Multiplier Effect

The concept in economics where an initial increase in spending leads to a larger increase in national income and economic growth.

Formula for the Multiplier Effect

Multiplier = 1 / (1 - Marginal Propensity to Consume)

Marginal Propensity to Consume (MPC)

The proportion of additional income that individuals choose to spend on consumption rather than saving.

Marginal Propensity to Save (MPS)

The proportion of additional income that individuals choose to save rather than spend on consumption.

Factors Affecting the Multiplier Effect

The size of the marginal propensity to consume, leakages in the economy, and the presence of imports are factors that affect the multiplier effect.

Leakages

Savings, taxes, and imports are considered leakages as they reduce the amount of money circulating in the economy.

Injections

Investment, government spending, and exports are considered injections as they add money to the economy.

Examples of the Multiplier Effect

If the MPC is 0.8, an initial increase in government spending of $100 can lead to a total increase in national income of $500.

Limitations of the Multiplier Effect

The multiplier effect assumes constant MPC, ignores time lags, and does not account for changes in interest rates or inflation.
