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...

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...

This paper generalizes the Bollerslev and Zhang (2003) approach for the estimation of loadings of asset pricing models using "realized" measures and co-measures of risk. We propose here to extend this approach by including higher-moments in asset pricing models. Estimations are conducted using...

This paper presents the recent developments of macro-econometric modelling and discusses their advantages and limits. We first present the Sims critique and the Lucas critique. These two critiques have opened two new ways of macro-modelling. On the one hand, the Structural VAR approach allows to...

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...

This study is devoted to the analysis of the main effects, on the Belgian economy, of various forms of tax shifting aimed at increasing taxes on energy and decreasing other taxes(mainly taxes on labour). Results show that, if the increase in energy taxes is combined with a reduction of taxes on...

This paper presents an analysis of the relationship between innovation, productivity and exports regarding the SMEs. The main research aim of this study consists in analyzing the hypothesis of firms’ conscious self-selection in the export markets. To measure innovation, we consider the...

Dans cet article, nous proposons des tests sur la forme de la distribution des erreurs dans un modèle de régression linéaire multivarié (RLM). Les tests que nous développons sont fonction des résidus obtenus par moindres carrés multivariés, lesquels sont standardisés de façon à ce que...

In this paper, we propose several finite-sample specification tests for multivariate linear regressions (MLR) with applications to asset pricing models. We focus on departures from the assumption of i.i.d. errors assumption, at univariate and multivariate levels, with Gaussian and non-Gaussian...
