本文利用21岁的最低法律的饮酒年龄所造成的不连续性来估计酒精供应增加对大麻使用的因果影响。我们发现，大麻的消费量在21岁时急剧下降，而酒精的消费量增加，这表明大麻和酒精是替代品。我们进一步发现，酒精和大麻之间的替代效应对女性比男性更强。我们的研究结果表明，旨在限制酒精使用的政策产生了增加大麻使用的意外后果。(C)2012爱思唯尔有限公司版权所有。
This paper exploits the discontinuity created by the minimum legal drinking age of 21 years to estimate the causal effect of increased alcohol availability on marijuana use. We find that consumption of marijuana decreases sharply at age 21, while consumption of alcohol increases, suggesting that marijuana and alcohol are substitutes. We further find that the substitution effect between alcohol and marijuana is stronger for women than for men. Our results suggest that policies designed to limit alcohol use have the unintended consequence of increasing marijuana use. (C) 2012 Elsevier B.V. All rights reserved.
