Study Notes

Relationship Between Investment and Interest Rate

Investment is the second component of expenditure in an economy, considered highly volatile.
Investment's funding cost is directly tied to interest rates.
Investment decisions hinge on the expected rate of return, calculated after deducting all costs.
Investment viability occurs when the expected rate of return (r) exceeds or equals the interest rate (i).
The investment demand curve slopes downward, reflecting an inverse relationship between interest rates and investment levels.
Factors influencing the investment demand curve include:
- Variations in acquisition, maintenance, and operational costs.
- Shifts in business tax policies.
- Technological advancements.
- Existing capital stock levels.
- Planned inventory adjustments.
- Anticipated future economic conditions.

Factors Contributing to Investment Volatility

Fluctuations in economic expectations.
Durability of capital goods.
Irregular innovation patterns.
Variations in profitability.

Consumption vs Investment Fluctuations

Investment can theoretically reach zero during recessions; consumption cannot.
Consumption maintains a positive level to meet basic needs.
Consumption displays lower volatility compared to investment due to the necessity of basic consumption.

Multiplier Effect

The multiplier effect illustrates the connection between expenditure and income, highlighting how expenditure changes multiply income and GDP.
The multiplier is calculated by dividing the change in real GDP by the initial spending change.
The repeated nature of income and expenditure within the economy drives the multiplier effect.
Each spending action generates income for those involved in production and distribution.
Individuals spend a portion of their income, re-injecting it into the economy to generate further income and expenditure.
MPC (marginal propensity to consume) represents the proportion of additional income spent on consumption.
The multiplier effect explains how a spending increase significantly elevates national income.

Numerical Example

Economy A's MPC is 0.8.
Initial spending of 100 generates 100 in seller income.
20 of the income is saved, creating a leakage from the circular flow.
80 of the income is re-spent, generating 80 in income for the next seller.
This repeated spending and income generation cycles amplify total economic income.

Multiplier Effect (updated)

Initial Increase in Spending: A rise in spending triggers a cascading effect, increasing income and GDP.
Multiplier Process: Subsequent rounds of spending generate additional income, which is subsequently spent, driving further increases in income and expenditure.
Marginal Propensity to Consume (MPC): The proportion of extra income dedicated to consumption.
Marginal Propensity to Save (MPS): The fraction of additional income set aside as savings.
Multiplier Formula:
- Multiplier = 1 / (1 - MPC)
- Multiplier = 1 / MPS
Higher MPC, Higher Multiplier: A higher MPC leads to increased spending, boosting the multiplier effect.
Lower MPC, Lower Multiplier: A lower MPC results in more savings, decreasing the multiplier effect.
Example: An MPC of 0.8 yields a multiplier of 5. With an initial $100 spending increase, total income and GDP grow by $500.
Leakages: Factors like savings, taxes, and imports reduce the multiplier effect's impact.
Savings: Saved money does not propel further income increases.
Imports: Money spent on foreign goods does not contribute to domestic income.
Taxes: Income taxes diminish disposable income, and, thus, reduce the multiplier effect.
Real-World Considerations: The multiplier is often lower than the theoretical potential due to:
- Diverse MPCs within the population.
- Savings decisions.
- Import purchases.
- Tax obligations.
- Inflationary pressures.
Reduction in Spending: Decreased spending generates a multiplied decline in GDP and income.
Importance for Economic Policy: Understanding the multiplier is pivotal for crafting effective economic stimulus packages, where government spending boosts demand and income.
- Government spending can stimulate demand and increase income.
- Cash transfers can enhance consumer spending.
- Spending targeted toward lower-income individuals maximizes the multiplier effect.
Benefits of Spending on Local Businesses: Supporting local businesses magnifies the multiplier's positive effect on the local economy.

Other Key Points

Zakat and Sadaka: Islamic charitable practices bolster economic growth by redistributing wealth to those with higher MPCs, thereby maximizing the multiplier.
Economic Circle: Expenditure, income, and production are intrinsically connected in a circular flow.
Multiplier Process in a Small Town: A single person's reduced spending ripples throughout the community, affecting the income and expenditure of others.
Practical Multiplier Effect: The multiplier, often smaller than theoretical calculations, is impacted by various factors in the real world.
