Speculative Behaviour, Regime-Switching and Stock Market Crashes Staff Working Paper 1996-13 Simon van Norden, Huntley Schaller This paper uses regime-switching econometrics to study stock market crashes and to explore the ability of two very different economic explanations to account for historical crashes. The first explanation is based on historical accounts of "manias and panics."

The Commodity-Price Cycle and Regional Economic Performance in Canada Staff Working Paper 1996-12 Mario Lefebvre, Stephen S. Poloz This paper attempts to provide one interpretation of the broad regional economic history of Canada since the early 1970s. As the title of the paper suggests, we believe that, to a significant degree, regional diversity in economic performance reflects movements in Canada's terms of trade, which very frequently are tied to developments in world commodity markets.

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.

Unit-Root Tests and Excess Returns Staff Working Paper 1996-10 Marie-Josée Godbout, Simon van Norden Several recent papers have presented evidence from foreign exchange and other markets suggesting that the log of excess returns can be characterized as first-order integrated processes (I(1)). This contrasts sharply with the "conventional" wisdom that log prices are integrated of order one I(1) and that log returns should therefore be integrated of order zero I(0), and even more sharply with the view that past returns have no ability to predict future returns (weak market efficiency).

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.

Interpreting Money-Supply and Interest-Rate Shocks as Monetary-Policy Shocks Staff Working Paper 1996-8 Marcel Kasumovich In this paper two shocks are analysed using Canadian data: a money-supply shock ("M-shock") and an interest-rate shock ("R-shock"). Money-supply shocks are derived using long-run restrictions based on long-run propositions of monetary theory. Thus, an M-shock is represented by an orthogonalized innovation in the trend shared by money and prices.

Excess Volatility and Speculative Bubbles in the Canadian Dollar: Real or Imagined? Technical Report No. 76 John Murray, Simon van Norden, Robert Vigfusson Greater intervention by the public sector is often proposed as a solution to the increased speculation and excessive price volatility thought to characterize today's competitive world financial system.

An Econometric Examination of the Trend Unemployment Rate in Canada Staff Working Paper 1996-7 Denise Côté, Doug Hostland This paper attempts to identify the trend unemployment rate, an empirical concept, using cointegration theory. The authors examine whether there is a cointegrating relationship between the observed unemployment rate and various structural factors, focussing neither on the non-accelerating-inflation rate of unemployment (NAIRU) nor on the natural rate of unemployment, but rather on the trend unemployment rate, which they define in terms of cointegration.

The Bank of Canada's New Quarterly Projection Model, Part 3. The Dynamic Model: QPM Technical Report No. 75 Donald Coletti, Benjamin Hunt, David Rose, Robert Tetlow The Bank of Canada's new Quarterly Projection Model, QPM, combines the short-term dynamic properties necessary to support regular economic projections with the consistent behavioural structure necessary for policy analysis.

Provincial Credit Ratings in Canada: An Ordered Probit Analysis Staff Working Paper 1996-6 Stella Cheung The author estimates the relationship between the provincial credit ratings, as assessed by Standard & Poor's, and a number of economic variables, using the ordered probit methodology. All the variables in her estimation prove to be significant. In particular, she finds that downgrades take place at almost the same speed at different levels of the debt-to-GDP ratio, based on a pooled sample of nine provinces.
