We use Canadian home scanner data to study household food inflation rates during periods of low and high inflation. We find that during the post-pandemic surge in inflation, the actual inflation rates experienced by different households varied more widely. Low-income households faced higher...

Was the episode of high inflation in the Philippines in 2022 driven primarily by supply or demand factors? How did the relative contributions of supply and demand evolve over time? This study adopts the methodology proposed by Shapiro (2022) and Shapiro (2023) to disaggregate Philippine...
