Circular flow - open economy with government
If you would prefer to view this interaction in a new web window, then please follow the link below:
Explain, using a diagram, the circular flow of income in an open economy with government and financial markets, referring to leakages/ withdrawals (savings, taxes and import revenue) and injections (investment, government revenue and export revenue).
Remember that equilibrium is when the circular flow is stable (not growing and not shrinking) and is when:
Injections = Withdrawals
Investment + Gov. Spending + Export Revenue = Saving + Taxes + Import spending
I+G+X = S + T + M
NB It is not necessary for one component to equal its counterpart (eg saving does not have to equal investment) equilibrium is when the whole LHA equals the whole RHS.
NB if I+G+X > S + T + M the economy (Flow) is increasing
NB if I+G+X < S + T + M the economy (Flow) is decreasing
Remember: Y=E=Q Must be true at all times
(because we are measuring the same thing in three different ways)
