Partial exposition of Samuelson's Accelerator Model to conform with the Simple Model 7.3 in the Macroeconomics Book, based on MIT D memo D-1761 by Low and Mass 1973 See also more complete version IM-177550
This model
shows the basic functioning and dynamics of a 'modern monetary system'.
The non-government
sectors, consisting of the private and foreign sectors initial y starts with
zero currency units. It is important to realize that after creating a new currency the government
must first spend currency units into the economy before they can be used:
without currency units the private sector could not even pay taxes! A government
that has its own freely floating currency can create a much money as it wants.
It does not need tax receipts to finance its spending, and any money it spends into
the economy above that collected in taxes represents income for the private
sector. The model show that the government initially created 9 trillion money units,
but spent only six trillion into the economy. The six trillion showed up as a government
deficit but as wealth in the non-government sector.
Since the government
can create as many money units as it wishes and transfer them to
the private sector to ensure an adequate
level of demand in the in the economy, austerity is unnecessary: money is available,
though real resource may be scarce. This also shows that the government can
contribute actively towards the creation of prosperity.
Please note that this model was originally
created by Gene Bellinger, IM 3206, from which this version was cloned.

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:
