MMT incorporates the concept and emphasises the importance of the sector financial balances model of aggregate demand. It is a simple concept. The public sector, the private sector and foreign sector surpluses/deficits net to zero in any measured time period.
It causes neo-liberal types some problems. They probably do not like the idea of a public sector deficit being a necessary condition for a private sector surplus. They would like to pretend that the public account and private sector can be in strong surplus simultaneously. That’s impossible except for those countries who export much more than they import. So I wouldn’t expect to see three sector graphs offered up for public consumption by the mainstream media any time soon.
They are pretty good indicators of how the share market might perform though so naturally they can’t be totally ignored!
For what it’s worth I would agree that its a good time to buy shares. Watch that black line (the private sector) in the first graph. When it bottoms out, it will be a good time to sell!
If previous experience is anything to go by, the indicators will be completely misinterpreted for popular consumption. The reduced future public sector deficit will be hailed as a great success by various western governments. There won’t be any mention that this will mean the private sector will be overstretched. There won’t be any warnings of the next slump to come. The experts will be telling investors not to panic and prophesising soft landings etc. You’ll know what I mean. You’ve heard it all before!
PS If anyone does really well from this advice I’m not too proud to accept tokens of appreciation!
Modern Monetary Theory: Real Economics 
The government should do helicopter money and then counter the resulting inflation with a land value tax (high enough e.g 90%.) I have a question, how much money would need to be printed to screw over the rentiers and keep prices stable?
