First, thanks to this author for an edifying article--though it does (unless I somehow missed it) curiously leave out 'printing money' for the central bank to use to purchase (a portion of) the debt of the central government--its famous role as 'lender of last resort'. I thought the author (or other readers) might find interesting an alternative paradigm I have developed for supplying an economy with money (as currency: money created by the central bank). The supply of that money would become self-regulating and would make the economy self-regulating.
It combines QE--creating money as needed without involving debt in the process--with 'closing the monetary loop', which occurs in the other form of creating money when loans are repaid to banks. When a central bank creates money currently, there is no fixed mechanism for any of it be returned to its place of origin. That is why 'printing money' is so dangerous in terms of potential price inflation.
