摘要

我们对撒哈拉以南非洲地区边境延误造成的宏观经济后果进行了定量分析。由于要素配置不当，以及在生产中使用外国投入品的企业数量过少，进口中间投入品的延迟会降低总产出。我们的模型经济以异质企业为特征，这些企业在使用外国投入品的程度上存在内生差异。我们根据撒哈拉以南非洲的微观数据对模型进行了校准。减少边境延误可使总产出增加高达 9.4%。收益主要来自于经济活动向生产率更高的企业的重新分配。

Input delays, firm dynamics, and misallocation in Sub-Saharan Africa

We quantitatively analyze the macroeconomic consequences of border delays in Sub-Saharan Africa. Delays of imported intermediate inputs lower aggregate output because of factor misallocation and due to an inefficiently low number of firms that uses foreign inputs in production. Our model economy features heterogeneous firms that endogenously differ in the degree to which foreign inputs are used. The model is calibrated to micro-level data from Sub-Saharan Africa. Reducing border delays can increase aggregate output by up to 9.4%. The gains are mainly due to a reallocation of economic activity towards more productive firms.
