Impacts of Liberalizing Trade in the World Rice Market
用多产品二次规划模型分析贸易自由化对世界大米市场的影响，发现所有大米类型的贸易量和价格都会大幅上升，多数出口国和进口国福利显著改善，美国出口收入增加109%。
Abstract A multi‐product quadratic programming model is used to investigate impacts of trade liberalization on the world rice market, recognizing product differentiation and allowing substitution among various rice types and qualities. Model simulations predict a large increase in both trade volumes and prices for all rice types and a significant welfare gain for most rice exporters and importers. Japan, South Korea, Philippines, Taiwan, and Brazil would be the major importers. Trade liberalization would increase total U.S. export revenue by 109%. Movement to free trade by Japan has significant effects on world rice trade and on Japanese rice production.
