• 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.

• 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.

• 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.
