The Role of Alcohol and Drug Consumption in Determining Physical Fights and Weapon Carrying by Teenagers

The purpose of this study is to examine the question of whether alcohol or drug use causes teenagers to engage in violent behaviors as measured by physical fighting, carrying a gun, or carrying other types of weapons. Simple OLS estimation of the effects of drug and alcohol consumption on violence may be biased because of the possibility that both behaviors are determined by unmeasured individual traits. Two-stage least squares estimates are employed to establish causality. This method first predicts consumption using the prices of beer, marijuana and cocaine and then enters predicted consumption in the violence equation. This technique allows the consumption measures to be purged of their correlation with unobserved characteristics. Data come from the National School-Based Youth Risk Behavior Surveys, which are nationally representative samples of high school students. Results indicate that beer and marijuana consumption do cause teens to engage in more physical fights, while cocaine use appears to have no relationship. None of the substances lead to increased probabilities of carrying a gun or other weapon.

The Price of Alcohol, Wife Abuse, and Husband Abuse

Alcohol consumption has been frequently linked to family violence. The purpose of this paper is to examine the direct relationship between the price of alcohol, which determines consumption, and violence towards spouses. The data come from the 1985 cross section and the 1985-1987 panel of the National Family Violence Survey. The 1985 data are a nationally representative sample while the panel oversamples violent individuals. Dichotomous indicators of severe violence towards wives and husbands are used. A reduced for violence equation is estimated, and individual-level fixed effects are used to control for unobserved characteristics in the panel. A consistent result that emerges from this paper is that an increase in the pure price of alcohol, as measured by a weighted average of the price of alcohol from beer, wine, and liquor, will serve to reduce severe violence aimed at wives. By contrast, the evidence on the propensity of an increase in the price of alcohol to lower violence towards husbands is mixed. When individual level characteristics are not controlled for, the price is not a predictor of violence towards men. However, once the individual traits are controlled for, a negative relationship between the price and violence emerges.

Does the Length of Maternity Leave Affect Maternal Health?

The objective of this paper is to investigate the impact of the length of maternity leave on maternal health in a sample of working mothers. Two measures of depression and a measure of overall health are used to represent maternal health. Ordinary Least Squares models provide baseline estimates, and instrumental variables models account for the potential endogeneity of the return-to-work decision. The findings suggest that returning to work later may reduce the number or frequency of depressive symptoms, but the length of time before returning to work is not associated with a lower probability of being a likely case of clinical depression. Similarly, there is little evidence that longer maternity leave impacts physical and mental health as measured by frequent outpatient visits during the first six months after childbirth.

Are Mental Health Insurance Mandates Effective? Evidence from Suicides

Many states have passed laws mandating insurance companies to provide or offer some form of mental health benefits. These laws presumably lower the price of obtaining mental health services for many adults, and as a result, might improve health outcomes. This paper analyzes the effectiveness of mental health insurance mandates by examining the influence of mandates on adult suicides, which are strongly correlated with mental illness. Data on completed suicides in each state for the period 1981-2000 are analyzed. Ordinary least squares and two-stage least squares results show that mental health mandates are not effective in reducing suicide rates.

Incentives in Obesity and Health Insurance

The obesity rate in the United States has risen significantly in the past few decades. While a number of economic causes for the rise in obesity have been explored, little attention has been on the role of health insurance per se. This paper examines obesity in the context of a model where health insurance status can influence body weight. We attempt to isolate the effects of ex ante moral hazard, where people with health insurance may change their behaviors towards weight control. We use data from the Behavioral Risk Factor Surveillance System from 1993 to 2002 to determine the potential effect of having health insurance on measures of body weight. In our analyses, we control for a variety of confounding factors that may influence body weight and address the endogenous nature of health insurance. Our results show evidence that having insurance is associated with higher body mass (particularly for those above the poverty threshold) and an increased probability of being overweight. However, we find no evidence that having insurance affects the probability of being obese.

