  • Asymptotic Distribution of a Simple Linear Estimator for VARMA Models in Echelon Form 

    Dufour, Jean Marie; TAREK, Jouini (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 ...
  • Distribution-Free Bounds for Serial Correlation Coefficients in Heteroskedastic Symmetric Time Series 

    Dufour, Jean Marie; Farhat, Abdeljelil; HALLIN, Marc (Université de Montréal. Département de sciences économiques., 2005)
    We consider the problem of testing whether the observations X1, ..., Xn of a time series are independent with unspecified (possibly nonidentical) distributions symmetric about a common known median. Various bounds on the distributions of serial correlation ...
  • Finite-Sample Simulation-Based Inference in VAR Models with Applications to Order Selection and Causality Testing 

    Dufour, Jean Marie; Jouini, Tarek (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 very misleading even with ...
  • 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 ...
  • Organizational Design of R&D Activities 

    Ambec, Stefan; Poitevin, Michel (Université de Montréal. Département de sciences économiques., 2001)
    This paper addresses the question of whether R&D should be carried out by an independent research unit or be produced in-house by the firm marketing the innovation. We define two organizational structures. In an integrated structure, the firm that ...
  • 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 ...
  • A Semi-Parametric Factor Model for Interest Rates 

    Ghysels, Eric; Ng, Serena (Université de Montréal. Département de sciences économiques., 1996)
    Understanding the dynamics of interest rates and the term structure has important implications for issues as diverse as real economic activity, monetary policy, pricing of interest rate derivative securities and public debt financing. Our paper follows ...
