Does single motherhood adversely affect infant health? This question is not easy to answer because of the endogeneity of coresidence during pregnancy. In this paper, we exploit quasi-natural variation in single motherhood from the moment of conception to that of birth arising from marriageable...

This paper documents an important unintended consequence of expanding contraceptive access; namely that it creates positive selection in the health of the children being born. I use a family planning intervention which gave thousands of long-acting reversible contraceptives to reproductive-age...

This paper uses the implementation of a privately funded family planning program in Colorado to demonstrate that expanding access to long-acting reversible contraceptives to lower income women creates positive selection in the health of the children being born, reducing the rates of extremely...

Studies have estimated the relationship between psychological stress and birth weight by exploiting natural disasters and terrorist attacks, both of which could affect fetal health through other channels. Using data from the National Vital Statistics System for the period 1969-2004, we estimate...

Exploiting recent concentration of flight patterns under a new Federal Aviation Administration policy (called NextGen), we examine the impact of exposure to excessive noise levels on birth outcomes. Using birth records that include mothers’ home addresses to measure airport proximity, we find...

This paper is one of the first to examine the associations between prenatal sunshine exposure and birth outcomes, specifically the incidence of low birth weight (LBW) and small for gestational age (SGA), based on a nationally representative birth record dataset in China. During the sample period...

Flint changed its public water source in 2014, causing severe water contamination. We estimate the effect of in utero exposure to polluted water on health at birth using the recent Flint water crisis as a natural experiment. Matching vital statistics birth records with various sources of data,...

This paper uses microdata from Brazilian natality and mortality vital statistics between 2000 and 2010 to estimate the impact of in-utero exposure to local violence – measured by homicide rates - on birth outcomes. The estimates show that exposure to violence during the first trimester of...

We investigate the association between prepregnancy obesity and birth outcomes using fixed effect models comparing siblings from the same mother. A total of 7,496 births to 3,990 mothers from the National Longitudinal Survey of Youth 1979 survey are examined. Outcomes include macrosomia,...

This paper provides new empirical evidence on the contribution of selective migration to the health advantage of immigrants upon arrival to the new destination (i.e. the Healthy Immigrant Effect). It analyses a very interesting episode in international migration, namely the exodus of Ecuadorians...
