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.
