Abortion as Insurance

This paper views abortion access as an insurance policy that protects women from unwanted pregnancies. Within this framework, we present a theoretical model where greater access provides value in the form of insurance against unwanted births and also reduces the incentive to avoid pregnancy. This model predicts that legalized abortion should lead to a reduction in the likelihood of giving birth. It also predicts that if abortion access becomes relatively inexpensive (including both monetary and psychic costs), then pregnancies would rise and births would remain unchanged or may even rise as well. We review the evidence on the impact of changes in abortion policy mainly from the United States and find support for both predictions. Then we test these hypotheses using recent changes in abortion policy in several Eastern European countries. We find that countries which changed from very restrictive to liberal abortion laws experienced a large reduction in births, highlighting the insurance value. Changes from modest restrictions to abortion available upon request, however, led to no such change in births despite large increases in abortions, indicating that pregnancies rose as well. These findings are consistent with the incentive effect implications of our model.
