9-ending prices are a dominant feature of many retail settings, which according to the existing literature, is because consumers perceive them as being relatively low. Are 9-ending prices really lower than comparable non 9-ending prices? Surprisingly, the empirical evidence on this question is...

9-ending prices, which comprise between 40%–95% of retail prices, are popular because shoppers perceive them as being low. We study whether this belief is justified using scanner price-data with over 98-million observations from a large US grocery-chain. We find that 9-ending prices are higher...

This paper studies the relationship between retail gasoline pricing strategies and potential demand. Utilising detailed data on traffic on the German Autobahn and the special case of Bundesautobahntankstellen, the interaction between demand and price competition is studied, as are the changes in...

This paper analyzes the effects of a merger between a German supermarket chain and a soft discounter on consumer prices. We exploit geographic variation in prices within retail chains and brands and use a difference-in-differences estimator to compare regional markets with a change in market...

I use firm-product-level data for Canadian online retailers to study how product scope (the average number of product categories per firm) evolved from 1999 to 2012. During this period, product scope dropped monotonically from 59 to 5 product categories. Using a theoretical model of...
