95/ so far my (quite shallow) understanding is that these “accounting models” model flows of money. With the basic premise that money has to come from somewhere and go somewhere. Or more accounting-wise that a subtraction one place has to lead to an addition of equal size (possibly the sum of multiple additions) somewhere else.
This relates to the idea that MMT presents, which Wynne Godley also seems to have supported and Richard Vague (above article and TED talk), that a deficit for the state necessitates a surplus somewhere else. Found this graph from Godley using his “sectoral financial balances” framework, depicting the US economy. This graph is very similar (perhaps identical?) to what Vague shows in his TED talk. They both show what seems to be an inverse relationship between a public deficit and a private surplus.
