Assume that total expenditure E comprises the sum of government consumption, G, household consumption, C, and investment, I. Assume a closed macroeconomic system, so that income equals expenditure Y=E. If we define household saving, SH, as SH=Y-T-C, where the cunsumption function is a fixed proportion of disposable income, C=c(Y-T), which of the following will be true?
a. Higher government spending alongside unchanged taxation will lead to higher investment and higher household saving
b. Higher government spending alongside unchanged taxation will have no effect on household saving or investment
c. Higher government spending alongside unchanged taxation will lead to higher household saving
d. Higher government spending alongside unchanged taxation will lead to lower household saving
Equilibrium in the goods market requires that Aggregate Output equals Aggregate Expenditures. Given that Consumption = Disposable Income minus Private Savings, mathematically prove that equilibrium in the goods market requires Investment (I) to equal national savings (S) -- hence the IS curve.
In a closed economy, subsistence consumption is 10 billions, households spend 60% of their net disposable income on leisure consumption, investment is constant at 40 billions, taxes are 20 billions, government spending is 20 billions and the gross domestic product is 145 billions. Assume that suppliers always respond to variations in demand, that it takes them 1 month to adjust to new demand levels and that they make adjustments once per month (if any). One day, the government increases its spending to 30 billions.
After 2 months (at the end of the 2nd month), by how much has the gross domestic product increased?
Select one:
a. 16
b. 25.
c. 32
d. 50

- Refer to the accompanying figures, with consumption schedules in figure (A) and saving schedules in figure (B), which correspond to each other across different levels of disposable income. If, in figure (A), consumption shifts from A2 to A3 because of a change in taxes, then in figure (B) line B2 will shift to B3. B1 will shift to B2. B2 will shift to B1. B3 will shift to B2.arrow_forwardWhat does it mean by the logic: When output is too low, what needed is an increase in demand for goods and services. Investment is one component of demand, and saving equals investment. Therefore, if the government could just convince households to attempt to save more, then investment and output would increase.arrow_forwardConsider a closed economy without a government.
