Despite plausible mechanisms, little research has evaluated potential changes in health behaviors as a result of the Medicaid expansions of the 1980s and 1990s for pregnant women. Accordingly, we provide the first national study of the effects of Medicaid on health behaviors for pregnant women....

We use survey data that have been linked to medical records data and city-level drug prices to estimate the demand for illicit drugs among pregnant women. The prevalence of prenatal drug use based on post partum interviews was much lower than that based on evidence in the mothers' and babies'...

Expenditures on prescription drugs are one of the fastest growing components of national health care spending, rising by almost three-fold between 1995 and 2007. Coinciding with this growth in prescription drug expenditures has been a rapid rise in direct-to-consumer advertising (DTCA), made...

Exploiting changes in welfare policy across states and over time and comparing relevant population subgroups within an econometric difference-in-differences framework, we estimate the causal effects of welfare reform on adult women's illicit drug use from 1992 to 2002, the period during which...

Treatment is highly cost-effective in reducing an individual's substance abuse (SA) and associated harms. However, data from Treatment Episodes (TEDS) indicate that per capita treatment admissions substantially lagged behind increases in heavy drug use from 1992-2007. Only ten percent of...

This paper analyzes the effect of Medicaid eligibility expansions on the health insurance coverage of women giving birth and on the use of prenatal care and infant health, controlling for year and state effects and state-specific trends that may be correlated with expansions in Medicaid...

Basic economic theory suggests that health insurance coverage may cause a reduction in prevention activities, but empirical studies have yet to provide much evidence to support this prediction. However, in other insurance contexts that involve adverse health events, evidence of ex ante moral...

The behavioral economic model presented in this paper argues that the effect of advertising and price differ by past consumption levels. The model predicts that advertising is more effective in reducing consumption at high past consumption levels but less effective at low past consumption...

There is suggestive evidence that rates of major depression have risen markedly in the U.S. concurrent with the rise in obesity. The economic burden of depression, about $100 billion annually, is under-estimated if depression has a positive causal impact on obesity. If depression plays a causal...
