Technology as an Agricultural Pollution Control Policy
通过两要素模型和美国玉米市场模拟,分析技术进步对化肥和农药使用的影响,发现资本和土地增强型创新可能反而增加化学品用量,对政策制定者评估技术减排效果有参考价值。
Abstract In this paper we consider the market‐level impacts of factor‐augmenting innovations designed to reduce the use of fertilizers and pesticides, first within the context of a simple two‐factor model, and then through a simulation model of the U.S. corn market. In both models, the impacts depend on the output demand elasticity and input substitution elasticities. The principal conclusion of the simulation analysis is that the potential for new techniques to reduce the use of agricultural chemicals is limited. Capital‐augmenting innovations would actually raise fertilizer and pesticide usage. Land‐augmenting innovations would also tend to increase pesticide usage.
