Any price change could be due either to the changeover itself, because of, for example, rounding up to new eye-catching prices or the pass-through of cash changeover costs, or it might reflect a change in other cost factors, like wages or import prices. This implies that any estimation of the cash changeover effect on prices is surrounded by uncertainty.
In order to get some evidence on price changes which might be related to the cash changeover, it is informative to look at the sector level. Indeed, for specific services items, prices have increased more than usual, which could be related to the introduction of the euro.
