Central banks can implement unconventional monetary policy measures to provide additional easing when policy interest rates come close to their lower limit. To date, the international experience with tools such as quantitative easing and negative interest rates has been largely positive. Central banks may also use several such measures simultaneously, with often mutually reinforcing effects. Yet, unconventional tools are also subject to potential limits, and the costs associated with these measures could rise with extensive and prolonged use.

Inflation-targeting frameworks have remained relatively stable over the past few years despite significant challenges, including prolonged low inflation, a large negative commodity price shock and rising financial stability concerns in some economies. The tools used by central banks have, however, evolved substantially. This article provides a survey of the developments in the inflation-targeting frameworks of 10 central banks in advanced economies that correspond to the three research areas of the Bank of Canada’s 2016 renewal: the level of the inflation target, the measurement of core inflation and financial stability considerations in the formulation of monetary policy.

Should monetary policy lean against housing market booms? We approach this question using a small-scale, regime-switching New Keynesian model, where housing market crashes arrive with a logit probability that depends on the level of household debt.

Inflation expectations are a key determinant of actual and future inflation and thus matter for the conduct of monetary policy. We study how firms form their inflation expectations using quarterly firm-level data from the Bank of Canada’s Business Outlook Survey, spanning the 2001 to 2015 period.

We analyze the interaction between committed monetary policy and discretionary fiscal policy in a model with public debt, endogenous government expenditures, distortive taxation and nominal rigidities.

In 2009, the Bank of Canada set its effective lower bound (ELB) at 25 basis points (bps). Given the recent experience of Sweden, Denmark, Switzerland and the euro area with negative interest rates, we examine the economics of negative interest rates and suggest that cash storage costs are the source of a negative lower bound on interest rates.

Forward guidance is one of the policy tools that a central bank can implement if it seeks to provide additional monetary stimulus when it is operating at the effective lower bound (ELB) on interest rates. It became more widely used during and after the global financial crisis.

This paper summarizes the international evidence on the performance of quantitative easing (QE) as a monetary policy tool when conventional policy rates are constrained by the effective lower bound (ELB). A large body of evidence suggests that expanding the central bank’s balance sheet through large-scale asset purchases can provide effective stimulus under the ELB.

Central banks may face challenges in achieving their price stability goals when financial stability risks are present. There is, however, considerable heterogeneity among central banks with respect to how they manage these potential trade-offs.

A key issue in the renewal of the inflation-control agreement is the question of the appropriate level of the inflation target. Many observers have raised concerns that with the reduction in the neutral rate, and the experience of the recent financial crisis, the effective lower bound (ELB) is more likely to be binding in the future if inflation targets remain at 2 per cent.
