This model illustrates the current practice and consequences of government spending. Following the
direction of the arrows from right to left the model shows the following sequence
based on current practice:
Government
Spending at a certain point leads to spending in excess of tax receipts. This
will automatically lead to the issue of treasuries in the belief that the excess
spending must be financed by borrowing (although the government has the capacity
to create money). This in turn will
increase the national debt.
Consequences that follow from this practice:
1) That national
debt increases whenever the government spends in excess of tax receipts.
2) That the
government must pay interest on the debt issued, which in turn increases and
reinforces the need for government spending.
3) That the
interest paid on treasuries will increase private sector income.
There is an
alternative view, supported by Modern Monetary Theory, of how government spending
can proceed. Please see this Insight:
Goodwin cycle IM-2010 with debt and taxes added, modified from Steve Keen's illustration of Hyman Minsky's Financial Instability Hypothesis "stability begets instability". This can be extended by adding the Ponzi effect of borrowing for speculative investment.
Clusters of interacting methods for improving health services network design and delivery. Includes Forrester quotes on statistical vs SD methods and the Modeller's dilemma. Simplified version of IM-14982 combined with IM-17598 and IM-9773
This model simulates the economics of buying a home. It was created to compare buying a home against using investment returns to pay for rent. According to Micheal Finke, house prices typically run 20x monthly rental rates.
Try cloning this insight, setting the parameter values for real-world scenarios, and then running sensitivity analysis (see tools) to determine the likely wealth outcomes. Compare buying a home to renting. Note that each run will keep the parameters the same while simulating market volatility.
