Cet article propose un réexamen de la spécification de la fonction de demande de monnaie de la zone euro. En effet, les spécifications traditionnelles conduisent à des résultats parfois peu satisfaisants : instabilité des coefficient de court et long termes ; écarts relativement...

In recent years, the dynamics of M3 in the euro area have been driven by two factors: a strong preference for liquidity, observed between 2001 and 2003, followed by a normalisation, at a relatively moderate pace, of portfolio behaviour; as regards the counterparts, changes in M3 and net external...

L'objectif est de spécifier la nature des comportements saisonniers de la demande de séjours touristiques en Tunisie en utilisant les outils récents d'analyse des séries temporelles mensuelles. Les séries disponibles (dépenses touristiques, prix, revenus, nombre de nuitées, capacités...

In a Constant Proportion Portfolio Insurance (CPPI) framework, a constant risk exposure is defined by the multiple of the strategy. This article proposes an alternative conditional multiple estimation model, which is based on an autoregressive quantile regression dynamic approach. We estimate...

We consider the problem of testing whether the observations X1, · · ·, Xn of a time series are independent with unspecified (possibly nonidentical) distributions symmetric about a common known median. Various bounds on the distributions of serial correlation coefficients are proposed:...

In this paper, we develop finite-sample inference procedures for stationary and nonstationary autoregressive (AR) models. The method is based on special properties of Markov processes and a split-sample technique. The results on Markovian processes (intercalary independence and truncation) only...

L’ISMA est un des principaux outils de diagnostic conjoncturel de la Banque de France. Publié chaque mois, il estime la croissance du PIB français pour le prochain trimestre, en se basant sur les données d’enquêtes de la Banque de France.

In this paper, we estimate and analyse a set of equations of French inflation for forecasting purpose at the horizon of three months, six months and one year. A different equation is associated to each horizon. This approach has the advantage of modeling directly the variable of interest at the...

This paper first presents a time-series analysis of factors influencing aggregate health care expenditure in some OECD countries. We focus on supply-side factors (especially the diffusion of medical technologies) and first estimate a single model on six countries. The results suggest that...
