|October 2018||An Economist’s Guide to Climate Change Science|
with Solomon Hsiang: w25189
Climate change management is a global challenge that requires social science as much as it requires natural science. We provide a brief introduction to the physical science of climate change, written to provide essential background for economists and other social scientists. We also highlight some key areas in which economists—including those studying macroeconomics, political economy, and development—are in a unique position to help climate science advance.
|August 2018||Evaluating the Economic Cost of Coastal Flooding|
with Klaus Desmet, Scott A. Kulp, Dávid Krisztián Nagy, Michael Oppenheimer, Esteban Rossi-Hansberg, Benjamin H. Strauss: w24918
Sea-level rise and ensuing permanent coastal inundation will cause spatial shifts in population and economic activity over the next 200 years. Using a highly spatially disaggregated, dynamic model of the world economy that accounts for the dynamics of migration, trade, and innovation, this paper estimates the consequences of probabilistic projections of local sea-level changes under different emissions scenarios. Under an intermediate greenhouse gas concentration trajectory, permanent flooding is projected to reduce global real GDP by an average of 0.19% in present value terms, with welfare declining by 0.24% as people move to places with less attractive amenities. By the year 2200 a projected 1.46% of world population will be displaced. Losses in many coastal localities are more than an o...
