We discuss statistical inference problems associated with identification and testability in econometrics, and we emphasize the common nature of the two issues. After reviewing the relevant statistical notions, we consider in turn inference in nonparametric models and recent developments on...

In this paper, we characterize the asymmetries of the smile through multiple leverage effects in a stochastic dynamic asset pricing framework. The dependence between price movements and future volatility is introduced through a set of latent state variables. These latent variables can capture...

Latent variable models in finance originate both from asset pricing theory and time series analysis. These two strands of literature appeal to two different concepts of latent structures, which are both useful to reduce the dimension of a statistical model specified for a multivariate time...

En zone euro, les rigidités salariales nominales et la vitesse de la politique désinflationniste apparaissent comme des facteurs déterminants du « ratio de sacrifice ». En France, les changements de salaires sont assez fréquents mais largement prédéterminés, ce qui crée de la rigidité...

Several legal missions from the Federal Planning Bureau require the construction of long-term macroeconomic scenarios for the Belgian economy. In order to increase the consistency of these scenarios and to build them within a rigorous theoretical framework, it appeared important to develop a new...

The concepts of potential growth and output gap are important tools to evaluate the state of the business cycle and to assess the supply-side capacity of an economy. They have also become an essential ingredient of the European fiscal surveillance process. However, the global economy is facing...

This paper presents the main improvements carried out to the macroeconometric model MZE since its creation in 2003. We have back-calculated the series over the period 1980-1995, in order to make the model more stable. To our knowledge, this paper is the first application of Kllians (1998) method...

L'objet de ce papier est l'étude des déterminants de l'offre de riz des ménages agricoles malgaches à partir des enquêtes des Observatoires Ruraux de 1996. Plusieurs démarches sont envisagées. Tout d'abord, l'étude des déterminants du rendement du riz au niveau des parcelles permet de...
