近日，我院助理教授崔潇濛的独立作者论文“Climate Change and Adaptation in Agriculture: Evidence from US Cropping Patterns”被环境经济学顶级期刊Journal of Environmental Economics and Management接受发表。
Understanding how a changing climate alters regional comparative advantage is crucial for evaluating the economic impacts of climate change. I exploit temporal variation in decades-long averages of weather and estimate crop acreage elasticities with respect to climate change in the United States. I find substantial climate change adaptation through acreage adjustments in US agriculture. Climate change explains about 10-35% of the observed US corn and soybean expansion over the past 30 years, and climate-driven crop substitution has played an important role. The acreage response is heterogeneous across major and minor producing areas and across dryland and irrigated counties.
