Once ideas about how to manage the economy become entrenched, it can take generations to dislodge them. Something big usually has to happen to jolt policy onto a different track. Something like Covid-19. In 2020, when the pandemic hit and economies around the world went into lockdown, policymakers effectively short-circuited the business cycle without thinking twice.
The Great Recession that followed the crash of 2008 had already triggered a rethink. But the overall approach emerged relatively intact. Roughly speaking, that approach placed a priority on curbing inflation and managing the pace of economic growth by adjusting the cost of private borrowing rather than by spending public money.
The pandemic cast those conventions aside around the world. In the new economics, fiscal policy took over from monetary policy. Governments channeled cash directly to households and businesses and ran up record budget deficits. Central banks played a secondary and supportive role—buying up the ballooning government debt and other assets, keeping borrowing costs low, and insisting that this was no time to worry about inflation. While the flight from orthodoxy was most pronounced in the world’s richest countries, versions of this shift played out in emerging markets, too. Even institutions like the IMF, longtime enforcers of the old rules of fiscal prudence, preached the benefits of government stimulus.
In the US, and to a lesser extent in other developed economies, the result has been a much faster recovery than after 2008. That success is opening a new phase in the fight over policy. Lessons have been learned about how to get out of a downturn. Now it’s time to figure out how to manage the boom.
For centuries, theorists have pondered the recurring and inevitable swings that make up the business cycle. According to the traditional laws of the cycle, it should’ve taken years for households to claw their way back from 2020’s sudden collapse in economic activity. Instead, the US government stepped in to insulate them from its worst effects in a way that hadn’t really been tried before: by replacing the wages that millions of newly out-of-work Americans were no longer receiving from employers.
