Abstract

Food prices are salient for households’ inflation perceptions and expectations at both the micro and macro levels. UK survey data indicate over 60% of households report food prices as very important for perceived inflation. These households exhibit a stronger correlation between perceived and expected inflation, reflecting backward-looking expectations. An SVAR with aggregate data shows food-price shocks generate larger and more persistent movements in expectations than “representative” inflation shocks. Finally, embedding behavioural expectations in a New Keynesian model, we find that, following a food-price shock, welfare losses are mitigated when monetary policy responds to households’ inflation expectations, even if they overreact.
