This paper studies the impact of immigration on native labor market outcomes in South Korea. We exploit the variation in immigration flows in an education-experience cell and find that, on average, immigration has no harmful effect on the wages or employment of native workers. However, there is a great heterogeneity of wage effects across education groups: high school dropouts suffer from the adverse effects, whereas the effects for college graduates are positive. We find the potential explanation for these differential effects in the suggestive evidence on the degree of substitution. Specifically, we examine the similarity of occupational distribution between natives and immigrants and assimilation patterns for immigrants.

本文研究了移民对韩国本地劳动力市场结果的影响。我们利用教育体验单元中移民流量的变化，发现平均而言，移民对本地工人的工资或就业没有有害影响。然而，不同教育群体的工资影响存在很大的异质性：高中辍学受到不利影响，而大学毕业生受到积极影响。我们在有关替代程度的暗示性证据中找到了对这些差异效应的潜在解释。具体来说，我们研究了本地人和移民之间职业分布的相似性以及移民的同化模式。
