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大气碳浓度和当代福利的影响，发现高利他主义虽能维持可持续碳浓度但代价高昂，而将温室政策视为资本投资替代方案可在无利他主义时以更低成本实现生态可持续。
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.
