On the Wedge Between the PPI and CPI Inflation Indicators

Staff working paper 2022-5 Shang-Jin Wei, Yinxi Xie
We find that the CPI and PPI inflation indexes co-moved strongly throughout the late 20th century, but their correlation has fallen substantially since the early 2000s. We offer a structural explanation for this divergence based on the growth of global supply chains since 2000. This finding offers a unique perspective for the future design of optimal monetary policy.

Declining Inflation Persistence in Canada: Causes and Consequences

The persistence of both core and total consumer price index inflation in Canada has declined significantly since the 1980s. In addition to providing up-to-date estimates of inflation persistence, this article examines possible reasons for the decline suggested in the literature. The role played by monetary policy, through its effect on price- and wage-setting behaviour, is distinguished from possible changes to the structure of the economy that are independent of monetary policy. The authors also discuss the implications for monetary policy of low structural persistence in inflation, including the choice of an inflation-targeting regime versus a price-level-targeting regime.

Our Approach to Monetary Policy: Inflation Targeting

Remarks David Dodge Regina Chamber of Commerce Regina, Saskatchewan
This year also marks the 70th anniversary of the creation of the Bank of Canada, and we too have taken the time to celebrate our contributions to Canada. At such times, while it is appropriate to look back and celebrate history and accomplishments, it is also a good opportunity to look forward and think about where we are headed. In this spirit, I'd like to talk to you today about one of our main responsibilities; that is, the conduct of monetary policy.

Central Bank Performance under Inflation Targeting

Gosselin examines and reports on the various factors that contribute to successful inflation targeting. Using a panel of 21 inflation-targeting countries over the period 1990Q1-2007Q2, Gosselin finds that the ability of central banks to hit their targets varies considerably. Some of these differences can be explained by exchange rate fluctuations, fiscal deficits, and differences in financial development. Others are explained by differences in the targeting framework itself and the manner in which it is implemented.

Core inflation over the COVID-19 pandemic

Staff analytical note 2022-17 Mikael Khan, Elyse Sullivan
We assess the usefulness of various measures of core inflation over the COVID-19 pandemic. We find that Cpi-trim and CPI-median provided the best signal of underlying inflation. The favourable performance of these measures stems from their lack of reliance on historical experience, an especially valuable feature in unprecedented times.
