At the centre of the multi-dimensional impact of the COVID-19 pandemic, the shortage of medical supplies in countries with weaker healthcare systems significantly reduced the effectiveness of national and international public health interventions. Using a database of test-kit trade flows and barriers, we estimate the price responsiveness of test-kit demand in a global sample of countries. These estimates allow us to investigate the degree to which import tariffs by leading producers could result in a disruption in global supply chains, price increases, and welfare loss. Simulation experiments indicate that the combination of rising demand for test kits and import dependence magnifies the impact of trade barriers on consumer welfare and this impact is more profound for developing countries.
在新冠疫情的多维度影响中，医疗体系较弱国家的医疗物资短缺显著降低了国家和国际公共卫生干预措施的有效性。利用一个检测试剂盒贸易流动与壁垒的数据库，我们估算了全球样本国家中检测试剂盒需求的价格反应性。这些估算使我们能够研究主要生产国的进口关税在多大程度上可能导致全球供应链中断、价格上涨以及福利损失。模拟实验表明，检测试剂盒需求上升与进口依赖相结合，放大了贸易壁垒对消费者福利的影响，而且这种影响对发展中国家更为深远。
