Abstract:
Child maltreatment, which includes both child abuse and child neglect, is a major social problem. This paper focuses on measuring the effects of child maltreatment on crime using data from the National Longitudinal Study of Adolescent Health (Add Health). We focus on crime because it is one of the most socially costly potential outcomes of maltreatment, and because the proposed mechanisms linking maltreatment and crime are relatively well elucidated in the literature. Our work addresses many limitations of the existing literature on child maltreatment. First, we use a large national sample, and investigate different types of abuse in a similar framework. Second, we pay careful attention to identifying the causal impact of abuse, by using a variety of statistical methods that make differing assumptions. These methods include: Ordinary Least Squares (OLS), propensity score matching estimators, and twin fixed effects. Finally, we examine the extent to which the effects of maltreatment vary with socio-economic status (SES), gender, and the severity of the maltreatment.

We find that maltreatment approximately doubles the probability of engaging in many types of crime. Low SES children are both more likely to be mistreated and suffer more damaging effects. Boys are at greater risk than girls, at least in terms of increased propensity to commit crime. Sexual abuse appears to have the largest negative effects, perhaps justifying the emphasis on this type of abuse in the literature. Finally, the probability of engaging in crime increases with the experience of multiple forms of maltreatment as well as the experience of Child Protective Services (CPS) investigation.

Abstract:
This is the first paper to investigate the determinants of the demand for medical care in the People's Republic of China. It uses a data set that consists of detailed characteristics of 6407 urban households, a continuous measure of health care spending, and price. A two-part model and a discrete factor model are used in the estimation. Household characteristics and work conditions impact the demand for medical care. Income elasticity is around 0.3, indicating medical care is a necessity. Medical care demand is price inelastic, and price elasticity is larger in absolute value for poorer households.

This paper provides an analysis of child care subsidies under welfare reform. Previous studies of child care subsidies use data from the pre-welfare-reform period, and their results may not apply to the very different post-reform environment. We use data from the 1999 National Survey of America's Families to analyze the determinants of receipt of a child care subsidy and the effects of subsidy receipt on employment, school attendance, job search, and welfare participation. We analyze the impact on subsidy receipt of household characteristics such as family size and structure, and past participation in welfare. The most important determinant of receipt of a child care subsidy is past receipt, but we cannot determine from our analysis whether this is a causal effect or a result of unobserved heterogeneity. Ordinary least squares estimates that treat subsidy receipt as exogenous show an effect of subsidy receipt of about 13 percentage points on employment. Two stage least squares estimates that treat subsidy receipt as endogenous and use county dummies as identifying instruments show an effect of 32 percentage points. We present some evidence that is consistent with the assumption that county dummies are valid identifying instruments, and some evidence that is inconsistent with the assumption.

Previous studies of child care subsidies use data from the pre-welfare-reform period, and their results may not apply to the very different post-reform environment. We use data from the 1997 National Survey of America's Families to analyze the determinants of receipt of a child care subsidy and the effects of subsidy receipt on employment, school attendance, job search, and welfare participation. We analyze the impact on subsidy receipt of household characteristics such as family size and structure, and past participation in welfare. Ordinary least squares estimates show positive and significant effects of subsidy receipt on employment, school enrollment, and welfare participation. Two stage least squares estimates that treat subsidy receipt as endogenous and use county dummies as identifying instruments show much less evidence that subsidy receipt affects these outcomes.

Abstract:
This paper examines the impact of actual subsidy receipt of single mothers on their joint employment and child care mode decisions in the post-welfare reform environment, which places a high priority on parental choice with the quality and type of care chosen. Results indicate that single mothers are highly responsive to child care subsidies by increasing their employment while moving from parental and relative care to center care in the process.

Abstract:
This paper examines the effects of alcohol consumption on employment and wages for males and females in Russia. Both cross sectional and fixed-effects models are estimated utilizing data from the Russia Longitudinal Monitoring Survey. The results from the models that do not control for unobserved heterogeneity indicate that alcohol consumption has a positive impact on employment and wages. Further, there is some evidence in favor of an inverse U-shaped relationship between alcohol consumption and the labor market outcomes. Once the unobserved heterogeneity is controlled for using fixed effects, the positive association diminishes for the employment models for males and females. For the wage models, controlling for unobserved heterogeneity strengthens the positive impact of alcohol consumption both in significance and magnitude for males, while the reverse is true for females. However, the inverse U-shaped relationship obtained in cross-sectional models no longer exists. The results underline that unobserved heterogeneity plays an important role on the relationship between alcohol consumption and labor market behavior for both males and females. The findings are robust to model specifications and various alcohol consumption measures.

