Public health afficiandos are well aware that when you raise the cost of something, access is decreased. So raising the price of cigarettes and alcoholic beverages is one way to decrease use/abuse because it decreases access or makes access more difficult.
An article in the Wall Street Journal on July 16th, reports that Diegeo PLC the distributers for Smirnoff's Vodka, Bailey's Irish Cream, and Captain Morgan Rum as well as other brands raised it's prices on some of its products. While Diegeo's revenue went up with the raised prices, the amount sold decreased.
Turns out that prevention science based on the public health model has further evidence that it's hypothesis about the relationship between cost and access is correct.
