Direct reserve emission by the central bank.
In practice, the central bank can just give some reserve to the governement account.
Personnally, I'd rather give the money to the governement like we did in the keynesian golden age, because it fuels the development of infrastructures, housing and social security. And at our point in history, it could be used to transition to a sustainable society. But that's because I don't trust the market on this, I'm kind of a socialist.

This is such a failure (esp. in the EU) I don't see how I could disagree with you on this.
Share market jumped, retailers rolled out significant sales. People bought TVs.
It's more likely that negative interest rates will be passed onto consumer bank accounts by elmininating cash.
