Towards a social cost of carbon with national characteristics
利用全球76个国家的时空偏好数据估算碳社会成本,发现北美和西欧的估算值显著高于其他地区,且按人口加权时差异更大。
The majority of estimates of the social cost of carbon use preference parameters calibrated to data for North America and Europe. We here use statistically representative data for attitudes to time and risk across the world. The social cost of carbon is substantially higher in the global north than in the south. The difference is more pronounced if we count people rather than countries. • We estimate the social cost of carbon using calibrated time and risk preferences for 76 countries. • The social cost of carbon preferred by people and scholars based in North America and Western Europe is higher than for people in the rest of the world. • This result is robust to alternative calibrations of the parameters of the Ramsey rule.
