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.

The author explores the role that Taylor-type rules can play in monetary policy, given the degree of uncertainty in the economy. The optimal rule is derived from a simple infinite-horizon model of the monetary transmission mechanism, with only additive uncertainty.

In this report, the authors examine and compare twelve private and public sector models of the Canadian economy with respect to their paradigm, structure, and dynamic properties. These open-economy models can be grouped into two economic paradigms.

The benefits of transparency—the outcome of the measures taken by the central bank to allow financial markets and economic agents to understand the factors it takes into account in formulating monetary policy—are now widely recognized. These benefits include smoother implementation of monetary policy and increased effectiveness as markets improve their ability to anticipate the Bank's policy decisions and account for them in their operations. How interest rates respond to the publication of macroeconomic data depends on the degree of transparency in monetary policy, as the rates will rise or fall as a reflection of the market's revised expectations. Before the Bank of Canada adopted initiatives to improve transparency, such as the inflation-control targets, the semi-annual publication of the Monetary Policy Report and Updates, and the fixed announcement dates, changes to the overnight rate created some volatility in interest rates, and publishing Canadian macroeconomic data did not appear to have a major impact on rates. This article shows how the Bank of Canada's steps towards greater transparency have increased the impact of Canadian data on short-term interest rates and have improved financial markets' understanding of how monetary policy decisions are taken.

In this report, we evaluate several simple monetary policy rules in twelve private and public sector models of the Canadian economy. Our results indicate that none of the simple policy rules we examined is robust to model uncertainty, in that no single rule performs well in all models.

We develop an equilibrium model of the monetary policy transmission mechanism that highlights information frictions in the market for money and search frictions in the market for labour.

Central banks must cope with considerable uncertainty about what will happen in the economy when formulating monetary policy. This article describes the different types of uncertainty that arise and looks at examples of uncertainty that the Bank has recently encountered. It then reviews the strategies employed by the Bank to deal with this problem. The other articles in this special issue focus on three of these major strategies.
