This paper studies the relationship between immigration and crime by applying the Engelhardt et al. (2008) crime model. Although the relationship between immigration and crime has been widely debated, there is no theoretical explanation that can define the impact of immigration on crime. This model constructs two channels through which immigrants affect the host country's crime rate: composition (direct) channel and labor market (indirect) channel. These two channels provide explanations for the ambiguity of immigration effects on crime rates. An extension of the model with skill bias and imperfect substitution between skilled and unskilled labor has more sophisticated numerical results based on the United States (U.S.) labor market and immigration. A more generous unemployment insurance system for immigrants increases both the unemployment and crime rates. An extended period of incarceration and a deportation policy reduce crime rates but have no significant impact on labor market outcomes.

本文应用 Engelhardt 等人研究移民与犯罪之间的关系。(2008) 犯罪模型。尽管移民与犯罪之间的关系已被广泛讨论，但没有理论解释可以定义移民对犯罪的影响。该模型构建了移民影响东道国犯罪率的两个渠道：构成（直接）渠道和劳动力市场（间接）渠道。这两个渠道解释了移民对犯罪率影响的模糊性。基于美国（US）劳动力市场和移民的模型的扩展具有技能偏差和熟练和非熟练劳动力之间的不完全替代具有更复杂的数值结果。为移民提供更慷慨的失业保险制度会增加失业率和犯罪率。长期监禁和驱逐政策降低了犯罪率，但对劳动力市场结果没有显着影响。
