Do Mechanical Filters Provide a Good Approximation of Business Cycles? Technical Report No. 78 Alain Guay, Pierre St-Amant In this paper, the authors examine how well the Hodrick-Prescott filter (HP) and the band-pass filter recently proposed by Baxter and King (BK) extract the business-cycle component of macroeconomic time series.

Avoiding the Pitfalls: Can Regime-Switching Tests Detect Bubbles? Staff Working Paper 1996-11 Simon van Norden, Robert Vigfusson Work on testing for bubbles has caused much debate, much of which has focussed on methodology. Monte Carlo simulations reported in Evans (1991) showed that standard tests for unit roots and cointegration frequently reject the presence of bubbles even when such bubbles are present by construction. Evans referred to this problem as the pitfall of testing for bubbles.

Does Inflation Uncertainty Vary with the Level of Inflation? Staff Working Paper 1996-9 Allan Crawford, Marcel Kasumovich The purpose of this study is to test the hypothesis that inflation uncertainty increases at higher levels of inflation. Our analysis is based on the generalized autoregressive conditional heteroscedasticity (GARCH) class of models, which allow the conditional variance of the error term to be time-varying. Since this variance is a proxy for inflation uncertainty, a positive relationship between the conditional variance and inflation would be interpreted as evidence that inflation uncertainty increases with the level of inflation.

Wage and Price Dynamics in Canada Technical Report No. 56 Barry Cozier This paper examines wage and price dynamics in Canada with a view towards testing the implications of a wage-price dynamics, according to which unit labour costs are determined by a wage Phillips curve while prices are set as a markup over unit labour costs. This model is compared to an alternative model in which excess […] Content Type(s): Staff research, Technical reports Topic(s): Inflation and prices JEL Code(s): C, C5, C51, C52, E, E2, E24, E3, E31
Responses of Various Econometric Models to Selected Policy Shocks Technical Report No. 38 Brian O'Reilly, Graydon Paulin, Philip Smith In July, 1982 a seminar was held in Ottawa to compare the responses of nine major econometric models to a previously specified set of shocks to the Canadian economy. At the seminar, which was sponsored by the Bank of Canada and the Department of Finance, participants presented the results of their simulations and discussed the […] Content Type(s): Staff research, Technical reports Topic(s): Economic models JEL Code(s): C, C5, C52, E, E1, E17
