Abstract
We study household‐level food inflation rates during low‐inflation, pandemic and postpandemic inflation surge periods using Canadian homescan data for 2012Q4–2023Q4. Our results about household inflation rates during low inflation are consistent with evidence for the United States (Kaplan and Schulhofer‐Wohl 2017). During the postpandemic inflation surge, we find that the dispersion in household‐level inflation rates increased and that the correlation between household‐level inflation rates and aggregate inflation became stronger. Households shopping more frequently, shopping at more stores or buying more on sale experienced lower food inflation, and households relied more on these strategies to lower their inflation in the high‐inflation period. Consumers substituted more toward lower‐priced products with the postpandemic increase in inflation. Lower‐income households experienced higher food inflation rates. These findings have implications for the welfare costs of inflation. L'inflation alimentaire des ménages au Canada. Nous étudions les taux d'inflation alimentaire à l'échelle des ménages au cours de trois périodes : une période de faible inflation, la pandémie et la flambée inflationniste postpandémique, en utilisant des données canadiennes Homescan du 4e trimestre de 2012 au 4e trimestre de 2023. Nos résultats pour la période de faible inflation sont cohérents avec ceux observés aux États‐Unis (Kaplan et Schulhofer‐Wohl, 2017). Lors de la flambée inflationniste postpandémique, nous constatons une hausse de la dispersion des taux d'inflation entre ménages ainsi qu'un renforcement de la corrélation entre l'inflation agrégée et l'inflation à l'échelle des ménages. Les ménages qui font leurs achats plus fréquemment, visitent plusieurs magasins ou achètent davantage de produits en promotion subissent une inflation alimentaire plus faible. Ces stratégies ont été plus utilisées en période de forte inflation. Les consommateurs se sont davantage tournés vers des produits moins chers lors de la hausse postpandémique de l'inflation. Les ménages à plus faible revenu ont connu des taux d'inflation alimentaire plus élevés. Ces résultats permettent de mieux comprendre les effets de l'inflation sur le bien‐être des ménages.
