Trade, value chains, and rent distribution with foreign exchange controls: Coffee exports in Ethiopia
研究了埃塞俄比亚外汇管制如何影响咖啡出口价值链中的定价与租金分配，发现出口商为获取稀缺外汇而高价收购咖啡，最终使咖啡农意外受益。
Abstract 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.
