The dominant view of inflation holds that it is macroeconomic in origin and must always be tackled with macroeconomic tightening. In contrast, we argue that the US COVID-19 inflation is predominantly a sellers’ inflation that derives from microeconomic origins, namely the ability of firms with market power to hike prices. Such firms are price makers, but they only engage in price hikes if they expect their competitors to do the same. This requires an implicit agreement which can be coordinated by sector-wide cost shocks and supply bottlenecks. We review the long-standing literature on price-setting in concentrated markets and survey earnings calls and compile firm-level data to derive a three-stage heuristic of the inflationary process: (1) Rising prices in systemically significant upstream sectors due to commodity market dynamics or bottlenecks create windfall profits and provide an impulse for further price hikes. (2) To protect profit margins from rising costs, downstream sectors propagate, or in cases of temporary monopolies due to bottlenecks, amplify price pressures. (3) Labor responds by trying to fend off real wage declines in the conflict stage. We argue that such sellers’ inflation generates a general price rise which may be transitory, but can also lead to self-sustaining inflationary spirals under certain conditions. Policy should aim to contain price hikes at the impulse stage to prevent inflation from the onset.

Paul Krugman apparently called this article "truly stupid". I can think of no higher praise.
President Truman was aware of the risks of ending price controls. On 30 October 1945, he warned that after the first world war, the US had “simply pulled off the few controls that had been established, and let nature take its course”. And he urged, “The result should stand as a lesson to all of us. A dizzy upward spiral of wages and the cost of living ended in the crash of 1920 – a crash that spread bankruptcy and foreclosure and unemployment throughout the Nation.” Nevertheless, price controls were pulled in 1946, again triggering inflation and a boom-bust cycle.
Today, there is once more a choice between tolerating the ongoing explosion of profits that drives up prices or tailored controls on carefully selected prices. Price controls would buy time to deal with bottlenecks that will continue as long as the pandemic prevails. Strategic price controls could also contribute to the monetary stability needed to mobilize public investments towards economic resilience, climate change mitigation and carbon-neutrality. The cost of waiting for inflation to go away is high.
