Clarke and Strauss (1998), among others, have determined that the magnitude of financial transfers to unwed mothers is positively related to out‐of‐wedlock fertility rates. Increases in fertility rates must be accompanied by increases in unprotected sex, and unprotected sex allows for the spread of sexually transmitted diseases. We hypothesize that states with relatively greater welfare payments under the old Aid to Families with Dependant Children (AFDC) program are associated with higher rates of heterosexually contracted human immunodeficiency virus (HIV). Using data for 26 reporting states from 1993 to 1996, our weighted instrumental variables estimates with clustered standard errors are consistent with our hypothesis. (JEL D1, I38)
This article mainly examines the effect(s) of legal drug misuse on work absenteeism, which has a connecting influence to work productivity. Also, the analysis compares the effects of legal drug use (e.g., tranquilizers) on work absences to that of a commonly used, but illegal drug, marijuana. Utilizing a large dataset from the NSDUH (National Survey on Drug Use and Health), and controlling for several demographic and labor market-related variables, our results indicate that legal drug use (for nonmedical reasons) leads to an increase in work absenteeism, as does marijuana. In some instances, legal drug use has a greater effect on work absenteeism that does marijuana.
Economists have long studied the determinants and effects of income transfers. This article examines an indirect effect of welfare payments on participating individuals: an increase in the incidence of sexually transmitted disease (STD) rates.Several studies have found a significant and positive link between the size of welfare benefits and out-of-wedlock fertility rates. Higher welfare payments reduce the cost of bearing and raising a child, and thus reduce the full cost of engaging in unprotected sex. An unintended consequence of unprotected sex is exposure to contagious diseases. This implies that states with higher welfare payments per child will experience higher rates of STDs.We test this hypothesis using statewide data on the incidence of three types of bacterial STDs, chlamydia, gonorrhea, and syphilis, for the years 1994 through 1998. The empirical specification is based on the standard microeconomic model of utility-maximizing behavior. The included explanatory variables are demographic proxies reflecting differences in state population characteristics. These characteristics capture unobservable or intrinsically unmeasureable differences in the perceived costs and benefits of engaging in unprotected sex.The explanatory variable of primary interest is the size of the real welfare payment per recipient. Our empirical results indicate that states with higher real welfare payments are associated with greater rates of STDs.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
