| Abstract: | This paper presents a time‐series regression analysis of price inflation at the time of the euro currency changeover in January 2002. Cross‐equation tests on 12 euro countries and three non‐euro EU countries are used to identify significant price changes around that time. For a small number of product and service categories, positive price changes immediately after the euro changeover suggest the possible existence of menu costs, sellers' rounding up of prices or buyers' temporary rational inattention. However, the lack of evidence for reduced inflation immediately prior to the euro changeover suggests menu costs are not important. |
