R.A. at Free Exchange:
LAST week, a Twitter conversation broke out among a few economists concerning whether any serious economists opposed a carbon tax. No, concluded the tweeters, but Tyler Cowen begged to differ. Mr Cowen writes that he personally favours a carbon tax but can imagine a number of principled reasons other economists might not.
Why would we expect economists to support a carbon tax? It's very close to the economic ideal. ...The biggest problem with a carbon tax is that America's government seems unable to deliver one. Attitudes may change, however, and near-uniform economist support for the policy (probably) doesn't hurt its odds of eventual passage.
