Previous work based on conjectural responses of minors predicted that the 2003 Texas requirement for parental consent for state-funded birth control to minors would lead to a large increase in underage pregnancies. We use state- and county-level data to test this prediction. The latter allow us to compare the impact of parental consent in counties with and without state-funded family planning clinics. We control for characteristics systematically correlated with the presence of state-funded clinics by combining difference-in-difference estimation with propensity score-weighted regressions. The evidence suggests that the parental consent mandate led to a large decrease in attendance at family planning clinics among teens but did not lead to an increase in underage pregnancies.
先前基于未成年人推测性回应的研究预测，2003 年德克萨斯州要求未成年人获得父母同意才能获得政府资助的避孕措施，这将导致未成年怀孕人数大幅增加。我们使用州和县一级的数据来检验这一预测。后者使我们能够比较在有和没有政府资助计划生育诊所的县，父母同意的影响。我们通过结合差分法估计和倾向得分加权回归，控制与政府资助诊所存在相关的特征，对这些数据进行了处理。证据表明，父母同意授权令导致青少年参加计划生育诊所的人数大幅减少，但并未导致未成年怀孕人数增加。