Suicidal Behavior and the Labor Market Productivity of Young Adults

This paper provides a comprehensive analysis of the link between suicidal behaviors and human capital formation of young adults in the United States. Using data from the National Longitudinal Study of Adolescent Health, we estimate the effects of suicide thoughts and attempts on the probability of engaging in work or school. 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 suicidal behavior and the outcome measures, an instrumental variables method, and a 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 suicidal thoughts and suicide attempts of the individuals from their high school years as well as the suicidal behavior of their family members. Results from the different identification strategies consistently indicate that both suicide thoughts and suicide attempts decrease the likelihood a young adult individual engages in work or schooling.

Medicaid Policy Changes in Mental Health Care and Their Effect on Mental Health Outcomes

In recent years, Medicaid has experienced a dramatic increase in spending on prescription drugs in general and psychotropic medications in particular. The purpose of this study is to examine the effects of increased Medicaid spending on psychotropic drugs on improving the mental health and well-being of participants at the population level. Specifically, we study the effect on outcomes that are strongly correlated with mood disorders, including depression, and Attention Deficit/Hyperactivity disorder, controlling for concomitant increases in Medicaid eligibility thresholds and expansion into managed care for mental health services. Knowledge of the effects of changes in the Medicaid program is crucial to policymakers as they consider implementing and expanding mental health services. Our results show that increased spending on antidepressants and stimulants are associated with improvements in some outcomes, but not in others.

The Effect of Child Access Prevention Laws on Non-Fatal Gun Injuries

Many states have passed child access prevention (CAP) laws, which hold the gun owner responsible if a child gains access to a gun that is not securely stored. Previous CAP law research has focused exclusively on gun-related deaths even though most gun injuries are not fatal. We use annual hospital discharge data from 1988-2001 to investigate whether CAP laws decrease non-fatal gun injuries. Results from Poisson regressions that control for various hospital, county and state characteristics, including state-specific fixed effects and time trends, indicate that CAP laws substantially reduce non-fatal gun injuries among both children and adults. Our interpretation of the estimates as causal impacts is supported by the absence of effects on self-inflicted gun injuries among adults, non-gun self-inflicted injuries, and knife assaults, the failure of violent crime levels and law leads to attain significance or alter estimated law coefficients, and larger coefficient magnitudes in states where the law covers older children.

The Effects of Alcohol Regulation on Physical Child Abuse

The purpose of this paper is to examine the effects of alcohol regulation on physical child abuse. Given the established relationship between alcohol consumption and violence, the principal hypothesis to be tested is that an increase in the price of alcohol will lead to a reduction in the incidence of violence. We also examine the effects of measures of the ease of obtaining alcohol, illegal drug prices, and the socio-demographic characteristics of the parent on the incidence of child abuse. Data on violence come from the 1976 and 1985 Physical Violence in American Families surveys. We estimate a reduced form model where violence is affected by the state excise tax rate on beer and other regulatory variables, and a structural model where violence is determined partly by consumption. Both equations are estimated separately for mothers and fathers. Results indicate that increases in the beer tax may decrease the incidence of violence committed by females but not by males. This is consistent with our second finding that violence by females increases with alcohol consumption while violence by males is not sensitive to changes in consumption.

Alcohol Regulation and Violence on College Campuses

This study focuses on the effects of variations in alcoholic beverage prices among states of the United States on violence on college campuses. The principal hypothesis tested is that the incidence of violence is negatively related to the price of alcohol. This hypothesis is derived from two well established relationships: the positive relationship between alcohol and violence and the negative relationship between the use of alcohol and its price. The data employed in the study are the 1989, 1990, and 1991 Core Alcohol and Drug Surveys of College Students. They contain almost 120,000 college students from approximately 200 colleges and universities throughout the United States and have measures of alcohol use and the adverse consequences of its use. These adverse consequences include the following indicators of violence: getting in trouble with the police, residence hall, or other college authorities; damaging property or pulling a fire alarm; getting into an argument or a fight; and taking advantage of another person sexually or having been taken advantage of sexually. The principal finding is that the incidence of each of these four acts of violence is inversely related to the price of beer in the state in which the student attends college.
