We thank three anonymous referees for thoughtful comments and suggestions which we found very constructive and helpful. We are particularly grateful to the editor, Al Klevorick, for his advice and painstaking guidance through the multiple revision process. We thank Robert Barsky, Susanto Basu,...

Using data from three sources (a laboratory experiment, a field study, and a large US supermarket chain), we document a surprising asymmetric behavior of 9-ending prices: they are more rigid upward, but not downward, in comparison to non 9-ending prices. The data from the lab experiment and the...

We use micro level retail price data from convenience stores to study the link between 0-ending price points and price rigidity during a period of a runaway inflation, when the annual inflation rate was in the range of 60%-430%. Surprisingly, we find that 0-ending prices are less likely to...

We study different notions of sale and regular prices, and their variability with store pricing-formats. We use data from three large stores with different pricing-formats (EDLP/Hi-Lo/Hybrid) that are located within 1-km radius. Importantly, the data contain both the actual transaction prices...

We take advantage of a natural experiment to document an emergence of a new price ending that has the same effects as 9-endings. In January 2014, the Israeli parliament has passed a law prohibiting the use of non 0-ending prices. We find that one year after 9-ending prices have disappeared,...

Prices that end with 9, also known as psychological price points, are common, comprising about 70% of the retail prices. They are also more rigid than other prices. We take advantage of a natural experiment to document an emergence of a new price ending that has the same effects as 9-endings. In...

We document an asymmetry in the rigidity of 9-ending prices relative to non-9-ending prices. Consumers have difficulty noticing higher prices if they are 9-ending, or noticing price-increases if the new prices are 9-ending, because 9-endings are used as a signal for low prices. Price setters...
