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:
This
paper aims at describing a case where system dynamics modeling was used to evaluate
the effects of information and material supply lead-time variation on sales
contributions margins and operating cash conversion cycle of a commodity export
business. An empirical dynamic model,
loaded with econometric theory of price effect on competitive demand, was used
to describe the input data. The model simulation
outputs proved themselves relevant in analyzing the complex interconnections of
multiple variables affecting the
profitability in a commercial routine, supporting the decision process among
sales managers.
This high-level
simulation model presented by Jay Forrester in his book World Dynamics, simulates
socio-economic-environmental world system. The world Model was created in a
time where pollution and other negative effects of industrialization and
economic growth started to become recognized in 1970. For this exam purpose, we have
rebuilt the model to do some experiments and analyze the results.

This model shows the operation of a simple economy. It demonstrates the effect of changes in the fractional rate of consumption (or the converse the fractional rate of saving.)
In summary, lower rates of consumption (based on production) result in higher rates of production and consumption in the long-run.
