Drink and drive? Understanding the dynamics of youth risk‐taking
利用新西兰将最低合法饮酒年龄从20岁降至18岁的政策变化，研究青少年风险行为的动态变化，发现降低饮酒年龄并未增加青少年酒驾事故，甚至短期减少了风险驾驶。
We exploit a reduction in the minimum legal drinking age (MLDA) in New Zealand from 20 to 18 to study the dynamics of youth risk-taking. Using the universe of road accidents over 15 years and an event history approach, we find no evidence that lowering the drinking age increased alcohol-related accidents among teens. Complementary results of a cohort analysis suggest that reducing the drinking age even led to a short-term decline in risky driving among youths directly affected by the MLDA change but had no longer-run impacts on youth risky driving and drinking behaviors.
