Causal Analysis of Policy Effects on Fertility

This chapter reviews the literature on the causal effects of policies on fertility. It focuses on evidence from experiments and quasi-experiments in low fertility contexts, including studies from Europe, Northern America, Oceania, and Asia. Making no a priori restrictions on policy type, the review encompasses evaluations of parental leave, childcare, health insurance, and financial incentives such as child transfers. Childcare expansions increase completed fertility. Financial incentives had positive effects on fertility across contexts, both in the short and long run. Expansions of parental leave rights in Central Europe, and introduction of parental leave in the USA, also had positive effects. Distributional effects of these policies are very different, with parental leave compensation benefiting high-earning couples, while expansions of childcare programs have potential to reduce social inequalities. Publicly funded assisted reproduction can increase fertility for women over the age of 35.
