Exchange rate policies can have important implications on incentives for export agriculture. However, their effects are often not well understood. We study the issue of foreign exchange controls and pricing in the value chain for Ethiopia's coffee—its most important export crop. Relying on unique pricing and cost data, we find that coffee exporters are willing to incur losses during exporting by offering high prices for coffee locally in order to access scarce foreign exchange. We further find that the consequent high wholesale prices for coffee are transmitted to producers, so that coffee farmers are unintended beneficiaries of this rent.

通过外汇管制进行贸易，价值链和租金分配：埃塞俄比亚的咖啡出口

汇率政策可能对鼓励出口农业的措施产生重要影响。但是，它们的作用通常不是很清楚。我们研究了埃塞俄比亚咖啡（其最重要的出口作物）价值链中的外汇管制和定价问题。依靠独特的定价和成本数据，我们发现咖啡出口商愿意通过在本地提供高价格的咖啡以获取稀少的外汇而在出口过程中蒙受损失。我们进一步发现，随之而来的咖啡批发价高昂被转嫁给了生产者，因此咖啡农成为了这笔租金的意外受益者。
