Broadly speaking, there are two reasons to tax. There are taxes intended to raise revenue. And there are taxes intended to dissuade a certain behavior, also called “sin taxes.” The classic example of a tax to dissuade behavior is the cigarette tax. It’s broad worldwide and considered quite effective, particularly among cigarette companies. In fact, a researcher from MIT calculated that the 1982-83 rounds of price increases in the U.S. resulted in two million fewer adult smokers and 600,000 fewer teenage smokers.
