These studies indicate that privatization increases the
sales of privatized beverages but has little effect on the
sales of non privatized alcoholic beverages. The one
study that evaluated the reintroduction of government
monopoly control of sale of an alcoholic beverage
(medium-strength beer) found that remonopolization
led to a significant decrease in motor-vehicle crashes
for most age groups and a significant decrease among
youth for several, but not all, alcohol-related harms.
