The COVID-19 pandemic has curtailed lives and livelihoods, leading to price spikes for some foods and declines for others. We compare monthly retail food prices in up to 181 countries from January 2019 to June 2021, test for differences over time and find that average prices rose significantly, especially for more nutritious food groups in countries with higher COVID-19 case counts. Analysis of retail prices by food group complements data on farm commodity prices and overall consumer price indexes, helping to guide policy for resilience and response to shocks.

在 COVID-19 病例数较高的国家，营养食品的零售价格上涨更多

COVID-19 大流行削弱了生命和生计，导致某些食品价格飙升，而另一些食品价格下跌。我们比较了 2019 年 1 月至 2021 年 6 月期间多达 181 个国家/地区的月度食品零售价格，检验随时间变化的差异，发现平均价格显着上涨，尤其是对于 COVID-19 病例数较高的国家中更有营养的食品类别。按食品类别对零售价格进行的分析补充了农产品价格和总体消费者价格指数的数据，有助于指导弹性政策和应对冲击。
