摘要翻译:
我们建立了一个新的气候与经济系统的随机动态区域综合评估模型(IAM),该模型包含了许多重要的气候科学要素,而这些要素是大多数IAMS中所缺少的。这些要素是从赤道到两极的空间热量输送、海平面上升、永久冻土解冻和引爆点。研究了在风险和递归效用条件下,两个地区(北半球和南半球)合作和不合作下的最优策略。提出了一种新的求解反馈纳什均衡的通用算法。我们的结果表明,当忽略气候科学的因素时,最优区域碳税和适应等重要的政策变量可能会严重偏差。我们还发现,各地区在反馈纳什均衡下的碳税显著小于在社会规划者问题下的碳税,北方的碳税高于南北向。

英文摘要:
We build a novel stochastic dynamic regional integrated assessment model (IAM) of the climate and economic system including a number of important climate science elements that are missing in most IAMs. These elements are spatial heat transport from the Equator to the Poles, sea level rise, permafrost thaw and tipping points. We study optimal policies under cooperation and noncooperation between two regions (the North and the Tropic-South) in the face of risks and recursive utility. We introduce a new general computational algorithm to find feedback Nash equilibrium. Our results suggest that when the elements of climate science are ignored, important policy variables such as the optimal regional carbon tax and adaptation could be seriously biased. We also find the regional carbon tax is significantly smaller in the feedback Nash equilibrium than in the social planner's problem in each region, and the North has higher carbon taxes than the Tropic-South.
