The effect of alcohol sales restrictions on alcohol poisoning mortality: Evidence from Russia
利用俄罗斯地区差异作为自然实验，研究发现限制酒精销售时间反而导致酒精中毒死亡率上升，因为人们转向更毒的酒精替代品。
This paper examines the tough anti-alcohol legislation recently introduced in Russia, which due to regional variation allows it to be used as a natural experiment. The effect of the restricted trading hours on alcoholic poisoning mortality is estimated. To establish a causal link, difference-in-differences and synthetic controls are used. The main conclusion is that the sales restrictions lead to higher alcohol poisoning mortality, which implies that more toxic alcohol surrogates serve as substitutes for commercially available alcohol.
