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.

Many important economic variables are subject to revision. This article explains how, when, and why such revisions occur; how revisions to Canadian gross domestic product (GDP) compare with GDP revisions in some other countries; which GDP components are subject to the largest revisions; and how data revisions can affect policy decisions. The author finds that revisions to Canadian GDP tend to be smaller, on average, than those of some other countries, and that among the GDP components, exports and imports are most heavily revised.

Model-based forecasts of important economic variables are part of the range of information considered for monetary policy decision making.

The purpose of this paper is to make a quantitative contribution to the inflation versus price level targeting debate. It considers a policy-maker that can set policy either through an inflation targeting rule or a price level targeting rule to minimize a quadratic loss function using the actual projection model of the Bank of Canada (ToTEM).

Surveys provide direct information on expectations, but only short histories are available at quarterly frequencies or for long-horizon expectations.

How can policy-makers avoid large policy errors when they are uncertain about the true model of the economy?

Suppose that the dynamics of the macroeconomy were given by (partly) random fluctuations between two equilibria: "good" and "bad."

In the interest of better understanding the impact of the Bank of Canada's policy actions on bond and bill yields, Andreou assesses the impact of policy-rate announcements on short and long bonds over the period 1996 to 2004. To aid the analysis, policy actions are decomposed into expected and surprise components. He also examines whether the introduction of fixed announcement dates (FADs) has affected these results, including markets' perceptions. The main finding is that unexpected policy actions by the Bank have a significant effect on market rates at the shorter end of the yield curve, with the effect dissipating as the maturity increases. A second finding, that the impact on longer-term interest rates of a surprise action by the Bank has diminished since the introduction of the FADs, suggests that the Bank's long-term policy goals are well understood and credible.

Policy-makers in the United States over the past 15 to 20 years seem to have been cautious in setting policy: empirical estimates of monetary policy rules such as Taylor's (1993) rule are much less aggressive than those derived from optimizing models.

When it launched a new system for regularly announcing its decisions regarding the overnight rate of interest in December 2000, the Bank of Canada had a number of key objectives in mind. These included reduced uncertainty in financial markets, greater focus on the Canadian rather than the U.S. economic environment, more emphasis on the medium-term perspective of monetary policy, and increased transparency regarding the Bank's interest rate decisions. Evidence to date suggests that all four objectives have been met to a substantial degree. Fixed announcement dates have provided regular opportunities for the Bank to communicate its views on the state of the Canadian economy to the public. This has helped to improve understanding of the broad direction of monetary policy and of the rationale behind the Bank's policy decisions although the decisions themselves are not always fully anticipated.
