0.001% and counting: Revisiting the price rounding tax

Abstract In 1991 and 2008, Israel abolished the equivalents of 1¢ and 5¢ coins, respectively, effectively eliminating low‐denomination coins and introducing rounding in cash transactions. When totals were rounded up, shoppers incurred a small rounding tax . Using detailed data on the distribution of price endings and basket sizes across supermarkets, drugstores, small groceries, and convenience stores, we estimate that the magnitude of the rounding tax borne by Israeli consumers averaged only 0.001%–0.002% of revenues in the fast‐moving consumer goods markets. These findings have implications for the ongoing debate regarding the desirability and viability of abolishing the 1¢ and 5¢ coins in the US.
