Preparing for crises in a way that does not kill growth

The euro zone, including France, has been hit by a series of crises: subprime crisis (2008-2009), euro-zone crisis (2010-2013), COVID crisis (2020). This will lead companies to prepare for the next crisis. The risk is that companies may prepare for crises in a way that destroys growth. For instance, they accumulate huge cash reserves, which protects them in the event of a recession, but kills growth as those cash reserves could have been invested. They could also opt for short-term employment contracts, which has not been the case since the subprime crisis. So there is a need to think up methods to cope with future crises that do not harm growth. The answer could involve f or example: The issuance of subordinated bonds that automatically convert into equity in recessions; The guarantee that short-time working schemes will be implemented in the event of a recession in the future.
