Estimating New Keynesian Phillips Curves Using Exact Methods
The authors use simple new finite-sample methods to test the empirical relevance of the New Keynesian Phillips curve (NKPC) equation. -
Structural Change and Forecasting Long-Run Energy Prices
The authors test the statistical significance of Pindyck's (1999) suggested class of econometric equations that model the behaviour of long-run real energy prices. -
Exact Tests of Equal Forecast Accuracy with an Application to the Term Structure of Interest Rates
The author proposes a class of exact tests of the null hypothesis of exchangeable forecast errors and, hence, of the hypothesis of no difference in the unconditional accuracy of two competing forecasts. -
The Canadian Phillips Curve and Regime Shifting
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
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
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. -
Evaluating the Quarterly Projection Model: A Preliminary Investigation
This paper summarizes the results of recent research evaluating the Bank of Canada's Quarterly Projection Model (QPM). -
Some Explorations, Using Canadian Data, of the S-Variable in Akerlof, Dickens, and Perry (1996)
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 One-Factor Models of Short-Term Interest Rates
There currently exists in the literature several continuous-time one-factor models for short-term interest rates. This paper considers a wide range of these models that are nested into one general model. These models are approximated using both a discrete-time model and a model that accounts for aggregation effects over time, and are estimated by both the […]
