摘要

摘要本研究以撒哈拉以南非洲5个国家为研究对象,采用参数和非参数估计方法确定稻米品质属性的享乐价格,并采用部分均衡模型确定稻米品质改善投资的收益。结果表明,消费者愿意为在城市市场销售的稻米支付价格溢价,包括头米、细粒米、峰值粘度米、半熟米和大米。然而,直链淀粉含量、含杂质大米和进口大米的价格却大幅下降。通过降低直链淀粉含量进行质量改善投资,净福利收益为47.86,内部收益率为90%。

Pricing Rice Quality Attributes and Returns to Quality Upgrading in Sub-Saharan Africa
Abstract The study applies parametric and nonparametric estimation methods to determine hedonic prices of rice quality attributes, and a partial equilibrium model to determine the payoff to investing in quality improvement in five countries in Sub-Saharan Africa. Results indicate that consumers are willing to pay price premiums for head rice, slender grains, peak viscosity, parboiled rice, and rice sold in urban markets. However, they strongly discount amylose content, rice with impurities and imported rice. Investing in quality improvement through amylose content reduction leads to net welfare gains with a benefit-cost ratio of 47.86 and internal rate of return of 90%.
