Teen Motherhood • What might make it tough to estimate the impact of having a teen birth on the mother’s future outcomes? • How might one design an empirical strategy in this context?
Teen Motherhood Geronimus and Korenman (1992) Look at difference in outcomes between teen mothers and non-teen mothers after controlling for a variety of characteristics (age, urban residence, race, mother’s education, father’s education, lived in single parent family at 14, number of siblings) --- “selection on observables” Look at difference in outcomes between sisters who are both mothers but one had first child while a teen and other did not.
Teen Motherhood • What might biases be even when comparing sisters?
Teen Motherhood • Hotz, McElroy, and Sanders • What do they do? • What do they have to recognize when using this strategy in this context?
Teen Motherhood (1) Suppose abortions occur early in pregnancy and miscarriages late. Then women who miscarried would be a random sample of all those teens who became pregnant and gave birth (i.e. did not have an abortion). • Compare those who miscarried to those who gave birth, because in absence of random miscarriage, they should have same outcomes on avg. Group of teens who become pregnant No abortion abortion randomness No birth No miscarriage miscarriage Gave birth No birth
Teen Motherhood (2) Alternatively, suppose abortions occur late in pregnancy and miscarriages early. Then women who miscarried would be a random sample of all teens who become pregnant. • Compare those who miscarried to those who gave birth or had an abortion, because in absence of miscarriage should have same outcomes on avg. Group of teens who become pregnant randomness No miscarriage miscarriage No birth No abortion abortion Gave birth No birth
