, and there is evidence that there has been a recent decline in the quality of the immigrant cohorts.
