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...

In this paper, we use identification-robust methods to assess the empirical adequacy of a New Keynesian Phillips Curve (NKPC) equation. We focus on the Gali and Gertler's (1999) specification, on both U.S. and Canadian data. Two variants of the model are studied: one based on a...

This paper proposes a new nonparametric test for conditional independence, which is based on the comparison of Bernstein copula densities using the Hellinger distance. The test is easy to implement because it does not involve a weighting function in the test statistic, and it can be applied in...

With the case study of the city of Marseille over the period 1997-2000, this article attempts to analyze the motivation of the city for issuing guaranteed municipal bond and to identify the determining factors of the risk premium. The case study shows the existence of the juridical risk that...

The present study proposes to examine the link between the organisational policies of the investment management companies and the performance of the managed funds. This study is based on about fifteen exploratory talks organized with persons in charge of investment management companies, and on...

Dans un contexte de crise, il est facile de perdre ses repères, et les comportements irrationnels actuels, la panique généralisée des investisseurs le démontrent. Alors que de nombreuses cessations de paiement des ménages américains étaient constatées depuis plusieurs mois, de nombreux...
