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...

This aim of this study is to estimate the price of coffee and cocoa using a methodology based on Hodrick-Prescott filter, Kalman filter and a Markov Switching Model which, unlike linear models, allows the parameters to vary depending on the economic situation, the transitions between regimes are...

The purpose of this paper is to study the model belongs to the family of structural equation models with data varying both across individuals (sectors) and in time. A complete theoretical analysis is developed in this work for the case of a dynamic recursive structure. Maximum likelihood...

Résumé: Cet article analyse le comportement cyclique des flux de trésorerie et notamment ses propriétés statistiques à travers une classe de modèles ARMA avec erreur GARCH, notée ARIMA-GARCH ; cette classe inclut une tendance stochastique, la dépendance à court terme ainsi que le terme...

We propose methods for testing hypothesis of non-causality at various horizons, as defined in Dufour and Renault (1998, Econometrica). We study in detail the case of VAR models and we propose linear methods based on running vector autoregressions at different horizons. While the hypotheses...

Le crédit interentreprises est un des canaux de transmission du risque de défaillance des entreprises. Les impayés sur effets de commerce révèlent les interdépendances entre secteurs et leur potentiel de contagion, dès lors que les montants en jeu sont importants.

This paper proposes an indirect inference (Gourieroux, Monfort and Renault, 1993; Smith, 1993) estimation method for a large class of dynamic equilibrium models. Our approach is based on the observation that the econometric structure of these systems naturally generates auxiliary equilibria that can...

Since July 2003, the Banque de France has been using seasonally adjusted (SA) data for the monthly reporting of national monetary developments, with renewed statistical tools. Before the start of the single currency in 1999, the Banque de France already calculated seasonally adjusted data, using...

The analysis of seasonality in economics and the development of new seasonal adjustment procedures have been following new directions in the last twenty years. We study this question through the work performed at the Banque de France (Monetary Statistic and Studies Directorate) to compile new...

This paper deals with statistics�and econometrics�properties of fractionally integra- ted GARCH (FIGARCH). We compare these characteristics with those of traditional models. We insist on the GARCH exponential/IGARCH in�nite decrease of volatility impact. Then, we apply it on three Tunisian...
