Academic research suggests that official CPI figures in the post-pandemic era have not been an accurate reflection of consumer prices. We summarise key findings from a recent study and outline the alternative data sources that can help build a more accurate gauge of inflation.


In this literature review, we discuss the working paper, Inflation with Covid Consumption Baskets by Alberto Cavallo – co-founder of MIT’s Billion Prices Project. The study was first published in June 2020.
