The Economist


Robin Hanson


With a cap-and-trade regime, where annual emissions are strictly capped, variation in these costs implies significant price volatility. It also forces the market to cut emissions at times when emission reduction costs are high. A carbon tax, on the other hand, would allow firms to cut emissions most when doing so is cheapest. This is a strong argument in favour of the overall efficiency advantages of a carbon tax. But there's more to the story than that. ...

Disagree Does Cap and Trade beat carbon tax for reducing emissions? Disagree

Among all the policy arguments I accept, [skepticism about] war seems among the most solid. And among all the things policy can get wrong, war seems among the worst. So for me, war policy tends to trump other considerations. ... I voted against Bush in '04, and I'll vote against Obama in '12, because they both started wars without meeting the high standards I hold for justifiably starting a war.