Abstract:
Using data from three waves of Add Health we find that being very attractive reduces a young adult's (ages 18-26) propensity for criminal activity and being unattractive increases it for a number of crimes, ranging from burglary to selling drugs. A variety of tests demonstrate that this result is not because beauty is acting as a proxy for socio-economic status. Being very attractive is also positively associated adult vocabulary test scores, which suggests the possibility that beauty may have an impact on human capital formation. We demonstrate that, especially for females, holding constant current beauty, high school beauty (pre-labor market beauty) has a separate impact on crime, and that high school beauty is correlated with variables that gauge various aspects of high school experience, such as GPA, suspension or having being expelled from school, and problems with teachers. These results suggest two handicaps faced by unattractive individuals. First, a labor market penalty provides a direct incentive for unattractive individuals toward criminal activity. Second, the level of beauty in high school has an effect on criminal propensity 7-8 years later, which seems to be due to the impact of the level of beauty in high school on human capital formation, although this second avenue seems to be effective for females only.

Abstract:
This paper provides a comprehensive analysis of employment and child care payment decisions of single mothers in the early post-welfare reform environment, using data from the National Survey of America's Families (NSAF). I develop and estimate a model that examines the effects of the price of child care and the wage rate on employment decision as well as the decision to use paid child care among single mothers. The model distinguishes between the full-time and part-time employment decisions as well as the prevailing wages in these two employment markets. A semi-parametric random effects estimator and the Gaussian Quadrature are used together to estimate the system of equations for the discrete outcomes of full-time and part-time employment, and child care payment, and the linear equations of the price of child care, and part-time and full-time wages in a unified framework. The econometric model also controls for the endogeneity of child care subsidy receipt and adjusts the hourly price of child care for the amount of subsidy for mothers who receive one. The results show that full-time working mothers are more sensitive to the price of child care than part-time working mothers. A lower price of child care leads to increases in overall employment and the use of paid child care. However, much of the increase in employment is in the form of full-time employment. An increase in the full-time wage rate leads to increases in overall employment and the use of paid child care. The effects of full-time wage rate are estimated to be much larger than those of the price of child care. Part-time wage effects are found to be so small to have significant implications.

Abstract:
Using a nationally-representative panel data set of U.S. high school students (AddHealth data) that contains a relatively large sample of siblings and twins, the paper investigates the impacts of gun availability at home and individual drug use on robbery, burglary, theft and damaging property for juveniles. Using a variety of fixed-effects models that exploit variations over time and between siblings and twins, the results show that gun availability at home increases the propensity to commit crime by about two percentage points for juveniles but has no impact on damaging property. The results indicate that it is unlikely that gun availability is merely a measure of the unobserved home environment because gun availability does not influence other risky or bad behaviors of juveniles such as smoking, drinking and fighting, being expelled from school, lying, and having sex. No support is found for the hypothesis that gun availability decreases the propensity for being victimized. In fact, the results show that having access to guns increases the probability of being cut or stabbed by someone and of someone pulling a knife or gun on the juvenile. Estimates obtained from models that exploit variations over time and between siblings and twins indicate that drug use has a significant impact on the propensity to commit crime. We find that the median impact of cocaine use on the propensity to commit various types of crimes is 11 percentage points. The impact of using inhalants or other drugs is an increase in the propensity to commit crime by 7 and 6 percentage points, respectively.

Abstract:
This paper estimates the effect of child care subsidies on the standard work decision of single mothers and examines whether this effect differs between welfare recipients and nonrecipients. The analysis uses data from the 1999 National Survey of America's Families. Results suggest that child care subsidy receipt is associated with a 6.9 percentage point increase in the probability of single mothers' working at standard jobs. When the effect of subsidy receipt is allowed to differ between welfare recipients and nonrecipients, results indicate that welfare recipients who are offered a child care subsidy are 14 percentage points more likely to work at standard jobs than others. Among nonrecipients, child care subsidy receipt increases standard work probability by only 1.8 percentage point. These findings underscore the important role of child care subsidies in helping low income parents, especially welfare recipients, find jobs with conventional or standard schedules. The results also lend support to the policy of giving priority to welfare recipients for child care subsidies. Results are found to be robust to several specification checks.

Abstract:
Using a data set from the post welfare reform environment (the 1999 National Survey of America's Families), this paper investigates the impact of child care subsidies on the standard work (i.e., work performed during the traditional work hours of 8 a.m. and 6 p.m. through Monday and Friday) decision of single mothers and tests whether this impact differs between welfare recipients and nonrecipients. The econometric strategy accounts for sample selection into the labor force and the potential endogeneity of child care subsidy receipt and welfare participation. Results suggest that child care subsidies are associated with a 6 percentage point increase in the probability of single mothers working at standard jobs. When the impact of subsidies is allowed to differ between welfare recipients and non-recipients, results indicate that welfare recipients are 14 percentage points more likely to work at standard jobs than others when they are offered a child care subsidy. Among non-recipients, child care subsidies increase standard work probability by only 1 percentage point. These results underscore the importance of child care subsidies helping low-income parents, especially welfare recipients, find jobs with conventional or standard schedules and lend support to the current practice of states' giving priority to welfare recipients for child care subsidies. Results are found to be robust to numerous specification checks.

