A Test of New Aggregate Damand Curvature Properties
(Université de Montréal. Département de sciences économiques., 1988)In This Paper We Present and Implement an Econometric Test of Both Negative Semi-Definiteness of the Matrix of Compensated Price Effects and of the Negative Quasi-Definiteness of the Matrix of Uncompensated Price Effects. This Test Allows Us to Evaluate ... -
Testing for a Unit Root in Panels with Dynamic Factors
(Université de Montréal. Département de sciences économiques., 2002)This paper studies testing for a unit root for large n and T panels in which the cross-sectional units are correlated. To model this cross-sectional correlation, we assume that the data is generated by an unknown number of unobservable common factors. ... -
Testing for Homogeneity in Demand Systems when the Regressors Are Non-Stationary

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 normality as a special case. ... -
Testing Normality : A GMM Approach
(Université de Montréal. Département de sciences économiques., 2002)In this paper, we consider testing marginal normal distributional assumptions. More precisely, we propose tests based on moment conditions implied by normality. These moment conditions are known as the Stein (1972) equations. They coincide with the ... -
Tests multiples simulés et tests de normalité basés sur plusieurs moments dans les modèles de régression
(Université de Montréal. Département de sciences économiques., 2005)Cet article illustre l’applicabilité des méthodes de rééchantillonnage dans le cadre des tests multiples (simultanés), pour divers problèmes économétriques. Les hypothèses simultanées sont une conséquence habituelle de la théorie économique, de sorte ... -
Tests of Conditional Asset Pricing Models in the Brazilian Stock Market
(Université de Montréal. Département de sciences économiques., 1997)In this paper, we test a version of the conditional CAPM with respect to a local market portfolio, proxied by the Brazilian stock index during the 1976-1992 period. We also test a conditional APT model by using the difference between the 30-day rate ... -

Tests of Joint Hypotheses for Time Series Regression with a Unit Root
(Université de Montréal. Département de sciences économiques., 1986)This Paper Studies Tests of Joint Hypotheses in Time Series Regression with a Unit Root in Which Weakly Dependent and Heterogeneously Distributed Innovations Are Allowed. We Consider Two Types of Regression: One with a Constant and Lagged Dependent ... -
A Theoretical Comparison Between Integrated and Realized Volatilies
(Université de Montréal. Département de sciences économiques., 2001)In this paper, we provide both qualitative and quantitative measures of the cost of measuring the integrated volatility by the realized volatility when the frequency of observation is fixed. We start by characterizing for a general diffusion the ... -
