This article focuses on the immediate impacts of coronavirus disease 2019 (COVID‐19) on retail prices of dairy products in the United States. Using weekly data from the US Department of Agriculture, Agricultural Marketing Service, we analyze a change in dairy prices coinciding with COVID‐19 restrictions. Using a regression discontinuity design, we find that prices of all dairy products decreased by 8% at the time that stay at home orders and changes in retail activities took place. When focusing on specific dairy categories, we find a varying degree of price declines, but also many prices that did not change. We also analyze store promotional advertisements for dairy products and find the expected decline in the number of store ads. This study has implications for policymakers concerned about the impact of COVID‐19 on retail food prices in the United States. [EconLit citations: Q11; Q18]

COVID-19大流行对乳制品零售价格的影响

本文重点介绍2019年冠状病毒病（COVID-19）对美国乳制品零售价格的直接影响。使用来自美国农业部农业市场服务部的每周数据，我们分析了与COVID-19限制一致的乳制品价格变化。使用回归不连续性设计，我们发现在保持家庭订单和零售活动发生变化时，所有乳制品的价格均下降了8％。当关注特定的乳制品类别时，我们发现价格下降的程度不同，但许多价格没有变化。我们还分析了乳制品的商店促销广告，并发现商店广告数量的预期下降。这项研究对担心COVID-19对美国零售食品价格的影响的决策者有影响。[EconLit引用：Q11；Q18]
