Why is investment spending viewed as an injection into the circular flow?

Savings and investment

Marginal decisions to save reduce the flow of income in the economy because saving is a withdrawal out of the circular flow. However, firms also purchase capital goods, such as machinery, from other firms, and this spending is an injection into the circular flow.

How is government spending an injection?

Government spending is an injection because money is added to the economy which can be used by households to acquire more goods and services. Businesses use the money to expand their operations by purchasing more factors of production.

What is an injection into the circular flow of income?

Injection means the introduction of income into the flow. When households and firms borrow savings, they constitute injections. Injections increase the flow of income. Injections can take the forms of investment, government spending and exports.

How do money that leaked as savings return to the circular flow?

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. Government taxes leak out of the circular flow model, and then government spending injects them back into the economy.

What happens if injections are less than leakages?

If injections and leakages are equal, incomes will be constant; if injections exceed leakages, incomes rise over time; and if leakages exceed injections, incomes fall.

What happens if injections exceed withdrawals?

If injections are greater than withdrawals, Y will increase. As Y increases, S, T & M will also increase, as households will save more, pay more tax and buy more goods from abroad. Y will continue to rise until injections and withdrawals are equal.

How do injections increase GDP?

The fiscal multiplier effect occurs when an initial injection into the economy causes a bigger final increase in national income. For example, if the government increased spending by £1 billion but this caused real GDP to increase by a total of £1.7 billion, then the multiplier would have a value of 1.7.

What is leakage money?

In economics, a leakage is a diversion of funds from some iterative process. … In practice, though, cash leakages occur in the form of sums of money borrowed from banks but not re-deposited, and in the form of funds deposited in banks but not lent out. Cash leakage, in this case, lowers the ability of credit creation.

How does investment affect national income?

An increase in investment raises aggregate demand. National income and employment will rise until equilibrium is restored, i.e. where savings = investment. A decrease in investment has the opposite effect. However, national income will change by more than the change in investment.

Does investment have a positive or negative effect in aggregate consumption?

Investment often peaks earlier than GDP, triggering a negative income-consumption multiplier, thus prompting a new recessionary direction.

Why does investment increase aggregate demand?

The initial increase in investment causes a rise in output and so people gain more income, which is then spent causing a further rise in AD. With a strong multiplier effect, there may be a bigger increase in AD in the long-term.
