TEENAGE FERTILITY AND HIGH-SCHOOL COMPLETION
利用1979-85年美国青年纵向调查数据，用双变量probit模型分析青少年生育对高中毕业的影响，发现生育是内生变量，忽略内生性会高估其负面效应。
This paper uses 1979-85 data on women from the National Longitudinal Survey of Youth to examine the economic, 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 overestimate of the schooling consequences of early childbearing.
