Inflation differentials in the euro area : size, causes, economic policy implications and relative position of Belgium
Both the size and the persistence of inflation differentials in the euro area have been the subject of a large number of studies in recent years. These studies have tried to determine the causes of these differentials as well as their implications not only for the implementation of the common monetary policy but also in terms of the macroeconomic policies needed at the country level. Indeed, since the start of Stage Three of the EMU, countries can no longer correct country-specific imbalances or idiosyncratic shocks through changing their national monetary policy stance. As a consequence, it may be deemed fit, in some cases, to take appropriate policy measures aimed at reducing inflation differentials. The article tackles the case of Belgium, in which country the inflation differentials vis-Ć -vis the euro area appear to be relatively small and do not seem to show any persistence or any systematic upward or downward bias. However, empirical studies based on the āBalassa-Samuelsonā theory have concluded that Belgium should be prone to a relatively high inflation rate. This theory holds that, on restrictive assumptions, a real appreciation (or positive inflation differential) is generated in countries showing the most rapid growth of the productivity differential between the traded and non-traded goods sectors. The article goes into those rather surprising results. The authors observed a pronounced increase of relative productivity in Belgium and a strong positive correlation between relative productivity and relative prices, measured by the value added deflator, which proves to be consistent with the theory and the results of previous studies. These studies have typically assumed that the tradable sector showed purchasing power parity. In that case, the pronounced increase in relative prices has strong implications for the real exchange rate (or inflation differentials). However, the authors found empirical evidence against this hypothesis in the Belgian case. Indeed, the real exchange rate in the tradable sector depreciated strongly in the seventies and the early eighties. This depreciation in the tradable sector offset the impact of the positive relative price differential, causing the real exchange rate for the economy as a whole to be relatively stable. Belgium should therefore not be an economy prone to high inflation. As the HICP is the main indicator monitored by the European monetary authorities, it was important to examine whether such conclusions could also be drawn for the consumer price index. The authors found similar results, namely a stable real exchange rate for the Belgian economy as a whole during the period under review and, therefore, the absence of any structural reason for inflation to be systematically higher in Belgium. It may thus be concluded that significant and persistent inflation differentials between Belgium and the euro area or a systematic bias in any particular direction are unlikely and, therefore, that the European monetary policy is appropriate for the Belgian economy in the current environment.Real exchange rates, Inflation differentials, Balassa-Samuelson effect, European Monetary Union
Price-setting behaviour in Belgium : what can be learned from an ad hoc survey ?
The article reports the results of an ad hoc survey on price-setting behaviour conducted in February 2004 among 2,000 Belgian firms. The reported results clearly deviate from a situation of perfect competition and show that firms have some market power. Pricing-to-market is applied by a majority of industrial firms. Prices are rather sticky. The average duration between two consecutive price reviews is 10 months, whereas it amounts to 13 months between two consecutive price changes. This evidence is consistent with the fact that both the price-reviewing process and the act of changing a price entail specific costs. Most firms adopt time-dependent price-reviewing under normal circumstances. However, when specific events occur, the majority will adopt a state-dependent behaviour. Evidence is found in favour of both nominal (mainly implicit and explicit contracts) and real rigidities (including fl at marginal costs and counter-cyclical movements in desired mark-ups), in line with the recent macro-literature where the interplay between both types of rigidity is emphasised. The survey results point to a non-negligible degree of non-optimal price-setting, suggesting that informational frictions could also be a source of sluggishness in the inflation process.price-setting behaviour, price rigidity, real rigidity, survey, time-dependent pricing, pricing-to-market
Why are Prices Sticky? Evidence from Business Survey Data
This paper offers new insights on the price setting behaviour of German retail firms using a novel dataset that
consists of a large panel of monthly business surveys from 1991-2006. The firm-level data allows matching changes
in firms' prices to several other firm-characteristics. Moreover, information on price expectations allow analyzing
the determinants of price updating. Using univariate and bivariate ordered probit specifications, empirical menu
cost models are estimated relating the probability of price adjustment and price updating, respectively, to both
time- and state- dependent variables. First, results suggest an important role for state-dependence; changes in
the macroeconomic and institutional environment as well as firm-specific factors are significantly related to the
timing of price adjustment. These findings imply that price setting models should endogenize the timing of price
adjustment in order to generate realistic predictions concerning the transmission of monetary policy. Second, an
analysis of price expectations yields similar results providing evidence in favour of state-dependent sticky plan
models. Third, intermediate input cost changes are among the most important determinants of price adjustment
suggesting that pricing models should explicitly incorporate price setting at different production stages. However, the results show that adjustment to input cost changes takes time indicating "additional stickiness" at the last stage of processing
