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...

The objective of this article is to analyze the impact of capital structure on profitability. This impact can be explained by three essential theories: signaling theory, tax theory and the agency costs theory. From a sample of 9136 firms distributed on seven sectors taken over the period...

This article aims to analyze the effect of debt on the profitability. This impact can be explained by three essential theories: signaling theory, the agency costs theory and tax theory. The sample consists of a panel of 1,078 French firms, unlisted, anonymous type and Limited Liability Company;...

This article aims to expand existing empirical knowledge on the impact of debt level on profitability of companies. We analyze a sample of 568 unlisted French companies (Agro-food sector) spanning over a period of 1999 to 2006. We show, by using the generalized method of moments (GMM), that debt...

The objective of this article is to analyze the impact of capital structure on profitability. This impact can be explained by three essential theories: signaling theory, tax theory and the agency costs theory. A sample of 1846 French industrial firms are taken over the period 1999-2006, as a...

L’objectif de cet article est d’analyser l’impact de la structure du capital sur la profitabilité. Nous montrons, à partir d’un échantillon de 1846 entreprises industrielles françaises prises sur la période 1999-2006, à l’aide d’une étude sur panel dynamique en utilisant la...

L’objectif de cet article est d’analyser l’impact de la structure du capital sur la profitabilité. Cet impact peut être expliqué par trois théories essentielles: la théorie du signal, l’influence de la fiscalité et la théorie de l’agence. Nous montrons, à partir d’un...
