- Abstract
- We analyse the adjustment of retail and services prices in a period of low inflation, using a set of individual price data from the German Consumer Price Index that covers the years 1998 to 2003. We strong find evidence of time- and statedependent price adjustment. Most importantly, the differences in "unconditional" sectoral price flexibility are found to be linked to input price volatility.

- Abstract
- This paper documents patterns of price setting at the retail level in the euro area, summarized in six stylized facts. First, the average euro area monthly frequency of price adjustment is 15 p.c., compared to about 25 p.c. in the US. Second, the frequency of price changes is characterized by substantial cross product heterogeneity - prices of oil and unprocessed food products change very often, while price adjustments are less frequent for processed food, non energy industrial goods and services. Third, cross country heterogeneity exists but is less pronounced. Fourth, price decreases are not uncommon. Fifth, price increases and decreases are sizeable compared to aggregate and sectoral inflation rates. Sixth, price changes are not highly synchronized across retailers. Moreover, the frequency of price changes in the euro area is related to several factors, such as seasonality, outlet type, indirect taxation, pricing practices as well as aggregate or product specific inflation.

- Abstract
- In several studies, hedonic methods have been used successfully for the ex post assessment of the accuracy of inflation measurement. Most of those studies relate to high-tech products, with respect to which traditional methods of compiling price indices often fail. We apply hedonic methods to rental housing services, which display less quality progress. However, as German households devote about 10 % of their total expenditure to rented housing services, even a small bias in this field might induce a substantial distortion in overall inflation measurement. On the basis of data from the German Socio-Economic Panel, we perform a hedonic analysis of housing rents and compile different price indices. Overall, we conclude that there is some evidence of an understatement of rent inflation in the official rent index for West Germany at the beginning of the 1990s.
