According to Keynesian theory, the correct fiscal policy to stimulate the economy would be to:
increase government expenditures to increase aggregate demand.
According to Keynes, unemployment resulted from:
Insufficient spending on the part of consumers, business, and government.
In Figure 8.5, according to Keynesians, if equilibrium real output is Q1 and full employment real output is Q2, an appropriate fiscal policy lever would be to:
Increase AD by increasing government spending.
In Figure 8.5, if equilibrium real output is Q1 and full employment real output is Q2, an appropriate monetarist policy lever would be to increase:
AD by reducing interest rates.
The components of aggregate demand are:
Consumption, government spending, net exports, and investment.
If disposable income increases from $9,000 billion to $11,000 billion, and consumption increases from $9,500 billion to $11,000 billion, the MPC must be:
0.75. The MPC is equal to the change in consumption spending divided by the change in disposable income. (1500/2000 = .75)
Suppose the consumption function is C = $200 + 0.85YD. If disposable income is $400, consumption is:
$540. The level of consumption is equal to autonomous consumption plus the disposable income multiplied by the MPC; .85×400 + 200 = 540.
Which of the following is true when an economy produces at full employment, but consumers, government, businesses, and the foreign sector do not buy all the output?
There is a recessionary gap
The economy will not reach and maintain its goals of full employment and price stability if aggregate demand is too:
Great, too small or unstable
Using Figure 9.6, if full employment occurs at QC then aggregate demand is:
Too small causing cyclical unemployment.
If an economy is at full employment and investment spending decreases while all other levels of spending remaining constant then the price level:
Decreases and output decreases.
If an economy is at full employment and consumption spending decreases while all other levels of spending remaining constant then:
Increased unemployment results.
The marginal propensity to consume is:
The fraction of each additional dollar of disposable income spent on consumption.
Suppose an economy can be described by the consumption function C = 250 + 0.90YD and I = $300. What is the multiplier?
10. The multiplier is equal to 1 ÷ (1 - MPC), and MPC is the slope variable.
If the MPC = 0.80, the cumulative decrease in total spending resulting from an initial $150 recessionary gap would be:
$750. One can determine the total change in spending by taking the initial change in spending and multiplying it by the multiplier, where the multiplier is equal to 1 ÷ (1 - MPC).
If leakages are greater than injections, then equilibrium output will be:
Less than full-employment output and a recessionary gap will occur.
Assume the equilibrium level of output is less than full employment. To achieve a full-employment equilibrium the aggregate demand curve must shift to the right by:
An amount greater than the recessionary GDP gap because the spending increase raises the price level.
When an economy is operating at "full employment," as economists usually define the term:
The unemployment rate is between 4-6 percent.
To eliminate an AD shortfall of $100 billion when the economy has an MPC of 0.50, the government should increase spending by:
$50 billion. The general formula for computing the desired stimulus (increase in government spending) is the AD shortfall divided by the multiplier, therefore $100 billion divided by 2 (1/(1 - .5) is equal to $50 billion.
Given a $500 billion AD shortfall and an MPC of 0.75, the desired fiscal stimulus would be:
A $125 billion increase in government expenditures. The general formula for computing the desired stimulus (increase in government spending) is the AD shortfall divided by the multiplier, therefore $500 billion divided by 4 (1/(1 - .75)) is equal to $125 billion.
Assume the MPC is 0.80. If the government wants to eliminate an AD shortfall of $300 billion it should:
Cut taxes by $75 billion. The general formula for computing the desired stimulus is the AD shortfall divided by the multiplier (300/5 = 60) and the formula to determine the tax cut necessary to close a GDP gap is the desired fiscal stimulus divided by the MPC (60/.8 = 75). Therefore the tax cut necessary to close a $300 AD shortfall (when the MPC is 0.80) is $75 billion.
f the government cuts taxes by $200 million and simultaneously decreases government spending by $200 million, then:
People will spend only a part of their tax cut, so aggregate demand will eventually fall by $200 million.
Using Figure 11.1, which fiscal policy action would increase aggregate demand from AD1 to AD3?
A decrease in taxes
