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.

The third strategy employed by the Bank when dealing with uncertainty is the consideration of appropriate simple reaction functions or "rules" for the setting of the policy interest rate. Since John Taylor's presentation of his much-discussed rule, research on simple policy rules has exploded. Simple rules have several advantages. In particular, they are easy to construct and communicate and are believed by some to be robust, in the sense of generating good results in a variety of economic models. This article provides an overview of the recent research regarding the usefulness and robustness of simple monetary policy rules, particularly in models of the Canadian economy. It also describes and explains the role of simple rules in the conduct of monetary policy in Canada.

In recent years, there has been a lot of interest in Taylor-type rules. Evidence in the literature suggests that Taylor-type rules are optimal in a number of models and are fairly robust across different models.

This article summarizes the proceedings of a conference hosted by the Bank of Canada in November 1999. Three major themes emerged at the conference. The first concerned uncertainty about the transmission mechanism by which monetary policy affects output and inflation. The second concerned the potential usefulness of monetary aggregates in guiding the economy along a stable non-inflationary growth path. The third was the recent developments in dynamic monetary general-equilibrium models. The work presented suggests that a wide range of models is useful for understanding the various paths by which monetary policy actions might influence the economy.

The effective conduct of monetary policy is complicated by uncertainty about the level of potential output, and thus about the size of the monetary policy response that would be sufficient to achieve the targeted inflation rate. One possible response to such uncertainty is for the monetary authority to "probe," interpreted here as actively using its policy response to learn about the level of potential output.
