The Minimum Legal Drinking Age and Crime
利用加州逮捕人口普查数据和断点回归设计，发现刚满21岁的人被捕概率比未满21岁者高5.9%，主要源于袭击、酒精相关犯罪和滋扰犯罪，表明限制饮酒年龄能显著减少犯罪。
Abstract We use variation from the minimum legal drinking age to estimate the causal effect of access to alcohol on crime. Using a census of arrests in California and a regression discontinuity design, we find that individuals just over age 21 are 5.9% more likely to be arrested than individuals just under 21. This increase is mostly due to assaults, alcohol-related offenses, and nuisance crimes. These results suggest that policies that restrict access to alcohol have the potential to substantially reduce crime.
