Citizenship, Fertility, and Parental Investments
研究德国2000年引入出生地公民权后，临时移民的生育决策如何响应，发现该政策降低了移民生育率，并改善了受影响儿童的健康和社会情感结果。
Citizenship rights are associated with better economic opportunities for immigrants. This paper studies how in a country with a large fraction of temporary migrants the fertility decisions of foreign citizens respond to a change in the rules that regulate child legal status at birth. The introduction of birthright citizenship in Germany in 2000, represented a positive shock to the returns to investment in child human capital. Consistent with Becker's “quality-quantity” model of fertility, we find that birthright citizenship leads to a reduction in immigrant fertility and an improvement in health and socio-emotional outcomes for the children affected by the reform.
