Discounting and the Economic Costs of Altruism in Greenhouse Gas Abatement
通过数值思想实验，研究了温室气体减排中代际利他主义对可持续碳浓度和经济成本的影响，发现高利他主义虽支持可持续性但增加当前福利损失，而将减排视为资本投资替代则可实现帕累托有效且成本更低。
This paper carries out a numerical thought experiment on greenhouse gas abatement. The main results can be summarized as follows: first, a high degree of intergenerational altruism might support 'sustainable' atmospheric carbon concentration, but imposes high welfare losses on current generations; and second, if agents realize that greenhouse policy is an alternative to investing into physical capital, then even without intergenerational altruism a Pareto-efficient internalization of the external effect of climate change will stabilize the atmospheric carbon concentration at ecologically sustainable levels, but at significantly lower economic costs.
