国内冲突引发的贸易转移的持久性

The persistence of trade relocation from civil conflict
Journal of Development Economics · 2024 · Tobias Korn、Henry Stemmler

中文摘要

本文考察国内冲突对双边贸易流量的持久影响,以及这些影响对经济复苏的后续意义。我们采用一种基于国际贸易结构引力模型的新型估计方法,表明进口国会将贸易偏好从卷入国内冲突的出口国转向其他国家。即使冲突已经解决,这一效应仍会持续,因为各国通过特惠贸易协定降低与替代贸易伙伴的双边贸易成本,从而巩固其贸易转移决策。值得注意的是,这种持久的贸易转移在制造业部门更为明显,而在燃料部门并未出现。我们的研究结果凸显了支持性贸易政策的重要性:此类政策是帮助各国从政治暴力事件中复苏的有效工具。此外,我们的估计方法可加以调整,用于考察其他单边冲击(如自然灾害)的影响,或分析包括迁移在内的各类双边因变量。

Abstract

This paper examines the lasting impact of civil conflicts on bilateral trade flows and the subsequent implications for economic recovery. Utilizing a novel estimation approach based on the structural gravity model of international trade , we demonstrate that importers shift their trade preferences away from exporters involved in civil conflicts. This effect persists even after the conflict has been resolved, as countries solidify their relocation decisions by reducing bilateral trade costs with alternative trading partners through Preferential Trade Agreements. Notably, the persistent trade relocation is more pronounced in the manufacturing sector , while it does not occur in the fuels sector. Our findings underscore the significance of supportive trade policies as effective tools for assisting nations in recovering from episodes of political violence. Furthermore, our estimation approach can be adapted to investigate the impacts of other unilateral shocks, such as natural disasters, or to analyze various bilateral dependent variables, including migration.
