Temporary trade shocks and regional development: evidence from the closure of Abidjan port
利用科特迪瓦内战导致邻国无法使用阿比让港这一自然实验，研究发现临时贸易限制对经济活动产生负面影响，并引发反向结构变化，且影响具有持续性。
Abstract Can temporary trade restrictions reshape regional development? To analyze this, we exploit the Cote d’Ivoire civil war that disrupted access to Abidjan port for neighboring land-locked countries: Mali and Burkina Faso. Estimates from a difference-in-difference design suggest negative effects on economic activity and a reverse structural change in the treatment communes. We find evidence of persistence through irreversible investment in built-up areas and divergence in the growth of nightlights. Treatment communes at the intermediate distance from the nearest city experienced stronger adverse impacts, driven partly by a relocation to the communes close to other ports.
