This paper combines pre-pandemic face-to-face survey data with follow up phone surveys collected in April-May 2020 to examine the implication of the COVID-19 pandemic on household food security and labor market participation outcomes in Nigeria. To examine these relationships and implications, we exploit spatial variation in exposure to COVID-19 related infections and lockdown measures, along with temporal differences in our outcomes of interest, using a difference-in-difference approach. We find that households exposed to higher COVID-19 case rates or mobility lockdowns experience a significant increase in measures of food insecurity. Examining possible transmission channels for this effect, we find that the spread of the pandemic is associated with significant reductions in labor market participation. For instance, lockdown measures are associated with 6-15 percentage points increase in households' experience of food insecurity. Similarly, lockdown measures are associated with 12 percentage points reduction in the probability of participation in non-farm business activities. These lockdown measures have limited implications on wage-related activities and farming activities. In terms of food security, households relying on non-farm businesses, poorer households, and those living in remote and conflicted-affected zones have experienced relatively larger deteriorations in food security. These findings can help inform immediate and medium-term policy responses, including social protection policies aiming at ameliorating the impacts of the pandemic.
本文将疫情前的面对面调查数据与2020年4月至5月收集的后续电话调查数据相结合,以研究新冠疫情对尼日利亚家庭粮食安全和劳动力市场参与情况的影响。为了研究这些关系和影响,我们利用新冠相关感染暴露和封锁措施的空间差异,以及我们感兴趣的结果的时间差异,采用双重差分法。我们发现,暴露于更高新冠病例率或行动封锁的家庭,粮食不安全程度显著增加。在研究这种影响的可能传播渠道时,我们发现疫情的蔓延与劳动力市场参与率的显著下降有关。例如,封锁措施使家庭粮食不安全经历增加了6至15个百分点。同样,封锁措施使参与非农业商业活动的概率降低了12个百分点。这些封锁措施对与工资相关的活动和农业活动影响有限。在粮食安全方面,依赖非农业商业的家庭、较贫困家庭以及生活在偏远和受冲突影响地区的家庭,粮食安全状况恶化相对较大。这些发现有助于为即时和中期政策应对提供信息,包括旨在减轻疫情影响的社会保护政策。
