This paper employs the National Longitudinal Survey of Youth in the US to study the birth process. We develop a simultaneous equations model with seven endogenous variables: four birth inputs (maternal smoking, maternal drinking, first trimester prenatal care, and maternal weight gain), three...

This study offers a simultaneous equations model of the birth process with seven endogenous variables: Four birth inputs (maternal smoking, maternal drinking, first trimester prenatal care, and maternal weight gain) and three birth outputs (gestational age, birth length, and birth weight). The...

This study offers a simultaneous equations model of the birth process with seven endogenous variables: four birth inputs [maternal smoking (S), maternal drinking (D), first trimester prenatal care (PC), and maternal weight gain (WG)], and three birth outputs [gestational age (G), birth length...

This study offers a simultaneous equations model of the birth process with seven endogenous variables: Four birth inputs (maternal smoking, maternal drinking, first trimester prenatal care, and maternal weight gain) and three birth outputs (gestational age, birth length, and birth weight). The...

This paper presents a new model of the birth process of Native Americans with seven endogenous variables: four birth inputs maternal smoking (S), drinking (D), prenatal care (PC), and weight gain (WG), and three birth outputs gestational age (G), birth length (BL), and birth weight (BW). The...

We develop a simultaneous equations model with four birth inputs (maternal smoking, maternal drinking, first trimester prenatal care, and maternal weight gain), three birth outputs (gestational age, birth length, and birth weight), and twenty-four exogenous variables, and employ the National...
