Self-Selection and International Migration: New Evidence from Mexico
利用包含永久移民、回流移民和移民家庭的丰富迁移前数据，研究了墨西哥赴美移民的选择性，发现移民在收入上呈负向选择，主要源于美墨劳动力市场技能回报差异。
Abstract This paper examines the selection of Mexican migrants to the United States using novel data with rich premigration characteristics that include permanent migrants, return migrants, and migrating households. Results indicate that Mexican migrants are more likely to be young, male, and from rural areas compared to nonmigrants, but they are similar to nonmigrants in cognitive ability and health. Migrants are selected from the middle of the education distribution. Male Mexican migrants are negatively selected on earnings, and this result is largely explained by differential returns to labor market skill between the United States and Mexico rather than proxies for differential costs of migration.
