This paper illustrates the usefulness of resampling based methods in the context of multiple (simultaneous) tests, with emphasis on econometric applications. Economic theory often suggests joint (or simultaneous) hypotheses on econometric models; consequently, the problem of evaluating joint...

A wide range of tests for heteroskedasticity have been proposed in the econometric and statistics literatures. Although a few exact homoskedasticity tests are available, the commonly employed procedures are quite generally based on asymptotic approximations which may not provide good size...

This paper studies the role of fluctuations in the aggregate price-earning ratio at different time-scales, for predicting stock returns and exploring the channels through which returns are forecasted. Using U.S. quartely data, we find that cycles in the price-earning ratio are strong and better...

French Abstract: Cet article vise à présenter et mettre en perspective les approches structurelles et non structurelles en économétrie de l'évaluation des politiques publiques. Si ces approches sont souvent opposées car correspondant à des démarches scientifiques différentes, elles se...

In this paper, we propose a simple econometric framework to disentangle the respective roles of monetary policy inertia and persistent shocks in interest rate rules. The procedure exploits the cross-equation restrictions provided by a DSGE model which is confronted to a monetary SVAR. We show...

Le modèle OPTIM permet de prévoir, chaque mois, les taux de croissance du PIB de la France et de ses principales composantes, pour le trimestre en cours et le trimestre suivant. Ce modèle mobilise un large éventail de données macro-économiques mensuelles et de données d’enquête,...

This paper shows that a multiple regression with two highly correlated explanatory variables, both of them with a near zero correlation with the dependent variable may correspond to a spurious regression or to a homeostatic model, with estimates highly sensible to outliers. The regression method...

Selon la maquette d’inflation pour la zone euro développée à la Banque de France, la reprise de l’inflation sous-jacente en 2007 est la conséquence de tensions cycliques et de la vive progression passée des prix d’importations.

Estimating mixture models still raises numerous questions, both theoretical and empirical. However, this class of model appears quite powerful for a parcimonious modelization of ill-behaved distribution, as it is the case with loans rate vis-à-vis the private sector collected by the Banque de...

Cet article expose la problématique de la volatilité des prix des matières premières, montre quels sont les moyens pour s’en protéger et explique comment les employer. Les instruments de couverture sont présentés en première section, en distinguant le type de besoin auquel ils...
