Greedflation - companies exploiting a high inflation environment to raise prices relatively more than costs - has grabbed attention and headlines in economics commentary, but the evidence to prove definitively whether it took place on a wide scale in the post-COVID period is not conclusive. This week, we chat with our academic partner Alberto Cavallo, professor at Harvard Business School and co-founder of PriceStats, about a new working paper in which he and his co-authors take a deep dive into cost and pricing dynamics during the pandemic years. They employ unique data sets and analysis to determine whether, where and when excessive mark-ups on goods prices took place along the supply chains during the high inflation years of 2021-2023.
