作者衡量了气候对土地价格的经济影响。他们利用美国近3,000个县的气候、农田价格以及其他经济和地球物理数据的横截面数据，发现除秋季外，所有季节的高温都会降低平均农场价值，而秋季以外的降水量会增加农场价值。将该模型应用于全球变暖情景显示，全球变暖对美国农业的估计影响明显低于传统的生产函数方法，并且在一种情况下，表明即使没有二氧化碳施肥，全球变暖也可能对农业产生经济效益。版权所有1994年美国经济协会。
The authors measure the economic impact of climate on land prices. Using cross-sectional data on climate, farmland prices, and other economic and geophysical data for almost 3,000 counties in the United States, they find that higher temperatures in all seasons except autumn reduce average farm values, while more precipitation outside of autumn increases farm values. Applying the model to a global-warming scenario shows a significantly lower estimated impact of global warming on U.S. agriculture than the traditional production-function approach and, in one case, suggests that, even without carbon dioxide fertilization, global warming may have economic benefits for agriculture.
