The results show that supply-chain variables directly accounted for 79 percent of the rise in underlying inflation in 2021. These effects then continued into 2022, with ongoing supply issues directly explaining 60 percent of the rise in inflation that year. The rest was more than accounted for by spillovers from the 2021 supply-driven inflation. All of which leaves only a modest role for demand-driven effects like the covid relief package.
Why did these effects play out over such a long time?
