Asymptotic Distribution of a Simple Linear Estimator for VARMA Models in Echelon Form
(Université de Montréal. Département de sciences économiques., 2005)In this paper, we study the asymptotic distribution of a simple two-stage (Hannan-Rissanen-type) linear estimator for stationary invertible vector autoregressive moving average (VARMA) models in the echelon form representation. General conditions for ... -
Exact Multivariate Tests of Asset Pricing Models with Stable Asymmetric Distributions
(Université de Montréal. Département de sciences économiques., 2005)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 ... -
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 invariant to the unknown cross-equation ... -
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, at univariate and multivariate ... -
Finite-sample inference methods for simultaneous equations and models with unobserved and generated regressors
(Université de Montréal. Département de sciences économiques., 1998)We propose finite sample tests and confidence sets for models with unobserved and generated regressors as well as various models estimated by instrumental variables methods. The validity of the procedures is unaffected by the presence of identification ... -
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 in turn inference in nonparametric ... -
Inflation dynamics and the New Keynesian Phillips Curve: an identification robust econometric analysis
(Université de Montréal. Département de sciences économiques., 2005)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 ... -
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. ...
