A Consistent Bootstrap Test for Conditional Density Functions with Time-Dependent Data Staff Working Paper 2001-21 Fuchun Li, Greg Tkacz This paper describes a new test for evaluating conditional density functions that remains valid when the data are time-dependent and that is therefore applicable to forecasting problems. We show that the test statistic is asymptotically distributed standard normal under the null hypothesis, and diverges to infinity when the null hypothesis is false.

Evaluating Factor Models: An Application to Forecasting Inflation in Canada Staff Working Paper 2001-18 Marc-André Gosselin, Greg Tkacz This paper evaluates the forecasting performance of factor models for Canadian inflation. This type of model was introduced and examined by Stock and Watson (1999a), who have shown that it is quite promising for forecasting U.S. inflation.

Affine Term-Structure Models: Theory and Implementation Staff Working Paper 2001-15 David Bolder Affine models describe the stylized time-series properties of the term structure of interest rates in a reasonable manner, they generalize relatively easily to higher dimensions, and a vast academic literature exists relating to their implementation. This combination of characteristics makes the affine class a natural introductory point for modelling interest rate dynamics.

Evaluating Linear and Non-Linear Time-Varying Forecast-Combination Methods Staff Working Paper 2001-12 Fuchun Li, Greg Tkacz This paper evaluates linear and non-linear forecast-combination methods. Among the non-linear methods, we propose a nonparametric kernel-regression weighting approach that allows maximum flexibility of the weighting parameters.

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.
