To compute:
The value of change in aggregate
Answer to Problem 8P
The increase in value of aggregate demandis
The change in consumption will be $10 billion.
Explanation of Solution
Given information:
Government purchase is $20 billion.
Calculation for increase in aggregate demand:
Calculation for change in consumption:
Working note:
Calculation for Multiplier:
Marginal propensity to consume:
It refers to the aggregate increase in individual consumption due to increase in the income. It is calculated by dividing the change in consumption by the change in income. It is expressed as
Where
The value of MPC lies in between 0 to 1.
Aggregate expenditure:
It refers to the total amount of goods and services produced by an economy in a period. It is calculated by the sum of expenditures undertaken by the economy:
Here, C is consumption, I refer to investment, G represents government expenditure and NX is net export.
The increase in income is the multipliers times of the initial increase in purchase.
