REVIEW QUESTIONS

1. Which of the following would help a government reduce an inflationary output gap? LO1

a. Raising taxes.

b. Lowering taxes.

c. Increasing government spending.

d. Decreasing government spending.

Feedback: Raising taxes and decreasing government spending are the correct answers

because each of them helps to reduce aggregate demand. Consider raising taxes: When

2. The economy is in a recession. A congresswoman suggests increasing spending to stimulate

aggregate demand but also at the same time raising taxes to pay for the increased spending. Her

suggestion to combine higher government expenditures with higher taxes is: LO1

a. The worst possible combination of tax and expenditure changes.

b. The best possible combination of tax and expenditure changes.

c. A mediocre and contradictory combination of tax and expenditure changes.

d. None of the above.

Feedback: The Congresswoman’s suggestion to increase spending but at the same time

The problem is that the two policies contradict each other. This is true because increasing

b. No.

Feedback: The U.S. tax system does appear to have built-in stabilizers. In particular, it

appears to have a tax system that collects more money when the economy is doing well

4. Last year, while an economy was in a recession, government spending was $595 billion and

government revenue was $505 billion. Economists estimate that if the economy had been at its

full-employment level of GDP last year, government spending would have been $555 billion and

government revenue would have been $550 billion. Which of the following statements about this

government’s fiscal situation are true? LO3

a. The government has a non–cyclically adjusted budget deficit of $595 billion.

b. The government has a non–cyclically adjusted budget deficit of $90 billion.

c. The government has a non–cyclically adjusted budget surplus of $90 billion.

d. The government has a cyclically adjusted budget deficit of $555 billion.

e. The government has a cyclically adjusted budget deficit of $5 billion.

f. The government has a cyclically adjusted budget surplus of $5 billion.

Answer: c. The government has a non-cyclically adjusted budget deficit of $90 billion; e.

Feedback: The two correct answers are that the government has a non-cyclically

5. Label each of the following scenarios in which there are problems enacting and applying fiscal

policy as being an example of either recognition lag, administrative lag, or operational lag. LO5

a. To fight a recession, Congress has passed a bill to increase infrastructure spending—but the

legally required environmental-impact statement for each new project will take at least two years

to complete before any building can begin.

b. Distracted by a war that is going badly, inflation reaches 8 percent before politicians take

notice.

c. A sudden recession is recognized by politicians, but it takes many months of political deal

making before a stimulus bill is finally approved.

d. To fight a recession, the president orders federal agencies to get rid of petty regulations that

burden private businesses—but the federal agencies begin by spending a year developing a set of

regulations on how to remove petty regulations.

Answers: a. Operational lag: The two-year long process to complete environmental-

impact statements is an example of an operational lag because even after the stimulus

and a policy decision is reached. d. Operational lag: The delay caused by the bureaucrats

6. In January, the interest rate is 5 percent and firms borrow $50 billion per month for investment

projects. In February, the federal government doubles its monthly borrowing from $25 billion to

$50 billion. That drives the interest rate up to 7 percent. As a result, firms cut back their

borrowing to only $30 billion per month. Which of the following is true? LO6

a. There is no crowding-out effect because the government’s increase in borrowing exceeds firm’s

decrease in borrowing.

b. There is a crowding-out effect of $20 billion.

c. There is no crowding-out effect because both the government and firms are still borrowing a

lot.

d. There is a crowding-out effect of $25 billion.

Feedback: There is a crowding-out effect of $20 billion: A crowding-out effect occurs

when increased government borrowing drives up interest rates and thereby reduces

investment by firms. That is precisely what happens in this scenario, where the

PROBLEMS

1. Assume that a hypothetical economy with an MPC of .8 is experiencing severe recession. By

how much would government spending have to rise to shift the aggregate demand curve

rightward by $25 billion? How large a tax cut would be needed to achieve the same increase in

aggregate demand? Determine one possible combination of government spending increases and

tax increases that would accomplish the same goal without changing the amount of outstanding

debt. LO1

Feedback: Part 1: The first step is to find the expenditure multiplier.

relationship.

Δ AD = expenditure multiplier x Δ government spending

rearranging,

Δ government spending = Δ AD/expenditure multiplier

Part 2: The first step is to calculate the tax multiplier. Here we need to recognize that a

tax cut will need to move through consumption before impacting the economy. Therefore

we need to multiply the tax cut by the MPC before applying the multiplier process.

Note that the tax multiplier is negative because changes in taxes and aggregate demand

(and aggregate expenditures) are inversely related.

The second step is to find the change in taxes required to shift the aggregate demand

schedule rightward by $25 billion. Here we use the following relationship.

Δ AD = tax multiplier x Δ taxes

rearranging,

Δ taxes = Δ AD/tax multiplier

Part 3: To answer this question we want to use the balanced budget multiplier concept.

First, we increase government spending by $25 billion. This results in an increase in

2. Refer back to the table in Figure 30.7 in the previous chapter. Suppose that aggregate demand

increases such that the amount of real output demanded rises by $7 billion at each price level. By

what percent will the price level increase? Will this inflation be demand-pull inflation or will it be

cost-push inflation? If potential real GDP (that is, full-employment GDP) is $510 billion, what

will be the size of the positive GDP gap after the change in aggregate demand? If government

wants to use fiscal policy to counter the resulting inflation without changing tax rates, would it

increase government spending or decrease it? LO1

Answers: increase by 8 percent; demand-pull inflation; $3 billion; decrease government

spending.

After the increase in real output demanded by $7 billion at each price level we see that

the new equilibrium is $513 billion (quantity demanded equals quantity supplied) at the

Since this inflation is the result of an increase in aggregate demand this is demand-pull

If government wants to use fiscal policy to counter this inflation without changing tax

rates, it would decrease government spending.

3. (For students who were assigned Chapter 29) Assume that, without taxes, the consumption

schedule for an economy is as shown below: LO1

a. Graph this consumption schedule. What is the size of the MPC?

b. Assume that a lump-sum (regressive) tax of $10 billion is imposed at all levels of GDP.

Calculate the tax rate at each level of GDP. Graph the resulting consumption schedule and

compare the MPC and the multiplier with those of the pretax consumption schedule.

c. Now suppose a proportional tax with a 10 percent tax rate is imposed instead of the regressive

tax. Calculate and graph the new consumption schedule and note the MPC (tax inclusive) and the

multiplier.

d. Finally, impose a progressive tax such that the tax rate is 0 percent when GDP is $100, 5

percent at $200, 10 percent at $300, 15 percent at $400, and so forth. Determine and graph the

new consumption schedule, noting the effect of this tax system on the MPC (tax inclusive) and

the multiplier.

e. Use a graph similar to Figure 30.3 to show why proportional and progressive taxes contribute

to greater economic stability, while a regressive tax does not.

7. Suppose that the investment demand curve in a certain economy is such that investment

declines by $100 billion for every 1 percentage point increase in the real interest rate. Also,

suppose that the investment demand curve shifts rightward by $150 billion at each real interest

rate for every 1 percentage point increase in the expected rate of return from investment. If

stimulus spending (an expansionary fiscal policy) by government increases the real interest rate

by 2 percentage points, but also raises the expected rate of return on investment by 1 percentage

point, how much investment, if any, will be crowded out? LO6

Feedback: If stimulus spending (an expansionary fiscal policy) by government increases

the real interest rate by 2 percentage points this will reduce investment by $200 billion.
