The Keen Model [technical]

I know Steve Keen has taken criticism for his projection that the Australian property market would collapse in 2008 but his reconciliation of MMT, where the sum of all sectoral balances must equal zero, with his Monetary Circuit Theory, where Effective Demand = GDP + change in Debt, is brilliant.

For those who struggle with the terminology:
Ex ante = before the event
Post ante = after the event
Endogenous money simply means banks expand and contract the money supply as customers borrow and repay loans. See Wikipedia for a more detailed explanation.
