The effects of post-Dobbs abortion bans on fertility
利用2023年上半年新发布的临时出生数据，采用预注册的合成双重差分法，估计美国近完全堕胎禁令对生育率的影响，发现禁令州出生率平均上升2.3%。
The U.S. Supreme Court decision in Dobbs v. Jackson Women’s Health Organization sparked the most profound transformation of the landscape of abortion access in 50 years. We provide the first estimates of the effects of near-total abortion bans on fertility using a pre-registered synthetic difference-in-differences design applied to newly released provisional natality data for the first half of 2023. The results indicate that states with abortion bans experienced an average increase in births of 2.3 percent relative to if no bans had been enforced.
