Empirically, how much of the loss of GDP is recovered after a recession?
The question arises again today: after the recession caused by the coronavirus, how much of the loss in GDP level during a recession is recovered after the recession? We know that in certain sectors (tourism, transport, etc.), the loss of revenues is largely irreversible. We also know that a recession has lasting negative effects on growth (capital losses, increased debt). When we look at the 2008-2009 recession, we see that the portion of the loss in GDP levels that was never recovered after the recession is empirically, and surprisingly so: 100% in the United States; 100% in the euro zone; 0% in China.
