The author provides a non-technical explanation of the role played by the exchange rate in Canada's inflation-targeting monetary policy.

An essential element of the Bank of Canada's inflation-targeting framework is a floating exchange rate that is free to adjust in response to shocks that affect the Canadian and world economies. This floating rate plays an important role in the transmission mechanism for monetary policy. A practical question is how the Bank of Canada incorporates currency movements into the monetary policy decision-making process. Only after determining the cause and persistence of exchange rate change, and its likely net effect on aggregate demand, can the Bank decide on the appropriate policy response to keep inflation low, stable, and predictable. Ragan reviews the need to target inflation and the transmission mechanism for monetary policy, including the role of the exchange rate, before describing two types of exchange rate movements and their implications for monetary policy.

The issue addressed in this article is the extent to which monetary policy in Canada should respond to asset-price bubbles. The article concludes that maintaining low and stable consumer price inflation is the best contribution that monetary policy can make to promoting economic and financial stability, even when the economy experiences asset-price bubbles. In extreme circumstances—when an asset-price bubble is well identified and likely to have significant costs to the economy when it bursts—monetary policy might better maintain low and stable consumer price inflation by leaning against a particular bubble even though it may mean that inflation deviates temporarily from its target. Such a strategy might reduce the risk that a crash in asset prices could lead to a recession and to inflation markedly below target in the longer run. The circumstances where this strategy is possible will be rare because economists are far from being able to determine consistently and reliably when leaning against a particular bubble is likely to do more harm than good. Housing-price bubbles should be a greater concern for Canadian monetary policy than equity-price bubbles, since rising housing prices are more likely to reflect excessively easy domestic credit conditions than are equity prices, which are largely determined in global markets.

In two recent papers, Jensen (2002) and Walsh (2003), using a hybrid New Keynesian model, demonstrate that a regime that targets either nominal income growth or the change in the output gap can effectively replicate the outcome under commitment and hence reduce the size of the stabilization bias.

The authors compute welfare-maximizing Taylor rules in a dynamic general-equilibrium model of a small open economy.

The authors evaluate whether an assortment of simple rules could improve how the Bank of Canada implements its inflation-targeting monetary policy. They focus on measuring the correlation between the deviations of inflation from the target and the lagged deviations of rule recommendations from the actual policy interest rate.

Inflation targeting, a stable macroeconomic environment, and an average growth rate for potential output that is not expected to vary much in the next several years all help households, businesses, and governments in their medium-term economic and financial planning. Several simple rules of thumb can be usefully employed in this planning. Specifically, inflation targeting has maintained most major measures of inflation quite close to the target midpoint on average over a number of years. Combined with a clear fiscal framework, this has contributed to a more stable macroeconomic environment in which output varies less around its potential level. Potential output growth is expected to average around 3 per cent over the next several years. In light of these factors and historical relationships, labour income, profits, and consumer spending will likely grow, on average, by about 5 per cent over the medium term. Real and nominal long-term interest rates should also continue to be stable, with real 30-year yields varying around 3.5 or 4.0 per cent, and nominal yields varying around 5.5 or 6.0 per cent.

This paper shows that if the Bank of Canada is optimally adjusting its monetary policy instrument in response to inflation indicators to target 2 per cent inflation at a two-year horizon, then deviations of inflation from 2 per cent represent the Bank's forecast errors, and should be uncorrelated with its information set, which includes two-year lagged values of the instrument and the indicators. Positive or negative correlations are evidence of systematic errors in monetary policy.

Over the last 10 years, the level of inflation has been much lower than in the previous two decades. At the same time, the behaviour of inflation has changed profoundly. By surveying the data and the economic research, the author first examines changes in the variability, growth rates, and behaviour of some of the major macroeconomic variables during the 1980s and 1990s. He then looks at how these changes are linked to a shift in the approach of monetary policy over the period. Lastly, he reviews the economic benefits that these changes have had for Canada.

While the Bank of Canada's inflation-control target is specified in terms of the rate of increase in the total consumer price index, the Bank uses a measure of trend or "core" inflation as a short-term guide for its monetary policy actions. When the inflation targets were renewed in May 2001, the Bank announced that it was adopting a new measure of core inflation. This measure excludes the eight most volatile components of the CPI and adjusts the remaining components for the effect of changes in indirect taxes. In this article, the author discusses the definition of the new measure of core inflation and describes some of its advantages relative to the previous measure. He notes that the new measure has a firmer statistical basis, has a better correspondence with economic theory, and does a better job of predicting future changes in overall inflation. While the new measure has these advantages, the Bank will continue to monitor a broad range of indicators when assessing the likely future path for inflation.
