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...

In this paper we propose exact likelihood-based mean-variance efficiency tests of the market portfolio in the context of Capital Asset Pricing Model (CAPM), allowing for a wide class of error distributions which include normality as a special case. These tests are developed in the framework of...

In this paper, we propose exact inference procedures for asset pricing models that can be formulated in the framework of a multivariate linear regression (CAPM), allowing for stable error distributions. The normality assumption on the distribution of stock returns is usually rejected in...

This paper determines which gravity models are the best adapted to the study of the trade evolution of several economic areas and the behaviors heterogeneity of the countries that belong to these areas (fixed effect model; random effect model). Applied to the countries of UE15, NAFTA, MERCOSUR,...

This paper determines which are, among different type of gravity model, those best adapted to the study of the evolution of trade of several economic areas and of the heterogeneity of the behaviors of the countries constitutive of these zones (fixed effect model; random effect model; model with...

This article analysis diversity of growth path for the UE-27 countries, the other Eastern European countries which developed a partnership with UE like Ukraine or Russia, and for the Mediterranean countries (Morocco, Algeria, Tunisia, Turkey) which signed the 1995 Barcelona agreements. The first...
