The Roles of Price Points and Menu Costs in Price Rigidity
Macroeconomic models often generate nominal price rigidity via menu costs. This paper provides empirical evidence that treating menu costs as a structural explanation for sticky prices may be spurious. Using scanner data, I note two empirical facts: (1) price points, embodied in nine-ending prices, account for approximately two-thirds of prices; and (2) at the conclusion of sales, post-sale prices return to their pre-sale levels more than three-fourths of the time. I construct a model that nests roles for menu costs and price points and estimate model variants. Excluding the two facts yields ...

The Effects of Price Endings on Price Rigidity: Evidence from VAT Changes
We document a causal role for price endings in generating micro and macro price rigidity. Based on micro price data underlying the consumer price index in Israel, we document that most stores have a favored price ending?a final digit, usually a zero or nine, used by a majority of prices in that store?and that these favored price endings are utilized extensively. Using changes to the VAT rate as exogenous cost shocks that affect prices regardless of ending, we find that the frequency of price adjustment for nonfavored endings increases by twice as much as the frequency of adjustment for ...
