In this competing continuation application, we propose to build on our previous empirical investigations of the causal effects of teenage childbearing in the U.S., undertaking the following expanded and new specific aims: 1. Estimate the effect of the failure to delay childbearing on the physiological, cognitive, socioemotional, and behavioral development of the children born to teenage women in the U.S. using the robust, non-parametric bounding statistical methods derived from the miscarriages-as-a-natural-experiment evaluation design developed in the initial funding period of this grant. 2. Expand on our initial research program to consider the effects of the failure to delay early childbearing on a set of maternal (and, more generally, parental) outcomes which the child development literature has argued are important inputs into the child's development. 3. Extend, and in some cases, replicate with new data, our initial analysis on the effects of early childbearing on maternal outcomes, measured at various stages of the teen mothers life cycles (i.e., at different ages of women who became teen mothers and of women in our comparison groups), using the same evaluation design developed during our initial funding period. 4. Further assess and test the validity of our miscarriages-as-a-natural- experiments evaluation design for identifying the causal effect of the failure of teen mothers to delay their childbearing. Our empirical analysis will make primary use of three different data sources: (i) the National Longitudinal Survey of Youth (NLSY79); (ii) data sets which comprise the National Maternal and Infant Health Survey (NMIHS); and (iii) Detailed Files of the U.S. Vital Statistics Natality (Live Birth) data, 1968-94.

在这个竞争性的延续申请中，我们建议建立在我们的 以往的经验调查的因果关系的青少年 在美国生孩子，开展下列扩大和新的 具体目标：1. 估计未能延迟的影响 生育对生理、认知、社会情感和 美国少女所生孩子的行为发展 使用强大的，非参数边界统计方法推导出 从自然流产实验评估设计 在此资助的初始资助期内开发。 2. 扩大 我们最初的研究计划是考虑失败的影响， 推迟早育对一组产妇（和，更普遍地说， 父母）的结果，儿童发展文献认为， 对儿童发展的重要贡献。 3. 延伸，在一些 的情况下，复制与新的数据，我们的初步分析的影响， 早育对孕产妇结局的影响，在不同阶段进行测量， 青少年母亲的生命周期（即，在不同年龄的女性中， 成为青少年母亲和我们对照组中的女性），使用 在我们最初的资助期间开发了相同的评估设计。 4. 进一步评估和测试我们的流产的有效性，作为一个自然的， 实验评价设计，以确定因果关系的影响 未成年母亲未能推迟生育。 我们的实证 分析将主要利用三个不同的数据来源：（一） 全国青年纵向调查（NLSY 79）;（二） 包括全国母婴健康调查; (iii)美国人口动态统计出生率（Live Birth） 数据，1968-94。
