既然贸易必须跨越国界，那么边境墙在多大程度上影响了贸易流动？我们认为边境墙会减少贸易流量。即使目标只是阻止非法流动，边界墙也会加强“边界效应”，从而也会抑制法律的跨界流动。使用反映经济理论和计量经济学最新发展的贸易引力模型，我们发现，隔离墙的建立与邻国之间法律的贸易流量的减少有关。我们提供了一系列证据，表明这种减少不仅仅是双边关系恶化的结果。我们的研究结果对于理解在经济全球化日益发展的时代，政府如何采取措施维护对其边界的主权控制具有重要意义。
Since trade must cross borders, to what extent do border walls affect trade flows? We argue that border walls can reduce trade flows. Even if the objective is to only stem illicit flows, border walls heighten "border effects" that can also inhibit legal cross-border flows. Using a gravity model of trade that reflects recent developments in both economic theory and econometrics, we find that the creation of a wall is associated with a reduction in legal trade flows between neighboring countries. We provide a battery of evidence that suggests this reduction is not simply a function of worsening bilateral relations. Our findings have implications for understanding how governments have taken measures to assert sovereign control of their borders in an age of increasing economic globalization.
