Subdermal contraceptive implants and repeat teenage motherhood: Evidence from a major maternity hospital‐based program in Uruguay
研究乌拉圭一家妇产医院的皮下避孕植入项目对青少年母亲重复生育的影响，发现该干预使母亲在48个月内再次生育的概率降低10个百分点。
Teenage fertility is a social problem because of its private and public costs in countries of different development levels. Reductions in adolescent birth rates do not necessarily follow drops in overall fertility due to the demographic transition model. This paper analyses the impact of a subdermal contraceptive program on repeat teenage motherhood. Using a regression discontinuity design, we find that the intervention reduced mothers' likelihood of having another child in the next 48 months by 10 percentage points. This reduction is not random, and we also identify small positive selection in subsequent births.
