The Euro Changeover and its Effects on Price Transparency and Inflation.

Abstract

Despite the expectations of economists that the euro changeover would have no effect on prices, we show that European consumers perceived the contrary. The data indicate that consumers based their perceptions about inflation on goods that are cheaper and more frequently purchased. We use this insight to develop and estimate a model of imperfect information that explains why these goods were subject to higher price growth after the changeover. The data indicate that some retailers, aware of the consumers' diffculties in adopting the new currency, used the changeover to increase profits by increasing prices. We also propose an explanation of why this effect was smaller in more concentrated retail markets.euro, currency changeover, imperfect information, search costs, price setting.