Abstract:
Although there is a sizeable literature of the effect of private school attendance on academic student outcomes, there is a dearth of studies of the impact of school sector on non-academic outcomes. Using a rich data set, we analyze the impact of Catholic school attendance on the likelihood that teens use or sell drugs, commit property crime, have sex, join gangs, attempt suicide, and run away from home. Controlling for a host of personal and family background characteristics and adjusting for the endogeneity of sector choice, we cannot find evidence that Catholic schooling leads to a lower incidence of these risky behaviors among teenagers.

Abstract:
This paper uses a rich employer-employee matched data set to investigate the existence and the extent of nonprofit and part-time wage and compensation differentials in child care. The empirical strategy adjusts for workers' self-selection into the for-profit or nonprofit sectors, into full-time or part-time work, as well as for unobserved worker heterogeneity using a discrete factor model. We find differences between the regimes (full-time for-profit, full-time nonprofit, part-time for-profit, part-time nonprofit) in the manner in which human capital characteristics of the workers are rewarded. There is substantial variation in wages as a function of employee characteristics, and there is variation in wages within sectors. The results indicate that part-time jobs are "good" jobs in center-based child care, and there exist nonprofit wage and compensation premiums, which support the property rights hypothesis.

Abstract:
This paper provides a comprehensive analysis of the link between suicidal behaviors and labor market productivity of young adults in the United States. Using data from the National Survey of Adolescent Health (Add Health), we estimate the effects of suicide thoughts and suicide attempts on the work and schooling activities of young adults as well as on their hourly wage rates. The richness of the data set allows us to implement several strategies to control for unobserved heterogeneity and the potential reverse causality. These include using a large set of control variables that are likely to be correlated with both the suicidal behavior and the outcome measures, an instrumental variables method, and a twin fixed effects analysis from the subsample of twin pairs contained in the data. The longitudinal nature of the data set also allows us to control for past suicide thoughts and attempts of the individuals from their high school years as well as the suicide behaviors of the members of their family. Results from the different identification strategies consistently indicate that both suicide thoughts and suicide attempts decrease the hourly wage rate and the probability that a young adult individual works and/or attends school. The results are found to be robust to various specification tests.

Abstract:
Child care subsidies are an important part of federal and state efforts to move welfare recipients into employment. One of the criticisms of the current subsidy system, however, is that it overemphasizes work and does little to encourage parents to purchase high-quality child care. Consequently, there are reasons to be concerned about the implications of child care subsidies for child development. In this paper, we provide a systematic assessment of the impact of subsidy receipt on a wide range of child outcomes. Drawing on rich data from the Early Childhood Longitudinal Study, we document a negative relationship between child care subsidies and child development. In particular, our results suggest that subsidy receipt in the year before kindergarten lowers reading and math test scores and increases a variety of behavior problems at kindergarten entry. Some of these negative effects persist to the end of kindergarten. A tentative explanation for the poorer outcomes is that subsidized children are more likely to receive intense exposure to low-quality child care.

Abstract:
Child care subsidies play a critical role in facilitating the transition of disadvantaged mothers from welfare to work. However, little is known about the influence of these policies on children's health and well-being. In this paper, we study the impact of subsidy receipt on low-income children's weight outcomes in the fall and spring of kindergarten. The goals of our empirical analysis are twofold. We first utilize standard OLS and fixed effects methods to explore body mass index as well as measures of overweight and obesity. We then turn to quantile regression to address the possibility that subsidy receipt has heterogeneous effects on children's weight at different points in the BMI distribution. Results suggest that subsidy receipt is associated with increases in BMI and a greater likelihood of being overweight and obese. We also find substantial variation in subsidy effects across the BMI distribution. In particular, child care subsidies have no effect on BMI at the lower end of the distribution, inconsistent effects in the middle of the distribution, and large effects at the top of the distribution. Our results point to the use of non-parental child care, particularly center-based services, as the key mechanism through which subsidies influence children's weight outcomes.

