Governments save economies. Never let a mainstream economist tell you that government intervention is undesirable and that the ‘market’ will sort things out. Never let them tell you that large-scale government bond purchases by central banks lead to inflation. Never let them tell you that the government, when properly run, can run out of money. There is unlimited amounts of public purchasing capacity. The art is when to apply it and how much to release. That can only be determined by the behaviour of the non-government spending and saving and the state of idle capacity. It can never be determined by some arbitrary public debt threshold or deficit size. And the central bank can always buy however much debt they choose. At present the ECB is buying heaps and keeping the Member States solvent. That is not its state role but given there is no other institution in the Eurozone that can serve the fiscal function effectively and ‘safely’, it has to do that. Otherwise, the monetary union would quickly dissolve. I would take their bond buying programs further and write off all the debt they purchase. Immediately. Go on. Just type some zeros where they have recorded large positive Member State debt holdings. That would be something good to do in a terrible situation.
