Teenage Fertility and High School Completion
利用1979-85年美国青年纵向调查数据，分析青少年生育与高中毕业的因果关系，发现青少年生育是高中毕业的内生决定因素，忽略内生性会高估生育对学业的影响。
This paper uses 1979-85 data on women from the National Longitudinal Survey of Youth to examine the eco-nomic, sociological, and institutional antecedents of adolescent childbearing and high school completion and to analyze the effect of early childbearing on school completion. Fertility and school completion are modeled as dichotomous outcomes, and their determinants are estimated using a bivariate probit specification. The paper finds evidence that adolescent childbearing is an endogenous determinant of high school completion and that failing to account for this endogeneity leads to an over-estimate of the schooling consequences of early childbearing.
