Abstrakt: How often do online retailers change prices? Are there any differences in their price
rigity? I collected and analysed more than 4 million daily prices of online grocery
retailers from Czechia during the unprecedented period between January 2020 and
April 2021. There are substantial differences in pricing among the four retailers. The
mean number of all price changes ranges among the retailers between 3.10 and
almost 11 per year. Most of the price changes are temporary. Retailers change prices
permanently on average between 0.68 to 4.04 times per year. The differences in
pricing persist even after the disaggregation of the products into individual
categories and even in the estimation of the within-between model of the
probability of price change. An in-depth analysis of temporary price adjustments is
crucial to robustly assess pricing and price rigidity. It is likely to explain part of the
discrepancy in pricing found across the retailers.
