This paper follows the estimation approach used by Schulkind and Sandler (2019) to investigate the life outcomes of adolescent mothers who have their first child around the time of high school graduation. By comparing mothers who give birth before finishing high school with those who give birth after, this study aims to replicate the findings of Schulkind and Sandler regarding the impact of teenage childbearing on mothers' long-term outcomes. Both the original study and this replication reveal that teenage childbearing is associated with a decreased likelihood of completing high school, fewer years of overall education, an increased number of children in the household, a higher risk of living in poverty, and no significant impact on labor market outcomes. However, this study differs in finding no measurable effects on the marital status of teenage mothers, and the impact on later life outcomes is smaller compared to those in the replicated paper.
