I hate presenting “yesterday’s Op-Eds today,” but that’s what happens with I get behind. Monica Prasad made some interesting — and sure to be controversial — claims in yesterday’s New York Times.

What did Denmark do right? There are many elements to its success, but taken together, the insight they provide is that if reducing emissions is the goal, then a carbon tax is a tax you want to impose but never collect.

This is a hard lesson to learn. The very thought of new tax revenue has a way of changing the priorities of the most hard-headed politicians — even Genghis Khan learned to be peaceful, the story goes, when he saw how much more rewarding it was to tax peasants than to kill them. But if we want lower emissions, the goal of a carbon tax is to prompt producers to change their behavior, not to allow them to continue polluting while handing over cash to the government.
