The distributional impact of climate change

Abstract

Poorer, hotter countries are more vulnerable to climate change and will experience more negative impacts. The pattern of vulnerability between countries is used to impute impacts for income deciles within countries, for administrative regions, and for grid cells. Almost three-quarters of people will face worse impacts than their country average. Between-country variation is larger than within-country variation for income deciles and regions, and about as large for grid cells. I here revisit earlier estimates of the economic impact of climate change and extend the analysis to impute the distribution of impacts within countries.
