Covid-19: Has the Time Come for Mainstream Macroeconomics to Rehabilitate Money Printing?

The expenditure necessary to avoid the Covid-19 health crisis turning into a long-lasting deep recession is enormous and raises the issue of how it should be financed: through new debt, or monetization? Monetization - defined as the financing of public expenditure through money creation by the central bank without being reimbursed by the government - has long been rejected by mainstream macroeconomics. Axelle Arquié (EconPol Europe, CEPII), Jérôme Héricourt (EconPol Europe, Université de Lille & CEPII) and Fabien Tripier (EconPol Europe, Université Paris-Saclay (Evry) & CEPII) analyze in detail some recent theoretical arguments of mainstream macroeconomics to rehabilitate monetization.
