Export Liberalization and Household Welfare: The Case of Rice in Vietnam
构建多市场空间均衡模型，分析越南大米出口自由化对区域价格的影响，并结合家庭数据评估福利变化，发现自由化虽推高粮价、加剧区域不平等，但能提高平均实际收入并略微降低贫困发生率。
Abstract Vietnam has rapidly become one of the three largest rice exporters in the world, in spite of a binding export quota. This article uses a multimarket spatial‐equilibrium model to examine the effect of further liberalization on regional rice prices. Household data are then used to calculate the welfare impact of these price changes on different household groups. The results suggest that although rice export liberalization would raise food prices and exacerbate regional inequality, it would also increase average real income and reduce (slightly) the incidence and severity of poverty. We explore several explanations of these apparently paradoxical results.
