This paper presents results of a unique stated choice (SC) experiment to uncover the determinants of grocery shopping channel choice during the first wave of COVID-19 infections, where the most restrictive containment measures were in place. The choice sets were framed under regular and pandemic conditions, allowing for the estimation of pandemic-specific effects for each of the choice attributes. Our results show a significant overall increase of about 13%-points in online grocery shopping under pandemic conditions. Shopping and delivery costs were found to be the major decision drivers in both experimental settings, while the waiting time in front of the grocery store and risk of infection only played an secondary role. The value of delivery time savings (VDTS) decreases from about 10.8 CHF/day in the regular to 7.4 CHF/day in the pandemic case, indicating that respondents show an increased patience when waiting for the delivery of the ordered groceries. However, choice attributes related to the shopping trip, i.e. travel time and cost, do not show any notable effects. The COVID-19 death risk was valued rather low by the respondents and the relatively unrestricted Swiss containment measures are in line with the respondents’ average preferences, as shown by a relatively low value of statistical life (VSL) of about 800,000 CHF.

本文介绍了一个独特的陈述选择 (SC) 实验的结果，以揭示在第一波 COVID-19 感染期间杂货店购物渠道选择的决定因素，当时采取了最严格的遏制措施。选择集是在常规和大流行条件下构建的，允许估计每个选择属性的大流行特定影响。我们的结果显示，在大流行病情况下，在线杂货店购物总体显着增加了约 13%。购物和送货成本被发现是两个实验设置中的主要决策驱动因素，而杂货店前的等待时间和感染风险仅起到次要作用。交货时间节省 (VDTS) 的价值从正常情况下的约 10.8 瑞士法郎/天减少到大流行情况下的 7.4 瑞士法郎/天，表明受访者在等待订购的杂货送货时表现出更大的耐心。然而，与购物旅行相关的选择属性，即旅行时间和成本，并没有显示出任何显着的影响。受访者对 COVID-19 死亡风险的评价相当低，相对不受限制的瑞士遏制措施符合受访者的平均偏好，统计生命值 (VSL) 相对较低，约为 800,000 瑞士法郎。
