《斯特恩评论》报告称，碳的社会成本超过300美元/吨，呼吁制定雄心勃勃的气候政策。在此，我们对这一结果对两个关键参数进行了系统的敏感性分析：纯时间偏好率和风险厌恶率。我们表明，碳的社会成本在0到120000美元/tC之间。然而，如果我们将这两个参数限制在与观察到的行为相匹配的范围内，预期的社会碳成本为60美元/tC。如果我们对世界各地的收入差异修正这一估计，碳的社会成本将上升到200美元/吨以上。
The Stern Review reported a social cost of carbon of over $300/tC, calling for ambitious climate policy. We here conduct a systematic sensitivity analysis of this result on two crucial parameters: the rate of pure time preference, and the rate of risk aversion. We show that the social cost of carbon lies anywhere in between 0 and $120000/tC. However, if we restrict these two parameters to matching observed behaviour, an expected social cost of carbon of $60/tC results. If we correct this estimate for income differences across the world, the social cost of carbon rises to over $200/tC.
