Some Research Challenges in the Economics of Climate Change

The paper reviews progress in understanding the economics of climate change with an emphasis on identifying promising advances that are both significant and nonmarginal, as well as areas in which there are key gaps in our knowledge. We highlight several important areas in which important policy-relevant research questions remain: improving estimates of climate damage used for determining the social cost of carbon, refining integrated assessment models, and designing better climate policies. As the world moves to understand and implement country emissions reduction pledges in the context of the UNFCCC, understanding the economics of the problem will become even more important. The hope is that the paper is not only informative for existing economists already working in climate change economics, but that it also serves as an inspiration for economists in other areas, or even those in other disciplines, on ways in which to contribute to solving the problem at hand.
