- Abstract
- An aggregation exercise is proposed that aims at investigating whether the fast average adjustment of the disaggregate inflation series of the euro area CPI translates into the slow adjustment of euro area aggregate inflation. We first estimate a dynamic factor model for 404 inflation sub-indices of the euro area CPI. This allows to decompose the dynamics of inflation sub-indices in two parts: one due to a common "macroeconomic" shock and one due to sector specific "idiosyncratic" shocks. Although "idiosyncratic" shocks dominate the variance of sectoral prices, one common factor, which accounts for 30 per cent of the overall variance of the 404 disaggregate inflation series, is the main driver of aggregate dynamics. In addition, the heterogeneous propagation of this common shock across sectoral inflation rates, and in particular its slow propagation to inflation rates of services, generates the persistence of aggregate inflation. We conclude that the aggregation process explains a fair amount of aggregate inflation persistence.

- Abstract
- This paper provides a summary of current knowledge on inflation persistence and price stickiness in the euro area, based on research findings that have been produced in the context of the Inflation Persistence Network. The main findings are: i) Under the current monetary policy regime, the estimated degree of inflation persistence in the euro area is moderate; ii) Retail prices in the euro area are more sticky than in the US; iii) There is significant sectoral heterogeneity in the degree of price stickiness; iv) Price decreases are not uncommon. The paper also investigates some of the policy implications of these findings.

- Abstract
- Do asset prices affect real activity? This question has taken on a new importance in recent years, as asset values first surged at the end of 1990s and, thereafter, dramatically retreated. This report reviews the available theoretical and empirical evidence regarding asset price and wealth effects in Europe and some other major economies. The main focus of this report is on consumption effects via the wealth channel, reflecting the bulk of literature on the effects of asset prices. However, asset price effects on investment via the Tobin
