DYNAMIC ANALYSES OF SINGLE MOTHERHOOD

这项研究通过关注单亲母亲的动态性质来研究单亲母亲。 家庭经历，特别是家庭的复杂方式 童年和青春期的变化会影响到性转变 活跃度、生育力和家庭形成。我们通过以下方式审查变化： 直接在可供选择的假说之间进行裁决 关于单身母亲风险的过去和现在的家庭情况； 使用以下模型测试关于持续性与瞬时性的假设 让家庭状况保持不变、下降、增加或 年龄或持续时间的非单调效应；(C)使用动态模型 阐明选择进入和退出的行为机制 共同生育率和婚姻状况；和(D)对 利用母亲/青少年代际传播劣势 数据。 我们有四个具体目标。首先，我们使用了来自国家统计局的数据 青年纵向调查(NLSY)和全国家庭和家庭调查 家庭(NSFH)直接在几个假设之间做出裁决 被先前的研究暗示为单一的关键前因 母亲的身份。第二，我们检验关于连续性和间断性的假设。 在生命过程中，包括直接评估：(A)坚持不懈 幼儿时期在不完整的家庭中成长的影响；(B) 儿童在接下来的一段时间内所经历的暂时性影响 父母离婚、分居或死亡；(C)长期影响，包括 父母离婚、分居或死亡对特定性别的影响；以及 (D)影响持久度或速度的因素 瞬变效应在幅度上有所下降。第三，我们研究了可能 管理妇女年龄分级进入的风险的选择机制， 并退出共同平等和婚姻状态。第四，我们研究了 使用NSFH数据研究单亲母亲的代际影响 要研究的母亲和青少年：(A)父母/子女互动， 特别是儿童和青少年家庭之间的联系 NSFH受访者的经历及其为人父母的能力 约束、影响和监控性行为和约会行为 他们的青春期子女；和(B)各国的甄选机制 在早期成人中使用母子相似性模型的世代 父母及其青春期子女的过渡。

This research studies single motherhood by focusing on the dynamic nature of family experience and, in particular, the complex ways in which family change during childhood and adolescence affects transitions into sexual activity, fertility, and family formation. We examine change by: (a) directly adjudicating between alternative hypotheses about the effect of past and current family situation on the risk of single motherhood; (b) testing assumptions about persistence versus transience using models that let family situation have constant, declining, increasing, or nonmonotonic effects with age or duration; (c) employing dynamic models to clarify the behavioral mechanisms underlying selection into, and exit out of, joint fertility and marital statuses; and (d) modeling the intergenerational-transmission of disadvantage using mother/adolescent data. We have four specific aims. First, we use data from the National Longitudinal Surveys of Youth (NLSY) and National Survey of Families and Households (NSFH) to adjudicate directly between several hypotheses implicated by previous research as critical antecedents of single motherhood. Second, we test hypotheses on continuity and discontinuity in the life course, including direct assessments of: (a) persistent effects of growing up in a nonintact family during early childhood; (b) transient effects experienced by children during the period following a parental divorce, separation, or death; (c) long-term effects, including gender-specific effects, of parental divorce, separation, or death; and (d) factors influencing the degree of persistence or speed with which a transient effect declines in magnitude. Third, we study possible selection mechanisms governing a woman's age-graded risk of entry into, and exit out of, joint parity and marital states. Fourth, we examine the intergenerational consequences of single motherhood using NSFH data on mothers and adolescents to study: (a) parent/child interactions, in particular, the link between the childhood and adolescent family experiences of NSFH respondents and their ability as parents to constrain, influence, and monitor the sexual and dating behaviors of their adolescent children; and (b) selection mechanisms across generations using models of mother/child similarity in the early adult transitions of parents and their adolescent children.
