Wet Laws, Drinking Establishments and Violent Crime
利用堪萨斯州1977-2011年县级数据，以酒类销售合法化为工具变量，发现饮酒场所数量增加10%会导致暴力犯罪上升3-5%，财产犯罪也有较小幅度的增加。
Drawing on county‐level data from Kansas for the period 1977–2011, we examine whether plausibly exogenous increases in the number of establishments licensed to sell alcohol by the drink are related to violent crime. During this period, 86 out of 105 counties in Kansas voted to legalise the sale of alcohol to the general public for on‐premises consumption. Using legalisation as an instrument, we show that a 10% increase in drinking establishments is associated with a 3–5% increase in violent crime. The estimated relationship between drinking establishments and property crime is also positive, although smaller in magnitude.
