The Economic Impacts of Climate Change: Evidence from Agricultural Profits and Random Fluctuations in Weather

Greenstone, Michael; Deschenes, Olivier - 2006

This paper measures the economic impact of climate change on US agricultural land by estimating the effect of the presumably random year-to-year variation in temperature and precipitation on agricultural profits. Using long-run climate change predictions from the Hadley 2 Model, the preferred...
