As female participation in the labor force continues to grow in the US, so too does reliance on non-parental child care. However, the high cost of child care has impeded the ability of many working mothers to find sufficient child care for their children. As a result, as recently as 1998 over eight million children ages five to fourteen spent time without adult supervision on a regular basis in the US. I examine the effect of the lack of adult supervision after school on panel of school-age children using ordinary least squares and fixed effect estimation. I find that children with adult supervision are less likely to skip school, use alcohol or marijuana, steal something or hurt someone. These findings suggest that expanding after school or child care programs typically geared to preschool age children to accommodate more school age children may have important consequences for their human capital development and labor market outcomes later in life....The information on adolescent behavior and adult supervision is gathered as part of the child/young adult questionnaire of the NLSY administered every other year from 1986-1998. Questions in the survey with respect to supervision and adolescent behavior(skipping school, getting drunk/high, stealing something, and hurting someone badly) refer to the period one year prior to the date of interview. Data on accidents are available for children of all ages and are gathered from the child's mother.

We examine U.S. and Canadian children with symptoms of Attention Deficit Hyperactivity Disorder (ADHD), the most common child mental health problem. Our work offers a number of innovations. First we use large national samples and focus on an ADHD screener that was administered to all children rather than on small samples of diagnosed cases. Second, we address omitted variables bias by estimating sibling-fixed effects models as well as instrumenting for possible measurement error in reports of ADHD symptoms. Third, we examine a range of outcomes and compare the effects of ADHD to the effects of physical health conditions. Fourth, we ask how the effects of ADHD and treatment for ADHD are mediated by income. We find that ADHD has large negative effects on test scores and schooling attainment and the effects are much worse than those of physical health problems. The results are qualitatively similar in the U.S. and Canada, and are robust to many changes in specification. The test scores of higher income children suffer as much from ADHD as those of lower income children, though high income children are less likely to be retained in grade. Surprisingly, there appears to be little effect of income on the probability of treatment conditional on hyperactivity scores. A third finding is that even children with relatively low levels of symptoms suffer negative effects. The severity of the effects and the pervasiveness of the symptoms suggest that efforts to find better ways to teach the relatively small number of children diagnosed with ADHD could have a larger payoff in terms of improving the academic outcomes of large numbers of children with milder symptoms.

3.	Teenage Childbearing and Its Life Cycle Consequences: Exploiting a Natural Experiment Working Paper, Department of Economics, University of California - Los Angeles, July 2004. Also: http://www.econ.ucla.edu/hotz/working_papers/teen.pdf Cohort(s): NLSY79 Publisher: Department of Economics, University of California, Los Angeles Keyword(s): Adolescent Fertility; Childbearing, Adolescent; Family Resources; School Dropouts; Variables, Instrumental Permission to reprint the abstract has not been received from the publisher. We exploit a "natural experiment" associated with human reproduction to identify the causal effect of teen childbearing on the socioeconomic attainment of teen mothers. We exploit the fact that some women who become pregnant experience a miscarriage and do not have a live birth. Using miscarriages an instrumental variable, we estimate the effect of teen mothers not delaying their childbearing on their subsequent attainment. We find that many of the negative consequences of teenage childbearing are much smaller than those found in previous studies. For most outcomes, the adverse consequences of early childbearing are short-lived. Finally, for annual hours of work and earnings, we find that a teen mother would have lower levels of each at older ages if they had delayed their childbearing.

Early Parental Time Investments in Children's Capital Development: Effects of Time in the First Year on Cognitive and Non-Cognitive Outcomes Working Paper No. 806, Department of Economics, University of California - Los Angeles, 2000.

Based on recent neuropsychological literature, this study measures the effects of early parental time investments on children's cognitive and non-cognitive development. This study offers three innovations. First, time investments are not permitted to be substitutable over time. Second, short and long term cognitive and non-cognitive outcomes are considered. Third, a household fixed effect is constructed to capture the unobserved heterogeneity of caregivers and children. This offers a lower bound of the true effect of time investments. Using the National Longitudinal Survey Child-Mother file, the results are consistent with neuropsychological evidence. They suggest that uninterrupted parental time investments for up to one year offer lasting benefits, particularly for non-cognitive outcomes, but longer spells of uninterrupted investments are of questionable value.
