Cover: Coins study - Impact assessment of rounding in the retail sector

This study investigates the effects on consumer prices of rounding final total prices or individual prices in the retail sector. The empirical analysis based on around  70,000 sales receipts shows that, when the final total price is rounded commercially to the nearest whole 5 euro cent increment, virtually no effect on the price level can  be expected.
By contrast, if individual prices are subject to commercial rounding or a general rounding up, minimal one-off increases in the price level can be expected. The  ntroduction of a rounding rule for 1 and 2 euro cent coins results in no significant savings for the retail sector.

Interviews carried out as part of this study also show that the retail sector will not implement a rounding rule of its own initiative. The total cost of supplying coins has
risen much less sharply than roll prices, as the latter account for just 10 % to 20 % of total costs.
