Confidence Regions for Calibrated Parameters in Computable General Equilibrium Models
(Université de Montréal. Département de sciences économiques., 1998)
We consider the problem of accessing the uncertainty of calibrated parameters in computable general equilibrium (CGE) models through the construction of confidence sets (or intervals) for these parameters. We study two ...
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 ...
Simulation-Based Finite-and Large-sample Inference Methods in Multivariate Regressions and Seemingly Unrelated Regressions
(Université de Montréal. Département de sciences économiques., 1998)
In the context of multivariate regression (MLR) and seemingly unrelated regressions (SURE) models, it is well known that commonly employed asymptotic test criteria are seriously biased towards overrejection. in this paper, ...
Simulation-Based Finite-Sample Normality Tests in Linear Regressions
(Université de Montréal. Département de sciences économiques., 1998)
In the literature on tests of normality, much concern has been expressed over the problems associated with residual-based procedures. Indeed, the specialized tables of critical points which are needed to perform the tests ...
Statistical Inference for Computable General Equilibrium Models with Application to a Model of the Moroccan Economy
(Université de Montréal. Département de sciences économiques., 1997)
We study the problem of measuring the uncertainty of CGE (or RBC)-type model simulations associated with parameter uncertainty. We describe two approaches for building confidence sets on model endogenous variables. The ...
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. ...
Finite-Sample Simulation-Based Inference in VAR Models with Applications to Order Selection and Causality Testing
(Université de Montréal. Département de sciences économiques., 2005)
Statistical tests in vector autoregressive (VAR) models are typically based on large-sample approximations, involving the use of asymptotic distributions or bootstrap techniques. After documenting that such methods can be ...
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 ...
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 ...
Causalités à court et à long terme dans les modèles VAR et ARIMA multivariés
(Université de Montréal. Département de sciences économiques., 1993)
La causalité au sens de Granger est habituellement définie par la prévisibilité d'un vecteur de variables par un autre une période à l'avance. Récemment, Lutkepohl (1990) a proposé de définir la non-causalité entre deux ...
