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...

(VF)Cet article propose d'étudier la stabilité des performances de certains fonds de retraite anglais. Nos résultats montrent que les fonds investis en actions sont caractérisés par une réversion de leurs performances alors que les fonds obligataires connaissent une certaine pérennité...

The objective of this paper is to present the transformations of corporate governance in Asia\r\nsince the crisis of 1997. The analysis deals with 14 Asian countries during the period of 1997-\r\n2006. The important changes include the development of stocks markets, the new role of\r\nbanks and...

High-speed market connections and information processing improve the ability to seize trading opportunities, raising gains from trade. They also enable fast traders to process information before slow traders, generating adverse selection, and thus negative externalities. When investing in...

French Abstract: Les phénomènes financiers sont de plus en plus complexes. Les comportements des agents semblent s'écarter du paradigme naguère dominant de rationalité. Les crises économiques et la poussée régulatrice sont révélatrices des fissures dans l'édifice néoclassique....
