This study investigated the impact of the novel coronavirus disease 2019 (COVID-19) outbreak on prices of maize, sorghum, imported rice and local rice in sub-Saharan Africa (SSA). We estimated dynamic panel data models with controls for macroeconomic setting using general method of moments estimation. The study found that the COVID-19 outbreak led to increases in food prices of the sampled countries. Restrictions on movements or lockdowns in the wake of COVID-19 was associated with an increase in the price of maize only. We also found that exchange rate, inflation and crude oil prices exerted a detrimental effect on food prices. We recommend that governments of SSA countries invest in infrastructure that improves efficiencies in the food supply chain during pandemics. Providing adequate support to industries in the value chain will also improve food availability and food price stability post-COVID-19.
本研究调查了2019年新型冠状病毒病（COVID-19）疫情对撒哈拉以南非洲（SSA）地区玉米、高粱、进口大米和本地大米价格的影响。我们使用广义矩估计法估计了控制宏观经济环境的动态面板数据模型。研究发现，COVID-19疫情导致抽样国家的食品价格上涨。COVID-19疫情后实施的行动限制或封锁仅与玉米价格上涨有关。我们还发现，汇率、通货膨胀和原油价格对食品价格产生了不利影响。我们建议，撒哈拉以南非洲国家政府投资于基础设施建设，以提高疫情期间食品供应链的效率。为价值链中的行业提供充分支持也将改善COVID-19疫情后食品的可获得性和食品价格稳定性。
