The Transition of Punjab Agriculture: A Choice of Technique Approach
采用技术选择方法，研究印度旁遮普地区现代作物品种的采用率与水平，发现激励措施和准固定投入（如灌溉、化肥、道路）对农业转型至关重要，并估计了长期总供给弹性。
Abstract The introduction of modern crop varieties in Punjab, India, led to rapid income growth. Adoption rate and level of the new varieties is examined using a choice‐of‐technique approach, in which techniques of production are identified by crop variety, season of growth, and method of production. Modeling the dynamic effects of technology, resource availability, and incentives reveals a consistent picture of the transition process. The results show the importance of incentives and availability of quasi‐fixed inputs such as irrigation, fertilizers, and roads. By the late 1970s, the long‐run aggregate supply elasticity was between 1.3–1.5.
