Governments spent trillions of dollars in 2020 tackling the pandemic while propping up businesses and households. But the unprecedented expenditure has awakened real concern about such high levels of borrowing. World Bank Chief Economist Carmen Reinhart says we should worry about winning the war first and how to pay for it later. She joins host Stephanie Flanders to discuss why policymakers shouldn't confuse rebound with recovery, and how a slow rollout of vaccines may cut global growth in half this year. 

Flanders also speaks with Bloomberg Economics’ Jamie Rush about the real cost of all that borrowing. And Bloomberg Businessweek Economics Editor Peter Coy looks at the parallels between the current crisis and that of the 1920s, and how this decade could be just as roaring.
