Market Expectations and Option Prices: Evidence for the Can$/US$ Exchange Rate
Security prices contain valuable information that can be used to make a wide variety of economic decisions. To extract this information, a model is required that relates market prices to the desired information, and that ideally can be implemented using timely and low-cost methods. -

Monetary Policy Rules in an Uncertain Environment
This article examines recent research on the influence of various forms of economic uncertainty on the performance of different classes of monetary policy rules: from simple rules to fully optimal monetary policy under commitment. The authors explain why uncertainty matters in the design of monetary policy rules and provide quantitative examples from the recent literature. They also present results for several policy rules in ToTEM, the Bank of Canada's main model for projection and analysis, including rules that respond to price level, rather than to inflation. -
What Drives Exchange Rates? New Evidence from a Panel of U.S. Dollar Bilateral Exchange Rates
We use a novel approach to identify economic developments that drive exchange rates in the long run. Using a panel of six quarterly U.S. bilateral real exchange rates – Australia, Canada, the euro, Japan, New Zealand and the United Kingdom – over the 1980-2007 period, a dynamic factor model points to two common factors. -
Estimating DSGE-Model-Consistent Trends for Use in Forecasting
The workhorse DSGE model used for monetary policy evaluation is designed to capture business cycle fluctuations in an optimization-based format. It is commonplace to log-linearize models and express them with variables in deviation-from-steady-state format. -
A Consistent Test for Multivariate Conditional Distributions
We propose a new test for a multivariate parametric conditional distribution of a vector of variables yt given a conditional vector xt. -
Real Time Detection of Structural Breaks in GARCH Models
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. -

Understanding Corporate Bond Spreads Using Credit Default Swaps
Corporate bond spreads worldwide have widened markedly since the beginning of the credit crisis in 2007. This article examines default and liquidity risk–the main components of the corporate bond spread–for Canadian firms that issue bonds in the U.S. market, focusing in particular on their evolution during the credit crisis. They find that, during this period, the liquidity component increased more for speculative-grade bonds than it did for investment-grade bonds, consistent with a "flight-to-quality" phenomenon. An important implication of their results for policy-makers seeking to address problems in credit markets is that the liquidity risk in corporate spreads for investment and speculative bonds behaves differently than the default risk, especially during crisis episodes. -
Structural Inflation Models with Real Wage Rigidities: The Case of Canada
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
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.
