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 those HICP...

This paper reports the results of a survey conducted by the Banque de France during winter 2003-2004 to investigate the price-setting behavior of French manufacturing companies. Prices are found to adjust infrequently; the median firm modifies its price only once a year. Price reviews are more...

In this paper, we seek to estimate the sacrifice ratio of the euro area using a small DSGE model where prices and wages are sticky. We estimate model's parameters so as to minimize the distance between VAR-based and model-based covariances of a set of variables. The estimated value of the...

This study investigates the pricing behaviour of firms in the euro area on the basis of surveys conducted by nine Eurosystem national central banks, covering more than 11,000 firms. The results, robust across countries, show that firms operate in monopolistically competitive markets, where...

La littérature sur l'instabilité macroéconomique couvre un champ extrêmement vaste qui se révèle par le spectre très large de mesures utilisées pour appréhender ce phénomène. Le choix de la mesure de l'instabilité macroéconomique apparait généralement peu discuté sous le...

We introduce a tractable class of non-affine price processes with multifrequency stochastic volatility and jumps. The specifi cations require few fixed parameters and deliver fast option pricing. One key ingredient is a tight link between jumps and volatility regimes, as asset pricing theory...

French abstract: Le présent papier formalise un nouveau modèle de dynamique du système des prix du marché action, capable de saisir un large spectre de phénomènes renseignés par la littérature académique financière. Le modèle s’attache particulièrement à rendre compte de trois...

Whereas the process of integration economic is accentuated in Europe, regional integration dynamics of space seems to be a crucial issue. Reflexions engaged, in particular through the SDEC, aim at promoting a voluntarist policy of polycentric adjustment of European space. Thus we are led to...

The Wishart Autoregressive (WAR) process is a multivariate process of stochastic positive definite matrices. The WAR is proposed in this paper as a dynamic model for stochastic volatility matrices. It yields simple nonlinear forecasts at any horizon and has factor representation, which separates...

Cet article compare la croissance potentielle d’un panel d’économies composé de la France, de la zone euro, des États-Unis et du Japon. Il met en évidence la situation favorable des États-Unis par rapport à l’Europe et au Japon.
