Testing Mean-Variance Efficiency in CAPM with Possibly Non-Gaussian Errors : An Exact Simulation-Based Approach
(Université de Montréal. Département de sciences économiques., 2002)
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 ...
Finite-Sample Diagnostics for Multivariate Regressions with Applications to Linear Asset Pricing Models
(Université de Montréal. Département de sciences économiques., 2003)
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, ...
Identification, Weak Instruments and Statistical Inference in Econometrics
(Université de Montréal. Département de sciences économiques., 2003)
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 ...
Méthodes d’inférence exactes pour un modèle de régression avec erreurs AR(2) gaussiennes
(Université de Montréal. Département de sciences économiques., 2003)
Ce texte propose des méthodes d’inférence exactes (tests et régions de confiance) sur des modèles de régression linéaires avec erreurs autocorrélées suivant un processus autorégressif d’ordre deux [AR(2)], qui peut être ...
Projection-Based Statistical Inference in Linear Structural Models with Possibly Weak Instruments
(Université de Montréal. Département de sciences économiques., 2003)
It is well known that standard asymptotic theory is not valid or is extremely unreliable in models with identification problems or weak instruments [Dufour (1997, Econometrica), Staiger and Stock (1997, Econometrica), Wang ...
Exact Skewness-Kurtosis Tests for Multivariate Normality and Goodness-of-fit in Multivariate Regressions with Application to Asset Pricing Models
(Université de Montréal. Département de sciences économiques., 2003)
We study the problem of testing the error distribution in a multivariate linear regression (MLR) model. The tests are functions of appropriately standardized multivariate least squares residuals whose distribution is ...
Investment, Taxation and Econometric Policy Evaluation: Some Evidence on the Lucas Critique
(Université de Montréal. Département de sciences économiques., 1981)
Some Robust Exact Results on Sample Autocorrelations and Tests of Randomness
(Université de Montréal. Département de sciences économiques., 1984)
Ce Texte Presente Plusieurs Resultats Exacts Sur les Seconds Moments des Autocorrelations Echantillonnales, Pour des Series Gaussiennes Ou Non-Gaussiennes. Nous Donnons D'abord des Formules Generales Pour la Moyenne, la ...
