市场整合与暴力对贸易网络的影响：来自尼日利亚的证据
Market integration and the impact of violence on trade networks: Evidence from Nigeria
摘要
Market integration is critical for food security in developing economies facing socio-political instability. Using weekly price data from ninety-seven Nigerian markets, this study investigates how violent conflict influences price dynamics between market pairs. Results reveal that frequent violent events have limited short-term effects on price transmission, and changes in conflict intensity do not significantly disrupt price adjustments. Markets with stronger trade connections demonstrate greater resilience by leveraging alternative trade routes. These findings highlight the role of market connectivity in maintaining trade efficiency, suggesting that policies that enhance market networks can strengthen resilience and improve food security.
中文摘要
市场整合对于面临社会政治动荡的发展中经济体的粮食安全至关重要。本研究利用尼日利亚97个市场的周度价格数据，考察暴力冲突如何影响市场对之间的价格动态。结果显示，频繁的暴力事件对价格传导的短期影响有限，冲突强度的变化并未显著干扰价格调整。贸易联系较强的市场通过利用替代贸易路线展现出更强的韧性。这些发现凸显了市场连通性在维持贸易效率中的作用，表明增强市场网络的政策能够强化韧性并改善粮食安全。
