Inflation turned out to be a defining issue of the
2024 election, but the common story about its cause — covid-era stimulus — is more wrong than right. We should not learn a mistaken lesson.
The culprit is
often identified as the
American Rescue Plan, a $2 trillion stimulus package enacted in March 2021, which followed other relief packages provided in 2020. According to this theory, the government may have meant well, but it put too much money into people’s pockets, drove up demand and unleashed inflation.
This story is intuitively appealing, and it is no surprise it became
a popular narrative with the media. The weight of the evidence, however, suggests that the package had only a modest impact on the path of inflation.
The central cause was the pandemic itself — and the nearly unprecedented supply-side shock it caused, which extended beyond the crisis itself.
Along with Robin Brooks of Brookings and William Murdock of Lazard,
I have parsed a variety of economic data through the arc of the pandemic, including a commonly used measure of demand, supply indicators such as delivery times, and a proxy for how firms manage their inventories.
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.
