This paper examines the implications of changes in economic behaviour for simple inflation-forecast–based monetary rules of the type currently used at two inflation-targeting central banks. Three types of changes in economic behaviour are considered, changes that are motivated by developments in monetary and fiscal policy in the 1990s: changes in monetary policy credibility, changes in […]

This paper studies the implications of certain kinds of uncertainty for monetary policy. It first describes the optimum policy rule in a simple model of the transmission mechanism as in Ball and Svensson.

An important challenge facing central banks is making decisions under uncertainty about the dynamic effects of monetary policy actions. The authors stress the importance of explicitly recognizing uncertainty about the transmission mechanism when formulating policy advice. They argue that one way to manage monetary policy under uncertainty is to draw on both an output-gap paradigm […]

Canada's economic performance in the first half of the 1990s was adversely affected by high premiums in interest rates that were brought on by political and economic uncertainties.

The purpose of this study is to test the hypothesis that inflation uncertainty increases at higher levels of inflation. Our analysis is based on the generalized autoregressive conditional heteroscedasticity (GARCH) class of models, which allow the conditional variance of the error term to be time-varying. Since this variance is a proxy for inflation uncertainty, a positive relationship between the conditional variance and inflation would be interpreted as evidence that inflation uncertainty increases with the level of inflation.

This report shows that extreme conditions and volatility in markets are much more likely to result from systematic policy errors in gauging and responding to inflationary pressures in an economy than from unfortunate random shocks. We describe a simple model that incorporates the key features of the policy control process. We use two versions of […]

This paper analyzes the dynamic behaviour of a country's economy under different policy regimes, by examining the cyclical effects that occur when certain intermediate macroeconomic targets are adopted. To highlight the differences in the adjustment paths that result, the study deliberately limits policy choice: either money supply or nominal income as targets, and either real […]
