本文探讨了由于 COVID-19 导致印度经济停摆而造成的食品供应链中断。我们使用来自最大的在线杂货零售商之一的新颖数据集来研究对产品缺货和价格的影响。我们发现蔬菜、水果和食用油的产品供应量下降了 10%，但对其价格的影响很小。在农场门口，蔬菜和水果的到达量也下降了 20%。然后我们表明供应链中断是今年秋季背后的主要驱动因素。我们计算了零售中心到生产区的距离，发现距离最终销售点较远种植或制造的商品的产品供应量和到达数量下降幅度更大。我们的研究结果表明，在当前的大流行期间，长距离食品供应链受到的打击最严重，给城市消费者和农民带来了福利后果。
This paper looks at the disruption in food supply chains due to COVID-19 induced economic shutdown in India. We use a novel dataset from one of the largest online grocery retailers to look at the impact on product stockouts and prices. We find that product availability falls by 10% for vegetables, fruits, and edible oils, but there is a minimal impact on their prices. On the farm-gate side, it is matched by a 20% fall in quantity arrivals of vegetables and fruits. We then show that supply chain disruption is the main driver behind this fall. We compute the distance to production zones from our retail centers and find that the fall in product availability and quantity arrivals is larger for items that are cultivated or manufactured farther from the final point of sale. Our results show that long-distance food supply chains have been hit the hardest during the current pandemic with welfare consequences for urban consumers and farmers.
