• Household Food Inflation in Canada

  Staff Working Paper 2024-33 Olena Kostyshyna, Maude Ouellet

  We study food inflation rates for Canadian households during periods of low and high inflation from 2012Q4 to 2023Q4. Households experienced more varied inflation rates during the recent high inflation. Cumulative food inflation has been 2.2 percentage points higher for lower-income households than for highest-income households since the inflation surge.

  Staff Working Paper 2024-14 Olena Kostyshyna, Tolga Özden, Yang Zhang

  We quantitively assess the risks of a wage-price spiral occurring in Canada over history. We find the risk of a wage-price spiral increases when the inflation expectations become unanchored and the credibility of central banks declines.

• Pricing behaviour and inflation during the COVID-19 pandemic: Insights from consumer prices microdata

  Staff Analytical Note 2024-6 Olga Bilyk, Mikael Khan, Olena Kostyshyna

  Using the microdata underlying the Canadian consumer price index, we study how often and by how much firms changed their prices during the COVID-19 pandemic. We find that the surge in inflation was mainly associated with retailers raising prices much more often than before. We also find that more recently, corporate price-setting behaviour appears to be approaching pre-pandemic norms.
