Health effects of a ban on late‐night alcohol sales
研究德国禁止晚上10点到早上5点销售酒类的影响，发现该禁令未减少酒驾事故，但使青少年因酒精中毒住院减少约9%，就诊减少约18%。
This paper studies the impact of a ban on late-night off-premise alcohol sales between 10 p.m. and 5 a.m. in Germany. We use three large administrative data sets: (i) German diagnosis related groups-Statistik, (ii) data from a large social health insurance, and (iii) Road Traffic Accident Statistics. Applying difference-in-differences and synthetic-control-group methods, we find that the ban had no effects on alcohol-related road casualties, but significantly reduced alcohol-related hospitalizations (doctor visits) among young people by around 9 (18) percent. The decrease is driven by fewer hospitalizations due to acute alcohol intoxication during the night-when the ban is in place-but not during the day.
