中文摘要

本文研究了孕期从发展中国家向发达国家的移民对子代结果的影响。我们利用1991年5月埃塞俄比亚犹太人移民以色列所产生的准实验变异,关注中期和长期结果。在移民前受孕的个体,根据其移民时的胎龄,在产前发育的不同阶段经历了环境条件的剧烈变化。我们发现,母亲在较早胎龄时移民的女性拥有更好的教育结果。她们成年后也倾向于工作更多。相比之下,我们在男性中未发现任何效应。

Abstract

Abstract This paper investigates the effects of immigration from a developing country to a developed country during pregnancy on offspring outcomes. We focus on intermediate- and long-term outcomes, using quasi-experimental variation created by the immigration of Ethiopian Jews to Israel in May 1991. Individuals conceived before immigration experienced dramatic changes in their environmental conditions at different stages of prenatal development depending on their gestational age at migration. We find that females whose mothers immigrated at an earlier gestational age have better educational outcomes. They also tend to work more as adults. In contrast, we do not find any effect among males.
