Fat Tails and the Social Cost of Carbon. Weitzman, M. L. American Economic Review, 104(5):544–546, May, 2014.
Fat Tails and the Social Cost of Carbon [link]Paper  doi  abstract   bibtex   
At high enough greenhouse gas concentrations, climate change might conceivably cause catastrophic damages with small but non-negligible probabilities. If the bad tail of climate damages is sufficiently fat, and if the coefficient of relative risk aversion is greater than one, the catastrophe-reducing insurance aspect of mitigation investments could in theory have a strong influence on raising the social cost of carbon. In this paper I exposit the influence of fat tails on climate change economics in a simple stark formulation focused on the social cost of carbon. I then attempt to place the basic underlying issues within a balanced perspective.
