• 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.

• Structural Inflation Models with Real Wage Rigidities: The Case of Canada

  Staff Working Paper 2009-21 Jean-Marie Dufour, Lynda Khalaf, Maral Kichian

  Real wage rigidities have recently been proposed as a way of building intrinsic persistence in inflation within the context of New Keynesian Phillips Curves. Using two recent illustrative structural models, we evaluate empirically the importance of real wage rigidities in the data and the extent to which such models provide useful information regarding price stickiness.

• Structural Multi-Equation Macroeconomic Models: Identification-Robust Estimation and Fit

  Staff Working Paper 2009-19 Jean-Marie Dufour, Lynda Khalaf, Maral Kichian

  Weak identification is likely to be prevalent in multi-equation macroeconomic models such as in dynamic stochastic general equilibrium setups. Identification difficulties cause the breakdown of standard asymptotic procedures, making inference unreliable.

• Assessing Indexation-Based Calvo Inflation Models

  Staff Working Paper 2009-7 Jean-Marie Dufour, Lynda Khalaf, Maral Kichian

  Using identification-robust methods, the authors estimate and evaluate for Canada and the United States various classes of inflation equations based on generalized structural Calvo-type models. The models allow for different forms of frictions and vary in their assumptions regarding the type of price indexation adopted by firms.
