Abstract: | Abstract. This paper analyses the evolution of inflation and of consumers' inflation perceptions in the aftermath of the euro cash changeover. It finds that the cross‐country variation of food product inflation was dependent on the complexity of conversion rates, with statistically significant and economically sizeable effects especially for low‐priced items sold in midpriced stores. The paper also shows that cross‐country differences in the mismatch of perceived and actual inflation were linked to differences in the complexity of conversion rates. These results are in line with theories of finite information‐processing capacities on the side of consumers. |
