Monthly turnover data are available for industry and the construction sector. The results for the retail trade are also included in the calculation of private consumption.

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.
