Considering the temporary closure of many food-away-from-home establishments, consumer expenditure on groceries during the COVID-19 pandemic has increased. While grocery shopping is an essential activity, not much is known about the dynamic relationship of the COVID-19 pandemic to the behavior of grocery shoppers. With an objective to inform variability in the behavior of grocery shoppers under various scenarios of the COVID-19 pandemic, we conducted an online framed choice experiment to elicit preferences for purchasing methods, time windows, minimum order requirements, and fees. The manipulating factor relates to the trend in the COVID-19 pandemic, where we consider three scenarios: an increasing, decreasing, or constant number of new cases in the past two-week period. Using 32,400 choice decisions from a representative sample of 900 grocery shoppers in the United States, we conclude that the trend in the COVID-19 pandemic causes significant differences in grocery shopping preferences. In situations where COVID-19 is spreading at an increasing rate, consumers are generally less willing to shop inside the grocery store. When COVID-19 is spreading at a decreasing rate, the relative importance of the purchasing method attribute is lower in its entirety. We use our findings to inform recommendations for practitioners and policymakers.

COVID-19 大流行期间的杂货购物偏好

考虑到许多外出就餐场所暂时关闭，COVID-19 大流行期间消费者在杂货上的支出有所增加。虽然杂货店购物是一项必不可少的活动，但人们对 COVID-19 大流行与杂货店购物者行为的动态关系知之甚少。为了了解在 COVID-19 大流行的各种情况下杂货店购物者行为的变化，我们进行了一项在线框架选择实验，以了解对购买方法、时间窗口、最低订单要求和费用的偏好。操纵因素与 COVID-19 大流行的趋势有关，我们考虑了三种情况：过去两周内新病例的数量增加、减少或保持不变。使用 32，来自美国 900 名杂货店购物者的代表性样本的 400 项选择决策，我们得出结论，COVID-19 大流行的趋势导致杂货店购物偏好的显着差异。在 COVID-19 以越来越快的速度传播的情况下，消费者通常不太愿意在杂货店内购物。当 COVID-19 以下降的速度传播时，购买方法属性的相对重要性总体上较低。我们使用我们的发现为从业者和政策制定者提供建议。当 COVID-19 以下降的速度传播时，购买方法属性的相对重要性总体上较低。我们使用我们的发现为从业者和政策制定者提供建议。当 COVID-19 以下降的速度传播时，购买方法属性的相对重要性总体上较低。我们使用我们的发现为从业者和政策制定者提供建议。
