Weitzman, Martin2013-10-032011Weitzman, Marin L. 2011. Revisiting Fat-tailed uncertainty in the economics of climate change. Review of Environmental Economics and Policy 5(2): 275-292.1750-68161750-6824http://nrs.harvard.edu/urn-3:HUL.InstRepos:11130443In this article, I revisit some basic issues concerning structural uncertainty and catastrophic climate change. My target audience here are general economists, so this article could also be viewed as a somewhat less technical exposition that supplements my previous work. Using empirical examples, I argue that it is implausible that low-probability, high-negative impact events would not much influence an economic analysis of climate change. I then try to integrate the empirical examples and the theory together into a unified package with a unified message that the possibility of catastrophic climate change needs to be taken seriously.en-USJournal Article2013-10-0310.1093/reep/rer006
