This paper aims at obtaining the effects of teenage motherhood on later educational and labour market achievement of the mothers. Constructing a pseudo-panel from the Brazilian Household Surveys (PNAD 1992-2004) and using Health Ministry data (DATASUS 1981-1992), this paper proposes the use of past records on abortion rates in the state of birth as identifying instrument associated with teenage women reproduction. The resulting IV estimates prove negative but insignificant effects, after accounting for state of birth, cohort and a rich set of control variables. Nonetheless, we do not find significant differences between the IV and the negative and significant OLS estimates. The findings of this paper therefore do not reject the perception that anticipated motherhood is detrimental of the high school completion, completed schooling, and labour force participation at women subsequent ages.
