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.

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.

The Application of Artificial Neural Networks to Exchange Rate Forecasting: The Role of Market Microstructure Variables Staff Working Paper 2000-23 Nikola Gradojevic, Jing Yang Artificial neural networks (ANN) are employed for high-frequency Canada/U.S. dollar exchange rate forecasting. ANN outperform random walk and linear models in a number of recursive out-of- sample forecasts.

Steps in Applying Extreme Value Theory to Finance: A Review Staff Working Paper 2000-20 Younes Bensalah Extreme value theory (EVT) has been applied in fields such as hydrology and insurance. It is a tool used to consider probabilities associated with extreme and thus rare events. EVT is useful in modelling the impact of crashes or situations of extreme stress on investor portfolios.

Employment Effects Of Nominal-Wage Rigidity: An Examination Using Wage-Settlements Data Staff Working Paper 2000-14 Umar Faruqui The argument advocating a moderate level of inflation based on the downward nominal-wage rigidity (DNWR) hypothesis rests on three factors: its presence, extent, and negative impact in the labour market. This paper focuses on the employment effect of DNWR. Content Type(s): Staff research, Staff working papers Research Topic(s): Labour markets JEL Code(s): C, C2, C23, J, J2, J23, J3, J30
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.

Non-Parametric and Neural Network Models of Inflation Changes Staff Working Paper 2000-7 Greg Tkacz Previous studies have shown that interest rate yield spreads contain useful information about future changes in inflation. However, such studies have for the most part focused on linear models, ignoring potential non-linearities between interest rates and inflation.

Some Explorations, Using Canadian Data, of the S-Variable in Akerlof, Dickens, and Perry (1996) Staff Working Paper 2000-6 Seamus Hogan, Lise Pichette A number of authors have suggested that economies face a long-run inflation-unemployment trade-off due to downward nominal-wage rigidity. This theory has implications for the nature of the short-run Phillips curve when wage inflation is low.