Although there is a sizeable literature on the effect of private school attendance on academic student outcomes, the number of studies that investigate the impact of school sector on non-academic outcomes is limited. Using a rich data set, we analyze the impact of Catholic school attendance on the likelihood that teenagers use or sell drugs, commit property crime, have sex, join gangs, attempt suicide, and run away from home. We employ propensity score matching methods to control for the endogeneity of school choice. Catholic school attendance reduces the propensity to use cocaine and to have sex for female students. However, it increases the propensity to use and sell drugs for male students.

Abstract:
A number of researchers point to the anticipation of early death, or a sense of "futurelessness," as a contributing factor to youth crime and violence. Young people who perceive a high probability of early death, it is argued, may have little reason to delay gratification for the promise of future benefits, as the future itself is discounted. Consequently, these young people tend to pursue high-risk behaviors associated with immediate rewards, including crime and violence. Although existing studies lend empirical support to these arguments and show a statistical relationship between anticipated early death and youth crime, this support remains tentative. Moreover, a number of questions remain regarding the interpretation of this relationship, the meanings that offenders attach to the prospect of early death, and the causal mechanisms that link anticipated early death to youth crime. In this paper, we address the limitations of previous studies using a multi-methods approach, involving the analyses of national survey data and in-depth interviews with active street offenders.

Abstract:
The total value of life lost due to death because of waiting for an organ transplant is greater than $4 billion annually in the United States, and the excess demand for organs has been increasing over time. To shed light on the factors that impact the willingness to donate an organ, we analyze data from the United States and the European Union. The rate of willingness to donate an organ is 38 % among young adults in the U.S., and it is 42 % in Europe. Interesting similarities emerge between the U.S. and Europe regarding the impact of gender, political views and education on the willingness to donate. In the U.S. Blacks, Hispanics and Catholics are less likely to donate. In Europe, individuals who reveal that they are familiar with the rules and regulations governing the donation and transplantation of human organs are more likely to donate. In both data sets individuals who had some encounter with the health care sector %u2013either through a recent emergency room visit (in the U.S.), or perhaps because of a long-standing illness (in the E.U), are more likely to become organ donors. Mother%u2019s education has a separate positive impact.

Abstract:
In the U.S. teen mothers are more likely to give birth to low birth weight babies than non-teen mothers. There is also substantial evidence that smoking is a risk factor correlated with low birth weight. Low birth weight is a costly outcome in both the short and long term for parents, children, and society at large. This paper examines the causal link between teen age smoking behavior and low birth weight. We use a variety of empirical techniques including fixed effects and a matching estimator to identify the impact of smoking on babies of teen and non-teen mothers. We find that both OLS and matching estimator results yield large impacts of smoking on birth weight for teens and adults. However, when we control for unobservables through a fixed effects model, the impact of smoking on birth weight is diminished and there are relatively small differences in the impact of smoking on birth weight between teens and non-teens.

Abstract:
This article examines the effect of child care subsidies on the standard work decision of single mothers. Results suggest that child care subsidy receipt is associated with about a 7 percentage point increase in the probability of working at a standard job. When the effect of subsidy receipt is allowed to differ between welfare recipients and nonrecipients, results indicate that subsidy receipt has a large and positive effect among welfare recipients, whereas the effect on nonrecipients is much smaller. These findings underscore the importance of child care subsidies in helping low-income parents, especially welfare recipients, gain standard employment.

Abstract:
This paper examines the effect of body composition on wages. We develop measures of body composition – body fat (BF) and fat-free mass (FFM) – using data on bioelectrical impedance analysis (BIA) that are available in the National Health and Nutrition Examination Survey III and estimate wage models for white respondents in the National Longitudinal Survey of Youth 1979. Previous research used body size or BMI for measuring obesity despite the growing concern in the medical literature that BMI-based measures do not distinguish between body fat and fat-free body mass and that BMI does not adequately control for non-homogeneity inside human body. Therefore, measures used in this paper represent a useful alternative to BMI-based proxies of obesity. This paper also contributes to the growing literature on the role of non-cognitive skills on wage determination. Our results indicate that calculated BF is unambiguously associated with decreased wages for both males and females among whites We also present evidence indicating that FFM is consistently associated with increased wages. We show that these results are not the artifacts of unobserved heterogeneity. Finally, our findings are robust to numerous specification checks and to a large number of alternative BIA prediction equations from which the body composition measures are derived.

Abstract:
Obesity is associated with serious health problems, and it can generate adverse economic outcomes. We analyze a nationally-representative sample of young American adults to investigate the interplay between obesity, wages and self-esteem. Wages can be impacted directly by obesity, and they can be influenced by obesity indirectly through the channel of obesity to self-esteem to wages. We find that female wages are directly influenced by body weight, and self-esteem has an impact on wages in case of whites. Being overweight or obese has a negative impact on the self-esteem of females and of black males. The results suggest that obesity has the most significant impact on white women’s wages.
