The Economic Lesson
Pigovian taxes, named after economist Arthur Pigou (1877-1959), are based on the idea that undesirable behavior creates a cost for society. Therefore, a tax is essentially a “payback” that offsets the cost and/or minimizes the behavior because it becomes more expensive. The negative result is also called a negative externality.
