Real Time Detection of Structural Breaks in GARCH Models

Staff Working Paper 2009-31 Zhongfang He, John M. Maheu
A sequential Monte Carlo method for estimating GARCH models subject to an unknown number of structural breaks is proposed. Particle filtering techniques allow for fast and efficient updates of posterior quantities and forecasts in real time.

Simulations du ratio du service de la dette des consommateurs en utilisant des données micro

Staff Working Paper 2009-18 Ramdane Djoudad
The author constructs a formal analytic framework to simulate the impact of various economic shocks on the household debt-service ratio, using data from the Canadian Financial Monitor (CFM) survey.

Non-Linearities, Model Uncertainty, and Macro Stress Testing

Staff Working Paper 2008-30 Miroslav Misina, David Tessier
A distinguishing feature of macro stress testing exercises is the use of macroeconomic models in scenario design and implementation. It is widely agreed that scenarios should be based on "rare but plausible" events that have either resulted in vulnerabilities in the past or could do so in the future.

Optimization in a Simulation Setting: Use of Function Approximation in Debt Strategy Analysis

Staff Working Paper 2007-13 David Bolder, Tiago Rubin
The stochastic simulation model suggested by Bolder (2003) for the analysis of the federal government's debt-management strategy provides a wide variety of useful information. It does not, however, assist in determining an optimal debt-management strategy for the government in its current form.

Common Trends and Common Cycles in Canadian Sectoral Output

Staff Working Paper 2003-44 Francisco Barillas, Christoph Schleicher
The authors examine evidence of long- and short-run co-movement in Canadian sectoral output data. Their framework builds on a vector-error-correction representation that allows them to test for and compute full-information maximum-likelihood estimates of models with codependent cycle restrictions.

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.

Comparing Alternative Output-Gap Estimators: A Monte Carlo Approach

Staff Working Paper 2003-8 Andrew Rennison
The author evaluates the ability of a variety of output-gap estimators to accurately measure the output gap in a model economy. A small estimated model of the Canadian economy is used to generate artificial data.

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.
