• Asymptotic Approximations in the Near-Integrated Model with a Non-Zero Initial Condition 

    Perron, Pierre; VODOUNOU, Cosme (Université de Montréal. Département de sciences économiques., 1998)
    This paper considers various asymptotic approximations in the near-integrated firstorder autoregressive model with a non-zero initial condition. We first extend the work of Knight and Satchell (1993), who considered the random walk case with a zero ...
  • An Autoregressive Spectral Density Estimator at Frequency Zero for Nonstationarity Tests 

    Perron, Pierre; Ng, Serena (Université de Montréal. Département de sciences économiques., 1996)
    Many unit root and cointegration tests require an estimate of the spectral density function at frequency zero at some process. Kernel estimators based on weighted sums of autocovariances constructed using estimated residuals from an AR(1) regression ...
  • Confidence Regions for Calibrated Parameters in Computable General Equilibrium Models 

    Abdelkader, Touhami; Dufour, Jean Marie (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 different setups under which this ...
  • Économétrie, théorie des tests et philosophie des sciences 

    Dufour, Jean Marie (Université de Montréal. Département de sciences économiques., 2000)
    Dans ce texte, nous revoyons certains développements récents de l’économétrie qui peuvent être intéressants pour des chercheurs dans des domaines autres que l’économie et nous soulignons l’éclairage particulier que l’économétrie peut jeter sur certains ...
  • Inflation dynamics and the New Keynesian Phillips Curve: an identification robust econometric analysis 

    Dufour, Jean Marie; Khalaf, Lynda; Kichian, Maral (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 ...
  • Methods to Estimate Dynamic Stochastic General Equilibrium Models 

    Ruge-Murcia, Francisco (Université de Montréal. Département de sciences économiques., 2003)
    This paper employs the one-sector Real Business Cycle model as a testing ground for four different procedures to estimate Dynamic Stochastic General Equilibrium (DSGE) models. The procedures are: 1 ) Maximum Likelihood, with and without measurement ...
  • Quadratic M-Estimators for ARCH-Type Processes 

    Meddahi, Nour; Renault, Éric (Université de Montréal. Département de sciences économiques., 1998)
    This paper addresses the issue of estimating semiparametric time series models specified by their conditional mean and conditional variance. We stress the importance of using joint restrictions on the mean and variance. This leads us to take into account ...
  • Sampling Interval and estimated Betas : Implications for the Presence of Transitory Components in Stock Prices 

    Perron, Pierre; VODOUNOU, Cosme (Université de Montréal. Département de sciences économiques., 1998)
    We provide a theoretical framework to explain the empirical finding that the estimated betas are sensitive to the sampling interval even when using continuously compounded returns. We suppose that stock prices have both permanent and transitory components. ...
  • The Seemingly Unrelated Dynamic Cointegration Regression Model and Testing for Purching Power Parity 

    MOON, Hyungsik Roger; Perron, Benoit (Université de Montréal. Département de sciences économiques., 2000)
    This paper studies seemingly unrelated linear models with integrated regressors and stationary errors. By adding leads and lags of the first differences of the regressors and estimating this augmented dynamic regression model by feasible generalized ...
  • Simulation-Based Finite-Sample Tests for Heteroskedasticity and ARCH Effects 

    Dufour, Jean Marie; Khalaf, Lynda; Bernard, Jean-Thomas; GENEST, Ian (Université de Montréal. Département de sciences économiques., 2001)
    A wide range of tests for heteroskedasticity have been proposed in the econometric and statistics literature. Although a few exact homoskedasticity tests are available, the commonly employed procedures are quite generally based on asymptotic approximations ...
  • Time Reversibility of Stationary Regular Finite State Markov Chains 

    McCausland, William J. (Université de Montréal. Département de sciences économiques., 2004)
    We propose an alternate parameterization of stationary regular finite-state Markov chains, and a decomposition of the parameter into time reversible and time irreversible parts. We demonstrate some useful properties of the decomposition, and propose ...
