We investigate the extent to which certain price points occur in Internet-based selling, and theorize about what drives the observed regularities and variations. This research explores theories based on consumer perceptions of price and quality images, and rational inattention to price-endings....

Price rigidity involves prices that do not change with the regularity predicted by standard economic theory, and is of long-standing interest to firms and industries, and relates to the economy as a whole. As information technology (IT) changes the processes by which strategic pricing decisions...

Analyzing a large weekly retail transaction price dataset, we uncover a surprising regularity small price increases occur more frequently than small price decreases for price changes of up to about 10 cents, while there is no such asymmetry for larger price changes. The asymmetry holds for the...
