The services and incentives provided by social policies significantly
affect teenage pregnancy and child-bearing outcomes. Policies that off
er tangible family-planning services and that improve access to and af
fordability of abortion have stronger, more consistent effects on teen
age sexual behavior than do those that focus on changing personal atti
tudes and values. Higher welfare benefits may provide an incentive for
pregnant teenagers to forgo marriage. Policies that improve teenagers
' educational and earnings opportunities appear to contribute indirect
ly toward reducing teenage pregnancy and childbearing. This effect lik
ely arises because better economic prospects lead teenagers to believe
that they have something to lose by becoming parents, thus motivating
them to defer having children.
