我们根据非法移民的预期终生收入考虑发达国家的两种可能的情况：高风险入境且在逗留期间被发现的风险较低（F 型移民）和低风险入境且高被发现的风险（S 型移民）。我们发现，如果中等生产力工人作为S类移民非法移民，如果生产力较低的工人作为F类移民非法移民，针对S类移民的内部调查政策将有助于提高非法移民的平均生产力。另一方面，如果中等生产力工人作为F类非法移民，而较低生产力工人作为S类非法移民，针对F类移民的边境管制政策将有助于提高非法移民的平均生产力。此外，我们发现，在本文研究的两个案例中，东道国扩大合法移民（高生产率非法移民合法化）减少了非法移民总数，并提高了总移民的平均生产率。
We consider two possible cases of illegal immigrants to a developed country based on their expected lifetime income: high-risk entrance with low risk of detection during their stay (type F migration) and low-risk entrance with high risk of detection (type S migration). We find that if medium productivity workers migrate illegally as type S immigrants, and if lower productivity workers migrate illegally as type F, internal investigation policies for type S immigrants will contribute to enhance the average productivity of illegal immigrants. On the other hand, if medium productivity workers migrate illegally as type F while lower productivity workers migrate illegally as type S, border control policies for type F immigrants will contribute to enhance the average productivity of illegal immigrants. Moreover, we find that the expansion of legal immigration (legalization of high productivity illegal immigrants) by the host country reduces the total number of illegal immigrants and enhances the average productivity of total immigrants in the two cases that were examined in this paper.
