Economists love taxes. At least, we love the right kind of taxes, those that discourage bad actions and encourage good ones. Tobacco taxes, for example, make smoking a habit that hurts your pocketbook as well as your lungs. Evidence suggests that teens smoke less just because it has become so darned expensive. Hear, hear!
A “carbon tax” is one of the good taxes. If you accept any one of the following propositions – a)human activity has precipitated global warming, b)human activity hasn’t done so in the past, but it might in the future and this would be a bad thing, OR c) fossil fuel imports put money in the pockets of unstable nations and the world would be a safer place if we used less – then you should support a carbon tax. (If you don’t accept any of the above conditions, it is time to turn the page.)
