If the economy is at both short-run and long-run macroeconomic equilibrium, then

If the inflationary gap is $50 billion and the multiplier is 4, what is the reduction in aggregate spending needed to reach full employment?
$50 billion
In a simple aggregate expenditures model with no government and no international trade, if savings is $2 trillion and consumer spending is $6 trillion, what are aggregate expenditures?
$8 trillion
What is Alice's marginal propensity to consume if she increases her spending by $1,000 after she receives a $5,000 raise in salary?
0.2 Alice's marginal propensity to consume is 0.2. It is determined by dividing the change in consumption by the change in income. The equation is: MPC = $1,000/$5,000 = 0.2.
What is the spending multiplier if the marginal propensity to consume is 0.2?
1.25 The spending multiplier is is determined by dividing 1 by (1 − MPC). The equation is multiplier = 1/(1 − 0.2) = 1/0.8 = 1.25.
The multiplier is calculated as
1/(1 - MPC)
If the marginal propensity to save is 0.5, what is the multiplier?
2
How much will $200 in new spending change equilibrium income if the marginal propensity to save is 0.2?
$1,000 This is determined by multiplying the amount of new spending by the multiplier, which is 1/(1 − MPC) = 1/MPS = 1/(0.2) = 5; 5 × $200 = $1,000.
What is the savings amount if disposable income is $50,000 and consumption is $32,000?
$18,000 Savings is equal to $18,000. Savings equals the difference between income and consumption. The equation is savings = $50,000 − $32,000 = $18,000.
According to the full aggregate expenditures model, if investment is $4 trillion, government spending is $2 trillion, exports are $1 trillion, taxes are $2 trillion, and imports are $3 trillion, what is savings?
$2 trillion
The _____ is the change in consumption associated with a given change in income.
marginal propensity to consume
If the multiplier is 7 and new spending is $50, by how much will spending increase?
$350 The increase in spending will increase by $350. It is determined by multiplying the multiplier by the amount of new spending. $50 × 7 = $350
According to the full aggregate expenditures model, if investment is $5 trillion, government spending is $2 trillion, savings is $4 trillion, and net exports are $1 trillion, what are taxes?
$4 trillion The sum of investment, government spending, and exports must equal the sum of savings, taxes, and imports. Since the sum of government spending, investment, and exports is at least $8 trillion, taxes must be $4 trillion.
Because many input costs are sticky in the short run, the short-run aggregate supply curve is
positively sloped.
If the spending multiplier is 5, then the marginal propensity to _____ is 0.2.
save
According to the full aggregate expenditures model, if investment is $1 trillion, government spending is $4 trillion, taxes are $4 trillion, and net exports are $0, what is savings?
$1 trillion
The aggregate demand curve is downward-sloping due to the
effect of prices on the demand for money.
If the multiplier is 5 and new spending is $100, by how much will spending increase?
$500 Spending is determined by multiplying the multiplier by the amount of new spending: $100 × 5 = $500.
If the marginal propensity to consume is 0.5; taxes are increased by $500,000; and government spending is increased by $500,000, what is the change in income?
$500,000 The change in income will be $500,000 because according to the balanced budget multiplier, equal changes in government spending and taxation lead to an equal change in income.
How much will $200 in new spending change equilibrium income if the marginal propensity to consume is 0.2?
$250 This is determined by multiplying the amount of new spending by the multiplier, which is 1/(1 − MPC), or 1/MPS = 1/(1 − 0.2) = 1.25; 1.25 × $200 = $250.
According to the full aggregate expenditures model, if business investment is $2 trillion, savings is $4 trillion, and taxes are $3 trillion, how much is government spending in a closed economy?
$5 trillion If the sum of taxes and savings is $7 trillion, then that must mean that the summation of government spending and business investment is also $7 trillion; 2 + 5 = 7.
Because Susom received a raise in pay from $30,000 to $50,000, his consumption increased from $29,000 to $45,000. What is Susom's marginal propensity to save?
0.2
Because Mayara received a raise in pay from $90,000 to $100,000, her consumption increased from $50,000 to $55,000. What is Mayara's marginal propensity to consume?
0.5 Mayara's marginal propensity to consume is determined by dividing the change in consumption by the change in income. The equation is MPC = δ C/ δY = ($55,000 − $50,000)/($100,000 − $90,000) = $5,000/$10,000 = 0.5.
If Belinda's marginal propensity to save is 0.2, what is her marginal propensity to consume?
0.8
What is the average propensity to consume if income is $50,000 and savings is $10,000?
0.8
