Testing for a Structural Break in the Volatility of Real GDP Growth in Canada Staff Working Paper 2001-9 Alexandre Debs This study tests for a structural break in the volatility of real GDP growth in Canada following the methodology of McConnell and Quiros (1998). A break is found in the first quarter of 1991.

On the Nature and the Stability of the Canadian Phillips Curve Staff Working Paper 2001-4 Maral Kichian This paper empirically determines why, during the 1990s, inflation in Canada was consistently more stable than predicted by the fixed-coefficients Phillips curve. A time-varying-coefficient model, where all the parameters adjust simultaneously, shows that the behaviour of expectations was probably a major contributing factor.

Exact Non-Parametric Tests for a Random Walk with Unknown Drift under Conditional Heteroscedasticity Staff Working Paper 2001-2 Richard Luger This paper proposes a class of linear signed rank statistics to test for a random walk with unknown drift in the presence of arbitrary forms of conditional heteroscedasticity.

Fractional Cointegration and the Demand for M1 Staff Working Paper 2000-13 Greg Tkacz Using wavelets, the author estimates the fractional order of integration of a common long-run money-demand relationship whose parameters are obtained from a full-information maximum-likelihood procedure.

Testing the Pricing-to-Market Hypothesis: Case of the Transportation Equipment Industry Staff Working Paper 2000-8 Lynda Khalaf, Maral Kichian Pricing-to-market (PTM) theory suggests that monopolistic firms which export adjust their destination-specific markups in reaction to exchange rate shocks. These adjustments limit changes in the price of their exports.

Estimating the Fractional Order of Integration of Interest Rates Using a Wavelet OLS Estimator Staff Working Paper 2000-5 Greg Tkacz The debate on the order of integration of interest rates has long focused on the I(1) versus I(0) distinction. In this paper, we use instead the wavelet OLS estimator of Jensen (1999) to estimate the fractional integration parameters of several interest rates for the United States and Canada from 1948 to 1999.

GAUSS™ Programs for the Estimation of State-Space Models with ARCH Errors: A User's Guide Staff Working Paper 2000-2 Maral Kichian State-space models have long been popular in explaining the evolution of various economic variables. This is mainly because they generally have more economic content than do others in their class of parsimonious models (for example, VARs). Yet, in spite of their advantages, use of these models until recently was limited by the assumption that all […] Content Type(s): Staff research, Staff working papers Topic(s): Econometric and statistical methods JEL Code(s): C, C3, C32, C8, C82, C87, C89
Pricing Interest Rate Derivatives in a Non-Parametric Two-Factor Term-Structure Model Staff Working Paper 1999-19 John Knight, Fuchun Li, Mingwei Yuan Diffusion functions in term-structure models are measures of uncertainty about future price movements and are directly related to the risk associated with holding financial securities. Correct specification of diffusion functions is crucial in pricing options and other derivative securities. In contrast to the standard parametric two-factor models, we propose a non-parametric two-factor term-structure model that […] Content Type(s): Staff research, Staff working papers Topic(s): Econometric and statistical methods, Market structure and pricing JEL Code(s): C, C1, C14, C2, C22, G, G1, G13
Forecasting GDP Growth Using Artificial Neural Networks Staff Working Paper 1999-3 Greg Tkacz, Sarah Hu Financial and monetary variables have long been known to contain useful leading information regarding economic activity. In this paper, the authors wish to determine whether the forecasting performance of such variables can be improved using neural network models. The main findings are that, at the 1-quarter forecasting horizon, neural networks yield no significant forecast improvements.

A Discussion of the Reliability of Results Obtained with Long-Run Identifying Restrictions Staff Working Paper 1998-4 Pierre St-Amant, David Tessier In a recent article, Faust and Leeper (1997) discuss reasons why inference from structural VARs identified with long-run restrictions may not be reliable. In this paper, the authors argue that there are reasons to believe that Faust and Leeper's arguments are not devastating in practice. First, simulation exercises suggest that this approach does well when […] Content Type(s): Staff research, Staff working papers Topic(s): Econometric and statistical methods JEL Code(s): C, C3
