This article uses a large data set of sibling births to examine when mothers must quit smoking in pregnancy to deliver healthy babies. It applies sibling fixed effects models to provide robust evidence that smoking cessation in the first trimester has a negligible effect on infant health, but...

This paper studies whether adolescents who are more aware of the risks on substance use in the early teenage years are later less likely to turn into binge drinkers or smokers. It also examines if reduction in substance use, due to high risk perception among adolescents, consequently improves...

We examine the relationship between the prices paid by households and their shopping patterns measured in terms of shopping frequency and the range of stores visited. We use the TNS data which allows us to control for household heterogeneity. The main contribution of the paper is that we find...

A key goal of US public health policies is to reduce costly adverse birth outcomes to which prenatal smoking is a crucial contributor. This study is the first to evaluate the impacts of a minimum cigarette purchase age of 21 implemented in the state of Pennsylvania on prenatal smoking and infant...

Objectives: Smoking during pregnancy is a key preventable risk contributor to poor infant health. Our study presents a full dynamic relationship between the timing of prenatal smoking cessation or reduction and infant birth weight. Methods: Using a large representative dataset of birth cohort in...

In the United States, the high prevalence of unhealthy preconception body weight and inappropriate gestational weight gain among pregnant women is an important public health concern. However, the relationship among pre-pregnancy BMI, gestational weight gain, and newborn birth weight has not been...

A key target of the U.S. health policies is to reduce costly adverse birth outcomes to which prenatal smoking is one of the most signicant contributors. This paper represents the rst attempt to examine whether implementing the minimum cigarette purchase age of 21 can curb smoking among young...

This paper uses a unique large panel data of sibling births to provide new evidence on when prenatal smokers must quit smoking to deliver the healthy newborn. In a series of the mother fixed effect estimation, I find robust results that early cessation in the first trimester nullifies the...

The marketing literature generally supports the view that price elasticity varies from product/brand to product/brand, influential work by Ehrenberg and England (1990) suggests that elasticities show little variation even when prices themselves are changing. The paper reports an investigation of...
