This paper finds that approximately one-third of the items in the CPI are governed by price regulations that can slow and add noise to the response of prices to changes in cost or demand conditions. Consequently, regulation is a possible partial explanation of sticky prices in the overall rate...

We study the link between price points and price rigidity, using two datasets: weekly scanner data, and Internet data. We find that: 9 is the most frequent ending for the penny, dime, dollar and ten-dollar digits; the most common price changes are those that keep the price endings at 9; 9-ending...

We study the link between price points and price rigidity, using two datasets: weekly scanner data, and Internet data. We find that: “9” is the most frequent ending for the penny, dime, dollar and ten-dollar digits; the most common price changes are those that keep the price endings at...

We study the link between price points and price rigidity, using two datasets containing over 100 million observations. We find that (i) 9 is the most frequently used price-ending for the penny, dime, dollar and ten-dollar digits, (ii) 9-ending prices are between 24%-73% less likely to change in...

We study the link between price points and price rigidity, using two datasets: weekly scanner data, and Internet data. We find that: "9" is the most frequent ending for the penny, dime, dollar and ten-dollar digits; the most common price changes are those that keep the price endings at "9";...

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...

We explore daily patterns of Internet pricing for the two major retailers, Amazon.com and Barnes and Noble.com (BN), using data on 377 books collected over a 449-day period in 2003-2004. We frame this investigation in terms of a key question: How rigid are prices on the Internet? Are there...
