Development of Finns' price knowledge after the changeover to the euro

This longitudinal study examines the 2002 changeover to the euro in Finland in order to find out how long it takes consumers to learn grocery prices in the new currency. We are especially interested in the influence of age on the process. We used price estimate data and market price data, with six data-collection points over 5 years, the first one just before the changeover and the last one 5 years after it. As expected, consumer price knowledge was clearly weaker immediately after the changeover than during the era of national currency. However, it has not improved significantly in 5 years. The probable reasons for the decreased price knowledge are the diminution of nominal values brought by the changeover (1 euro equals approximately 6 Finnish marks) and general indifference to prices, especially low ones, brought by the increasing standard of living.
