The impact of sex education mandates on teenage pregnancy: International evidence
利用跨国数据，研究了发达国家性教育法律对青少年生育率的影响，发现强制令与更高生育率相关，但法律变化无法解释近年生育率下降。
To date most studies of the impact of school-based sex education have focused either on specific, local interventions or experiences at a national level. In this paper, we use a new cross-country dataset to explore the extent to which laws on sex education affect teenage pregnancy rates in developed countries. We find some evidence that laws mandating sex education in schools are associated with higher rates of teenage fertility. Parental opt out laws may minimise adverse effects of sex education mandates for younger teens. The estimated effects of mandatory sex education are robust to some but not all of our specifications designed to tease out causality. Taken together, changes in national laws relating to sexual health are unable to explain the significant declines in teenage pregnancy rates, which have been observed in many developed countries in recent years.
