Rice Trade Liberalization and Implications for U.S. Policy
建立了一个将大米视为差异化产品的美国大米模型，分析乌拉圭回合贸易自由化对不同大米品种的影响，发现更灵活的政策可在贸易自由化后提高农民收入并降低政府支出。
Abstract The U.S. government's rice program treats rice as a homogeneous commodity, even though rice's two primary subspecies, indica and japonica, are differentiated commodities in world markets. Trade liberalization under the Uruguay round of GATT is expected to increase demand for japonica more than for indica. We develop a U.S. rice model which treats rice as a differentiated product. U.S. government programs are modeled and trade liberalization scenarios are analyzed under alternative policies. Compared to the current policy, a more flexible U.S. policy that treats rice as a differentiated commodity could result in both higher farm incomes and lower government expenditures after trade liberalization.
