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.

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.
