Abstract
This study exploits a natural experiment in Scotland where the legal blood alcohol content (BAC) limit was reduced from 0.8 to 0.5 mg per 100 ml of blood while staying constant in all other parts of the United Kingdom. Using a difference-in-differences design, we find that this change in the BAC level had no impact on either traffic accident or fatality rates.
摘要
本研究利用了苏格兰的一项自然实验，该实验将法定血液酒精含量（BAC）上限从每 100 毫升血液 0.8 毫克降低到 0.5 毫克，而英国其他地区的 BAC 上限保持不变。使用双重差分设计，我们发现 BAC 水平的这一变化对交通事故或死亡率没有影响。
