Legal Issues Relating to Teen Fertility

 描述（由申请人提供）：父母参与（PI）法律是广泛的，影响了很大一部分青少年，女性人口。我们将对PI法律对青少年生育的影响进行可以说是最全面和最可信的评估。我们将使用独特的数据和新的方法来研究PI法律是否影响青少年生育能力。具体来说，我们将 使用两种方法获得PI法律对青少年生育率的影响的估计：1989年至2009年期间采用PI法律的州的前后测试比较组方法，以及有和没有PI法律的州的回归不连续研究设计。我们的分析将跨越20年，涵盖了PI法律相对罕见的时期，到PI法律无处不在的时期。我们将能够研究PI法律的效果是否因周围（地理）监管环境而不同，效果是否因法律类型而不同，以及效果是否因法律的严格程度而不同。

 DESCRIPTION (provided by applicant): Parental Involvement (PI) laws are widespread and affect a large fraction of the teen, female population. We will conduct arguably the most comprehensive and credible assessment of the effect of PI laws on teen fertility. We will use unique data and novel methods to study whether PI laws affect teen fertility. Specifically, we will obtain estimates of the effect of PI laws on teen fertility using two approaches: a pre- and post-test with comparison group approach for states that adopted a PI law during the 1989 to 2009 period, and a regression discontinuity research design for states with and without PI laws. Our analysis will span 20 years and cover a period when PI laws were relatively rare to the current period when PI laws are ubiquitous. We will be able to study whether the effect of PI laws differs by the surrounding (geographically) regulatory environment, whether the effect differs by the type of law, and whether the effect differs by the strictness of the law.
