C52 - Model Evaluation, Validation, and Selection

• The Canadian Phillips Curve and Regime Shifting

  Staff Working Paper 2003-32 Frédérick Demers

  Phillips curves are generally estimated under the assumption of linearity and parameter constancy. Linear models of inflation, however, have recently been criticized for their poor forecasting performance.

• A Stochastic Simulation Framework for the Government of Canada's Debt Strategy

  Staff Working Paper 2003-10 David Bolder

  Debt strategy is defined as the manner in which a government finances an excess of government expenditures over revenues and any maturing debt issued in previous periods. The author gives a thorough qualitative description of the complexities of debt strategy analysis and then demonstrates that it is, in fact, a problem in stochastic optimal control.

• Testing the Stability of the Canadian Phillips Curve Using Exact Methods

  Staff Working Paper 2003-7 Lynda Khalaf, Maral Kichian

  Postulating two different specifications for the Canadian Phillips curve (a purely backwardlooking model, and a partly backward-, partly forward-looking model), the authors test for structural breaks in the parameters of the equation. In each case, they account for the possibilities that: (i) breaks can be discrete, or continuous, and (ii) available data samples may be too small to justify using asymptotically valid structural-change tests.
