- Abstract
- This paper – which takes into consideration overall experience with the Harmonised Index of Consumer Prices (HICP) as well as the improvements made to this measure of inflation since 2003 – finds that the HICP continues to fulfil the prerequisites for the index underlying the ECB’s definition of price stability. Nonetheless, there is scope for enhancing the HICP, especially by including owner-occupied housing (OOH) using the net acquisitions approach. Filling this long-standing gap is of utmost importance to increase the coverage and cross-country comparability of the HICP. In addition to integrating OOH into the HICP, further improvements would be welcome in harmonisation, especially regarding the treatment of product replacement and quality adjustment. Such measures may also help reduce the measurement bias that still exists in the HICP. Overall, a knowledge gap concerning the exact size of the measurement bias of the HICP remains, which calls for further research. More generally, the paper also finds that auxiliary inflation measures can play an important role in the ECB’s economic and monetary analyses. This applies not only to analytical series including OOH, but also to measures of underlying inflation or a cost of living index.

- Abstract
- The distributive trades sector, which is primarily accounted for by wholesale and retail trade, is not only economically important in its own right, but also relevant to monetary policy. Ultimately, it is retailers who set the actual prices of most consumer goods. They are the main interface between producers of consumer goods and consumers, with around half of private consumption accounted for by retail trade. The

- Abstract
- This paper assesses the degree of downward wage rigidity in Luxembourg using an administrative monthly data set on individual wages covering the entire economy over the period from January 2001 to January 2007. After limiting for measurement error, which would otherwise bias downwards the estimates of wage rigidity, we conclude that nearly all workers in Luxembourg are potentially subject to downward real wage rigidity. Our results are robust to different procedures to adjust for measurement error and methods for estimation of downward wage rigidity. We report relatively small differences in the frequency of nominal wage cuts across occupational groups and sectors. In addition, the observed rigidity does not seem to be driven predominantly by the absence of negative shocks. We show that the real wage rigidity is related to the automatic wage indexation, while additional factors might be necessary to explain the high degree of downward wage rigidity.

- Abstract
- This paper assesses the degree of wage flexibility in Luxembourg using an administrative data set on individual base wages covering the entire economy over the period 2001-2006 with monthly frequency. We find that the wage flexibility at the discretion of the firm is rather low once we limit measurement error and remove wage changes due to institutional factors (indexation, changes in statutory minimum wage, age and marital status). The so adjusted frequency of wage change lies between 5% and 7%. On average, wages change less often than consumer prices. Less than one percent of (nominal) wages are cut both from month to month and from year to year. Due to automatic wage indexation, wages appear to be subject to substantial downward real wage rigidity. Finally, wage changes tend to be highly synchronised as they are concentrated around the events of wage indexation and the month of January.

- Abstract
- This paper studies the behaviour of Internet prices. It compares price rigidities on the Internet and in traditional brick-and-mortar stores and provides a cross-country perspective. The data set covers a broad range of items typically sold over the Internet. It includes more than 5 million daily price quotes downloaded from price comparison web sites in France, Germany, Italy, the UK and the US. The following results emerge from our analysis. First, and contrary to the recent findings for common CPI data, Internet prices in the EU countries do not change less often than online prices in the US. Second, prices on the Internet are not necessarily more flexible than prices in traditional brick-and-mortar stores. Third, there is substantial heterogeneity in the frequency of price change across shop types and product categories. Fourth, the average price change on the Internet is relatively large, but smaller than the respective values reported for CPI data. Finally, panel logit estimates suggest that the likelihood of observing a price change is a function of both state- and time-dependent factors.

- Abstract
- This paper analyses the pricing behaviour of Luxembourg firms based on survey evidence. Luxembourg firms typically have low market share, many competitors and longstanding customer relationships. Price discrimination is frequently applied. A majority of firms use price review rules that include elements of state dependency. The median firm reviews and changes prices twice a year. The results suggest an almost equal share of firms applying forwardlooking, backward-looking and rules of thumb behaviour. The adjustment speed is faster when cost goes up and demand goes down than in the opposite cases. The most relevant theories explaining price rigidity are implicit contracts, cost-based pricing and explicit contracts. Increases in labour and other costs are the most important factors leading to price increases; for price reductions it is price reductions by competitors followed by declining labour costs.

- Abstract
- This paper presents original evidence on price setting in the euro area at the individual level. We use micro data on consumer (CPI) and producer (PPI) prices, as well as survey information. Our main findings are: (i) prices in the euro area are sticky and more so than in the US; (ii) there is evidence of heterogeneity and of asymmetries in price setting behaviour; (iii) downward price rigidity is only slightly more marked than upward price rigidity and (iv) implicit or explicit contracts and coordination failure theories are important, whereas menu or information costs are judged much less relevant by firms.

- Abstract
- This paper uses micro-level price data and analyses the behaviour of consumer prices in Luxembourg. We find that the median duration of consumer prices is roughly 8 months. The median durations of energy and unprocessed food are about 1.5 and 5 months, while prices of services typically change fewer than once a year. For some product types, such as non-energy industrial goods and processed food, a relatively large share of the observed price changes is reverted afterwards. With the exception of services, individual prices do not show signs of downward rigidity. On average, price decreases are as large as price increases. Price changes are determined both by state- and time-dependent factors. Accumulated price and wage inflation, wage adjustment due to indexation, the cash changeover and a larger number of competitors increase the probability of a price change, while pricing at attractive pricing points and price regulation have the opposite effect.

- 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
- This paper analyses the degree of price rigidity and of inflation persistence across different product categories with particular focus on regulated prices and services for the individual EU15 countries, as well as for the EU15 and the euro area aggregates. We show that services and HICP sub-indices considered being subject to price regulation exhibit larger degrees of nominal price rigidities, with less frequent but larger price index changes as well as stronger asymmetries between price index increases and decreases. With regard to what extent services and regulated prices contribute to the degree of overall inflation persistence, we find that, for most of the EU15 countries as well as for the EU15 and the euro area aggregates, excluding services from the full HICP results in a reduction in the measured degree of inflation persistence; for regulated indices such an effect is also discernible, albeit to a lesser extent.

- Abstract
- This paper analyses the degree of inflation persistence in the EU15, the euro area and each of its member states using disaggregate price indices from the Harmonised Index of Consumer Prices. Our results reveal substantial heterogeneity across countries and indices. The overall results, based on both parametric and non-parametric persistence measures, suggest a very moderate degree of median and mean inflation persistence. For most price indices we are able to reject the unit root hypothesis, as well as the notion of disaggregate inflation exhibiting a high degree of persistence. Durable goods and services tend to be relatively less persistent than other indices. Aggregation effects, both across indices and countries, tend to be present. We find structural breaks both owing to the change in the monetary regime and to the modified treatment of sales in the official HICP series. The latter tends to reduce the measured degree of inflation persistence.

- Abstract
- This paper investigates the transmission of monetary policy using data from a panel of Luxembourg firms. The results indicate that the sales accelerator may be at work. A very robust result is the negative effect of the user cost of capital on firms' investment ratio. Changes in user costs are significantly affected by changes in the monetary policy indicator. In addition, firm specific balance sheet characteristics, such as the lagged cash stock to capital ratio influence the investment behaviour according to the broad credit channel theory. Using various sample splits, it is shown that young firms, in particular, are more sensitive to user cost changes, sales growth and the lagged cash to capital ratio.
