The benefits of Pigovian taxes
Heads, You Win. Tails, You Win, Too.
By ROBERT H. FRANK, NYT
NO one enjoys paying taxes — and no politician relishes raising them. Yet some taxes actually make us better off, even apart from the revenue they provide for public services.
Taxes on activities with harmful side effects are a case in point. Strongly favored even by many conservative Republican economists, these levies are known as Pigovian taxes, after the British economist Arthur C. Pigou, who advocated them in his 1920 book, “The Economics of Welfare.” In today’s deeply polarized political climate, they offer one of the few realistic hopes for progress.
To see how Pigovian taxes work, consider a driver checking out the offerings at his local auto dealership. He is trying to decide between two vehicles, one weighing 6,000 pounds and the other, 4,000 pounds. After comparing sticker prices, mileage estimates and other features, he views the choice as roughly a tossup. But because he has a slight preference for the larger vehicle, he buys it. His decision, however, could be viewed as a bad choice for society as a whole, because of the side effects. The laws of physics tell us that heavier vehicles tend to cause more damage in crashes. They also spew more emissions into the air and cause more wear and tear on roads.
By providing an incentive to take those external costs into account, taxing vehicles by weight would make the total economic pie larger. Those who don’t really need heavier vehicles could buy lighter ones and pay less tax. Others could pay the extra tax as fair compensation for their heavier vehicles’ negative side effects.

Am I the only one who finds it interesting the first three letters of this particular 'taxes are good for anything that ails ya' malarkey form the commonly used term to describe those who over-consume?
