Environmental effects and natural resources depletion associated with agriculture production affect the agriculture response to climate change. Traditional cross-sectional climate response models ignore this requirement. This research estimates the impact of climate on European agriculture using a continental scale Ricardian analysis. We correct farm income by accounting for resources (energy, fertilisers, pesticides, and water) use intensity and calculate the sustainable value for a sample of 9497 specialized field crop farms. Compared with the traditional Ricardian method, the marginal effects of temperature remain positive (but less positive) in Northern countries, while it leads to less damages in Southern countries when net revenue and farms' sustainable values are used as dependent variables. Accounting for the environmental effects and depletion of natural capital improves the ability of the Ricardian method to estimate agriculture climate response functions in the long run.

解释气候变化影响的横断面经济模型中的外部性

与农业生产有关的环境影响和自然资源枯竭影响农业对气候变化的反应。传统的横断面气候响应模型忽略了这一要求。这项研究使用大陆范围的Ricardian分析估算了气候对欧洲农业的影响。我们通过考虑资源(能源,肥料,杀虫剂和水)的使用强度来校正农场收入,并为9497个专业田间作物农场的样本计算可持续价值。与传统的里卡德方法相比,在北方国家,温度的边际效应仍然为正(但不为正),而将净收入和农场的可持续价值用作因变量,则对南方国家的损害较小。
