Correction to: De Economist 10.1007/s10645-021-09389-y
In the original publication of the article, the data in Figs. 1 and 2 were published incorrectly. The corrected figures are given in below.
Fig. 1.
Demand for online groceries, measured by number of unique visitors
Fig. 2.
Demand for online groceries, measured by average sales per order
Additionally, in the online version there is an appendix that contains Table 3, which is not in pdf format. Rows 1 and 2 therein (“Unique visitors” and “Sales per order”) should be removed. The original article has been corrected.
