Rice Technology, Farmer Rationality, and Agricultural Policy in Egypt
通过估计成本函数，发现埃及稻农对价格变化反应理性，并分析了减少化肥贸易限制对化肥价格和用量的影响，以及机械补贴对缓解劳动力短缺的无效性。
Abstract Estimates of a homothetic translog cost function show that Egyptian rice farmers are economically rational and responsive to input price changes. Own‐price and cross‐price elasticities of input demand based on the cost function estimates provide insight into policies currently being pursued or considered by the Egyptian government. The analysis indicates a reduction in fertilizer trade restrictions could substantially reduce fertilizer prices and increase fertilizer use. Labor and mechanical power are not strong substitutes, indicating that subsidization of machinery is not an appropriate policy to reduce agricultural labor shortages.
