本文分析了对外开放的发展中小国利用仓储和贸易政策以实现食品价格稳定。运用包含风险规避型消费者和不完全市场的理性预期仓储模型,最优稳定政策得以界定。在不进行公共干预的情况下,价格的变化取决于国内生产冲击和国际价格。就政策本身而言,我们发现最优仓储政策对消费者造成损害,因为它的稳定收益外溢到了国际市场。相比之下,仓储和贸易政策的最优组合则能够有效稳定国内食品价格。然而, This article analyzes the opening up of small and medium-sized developing countries to use warehousing and trade policies to achieve food price stability.
