Over roughly the same time period, the ratio of infant relinquishment to nonmarital births fell.
Only Medoff  explores an analogous question: are states with the highest infant relinquishment rates also the states with the greatest number of enforced abortion restrictions or the states with the least access to abortion?
Compared to data by state of occurrence, which examines the effect of policy on in-state infant relinquishment rates, state-of-residence data provide a better measure of the effect of abortion policy on a woman's pregnancy resolution decision.(8)
All else equal, states with more restrictive abortion laws also have lower ratios and rates of infant relinquishment by 1 to 5 points (a 20% to 30% decrease from the mean).
Controlling for completion of high school the negative coefficient on Percentage Completed College and the Real Hourly Wage [TABULAR DATA FOR TABLE I OMITTED] may be an indication that states with a greater percentage of women who expect to complete (or have completed) college or have a higher value of time are likely to be states with lower rates of infant relinquishment.(17) Conditional on the number of pregnancies, these states may exhibit either higher abortion demand or higher own-demand for children.
The incarceration rate has a positive and significant effect on the infant relinquishment rate.
