What are injections and leakages in the circular flow model?
What are injections and leakages in the circular flow model?
Injections into the economy include investment, government purchases and exports while leakages include savings, taxes and imports. Savings leaks out to borrowers as it goes through the banking system, and borrowers use the money to buy goods and services, which then injects the money back into the circular flow.
What is an injection in economics?
Injections are variables in an economy that add to the circular flow of income, and include investment (I) government spending (G) and exports (X).
What is the formula for injection in economics?
Most importantly, when aggregate expenditures equal aggregate production (Y = AE), then injections are necessarily equal to leakages S + T + M = I + G + X.
What is the difference between leakage and injection?
Injections are the introduction of income into the flow, such as additions to investment, government expenditure and exports. Leakages are the withdrawal of income from the flow, such as savings, taxation and imports.
What are the two basic principles of circular flow of income?

Which is an example of an injection in the circular flow?
Injections into the circular flow Injections are variables in an economy that add to the circular flow of income, and include investment (I) government spending (G) and exports (X).
How are leakages and injections related in the circular flow model?
One half of the injections-leakages model is injections, which are non-consumption expenditures on aggregate production. The three injections are investment expenditures, government purchases, and exports. These are termed injections because they are “injected” into the core circular flow of consumption, production, and income.
