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...

The price system, the adjustment of prices to changes in market conditions, is the primary mechanism by which markets function and by which the three most basic questions get answered: what to produce, how much to produce and for whom to produce. To the behaviour of price and price system,...

The literature on costs of price adjustment has long argued that changing prices is a complex and costly process. In fact, some authors have suggested that we should think of firms' price-setting activities as "producing" prices, similar to the way firms use production processes to produce goods...

We report the results of surveys we conducted in the US and Israel in 2020, a time when many prices increased following the spread of the COVID-19 pandemic. To assess respondents' perceptions of price increases, we focus on goods whose prices have increased during the pandemic, including some...

We study Israel's "price rounding regulation" of January 1, 2014, which outlawed non-0-ending prices, forcing retailers to round 9-ending prices, which in many stores comprised 60%+ of all prices. The regulation's goals were to eliminate (1) the rounding tax-the extra amount consumers paid...

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...
