Social Studies: AP Macroeconomics: Fiscal Policy and Government Spending Worksheet

Question 1

An economy is in a recessionary gap. Identify one discretionary fiscal policy action the government could take to increase real GDP, and explain how it affects aggregate demand.

Accepted Answer

The government could increase government spending or decrease taxes. Either policy raises aggregate demand because government purchases directly add to spending or tax cuts increase disposable income and consumption.

Question 2

The marginal propensity to consume is 0.8. Calculate the government spending multiplier.

Accepted Answer

The government spending multiplier is 1 divided by 1 minus the MPC, so 1/(1 - 0.8) = 5. A $1 increase in government spending can increase aggregate demand by up to $5.

Question 3

The marginal propensity to consume is 0.75. The government increases spending by $40 billion. Calculate the maximum change in aggregate demand.

Accepted Answer

The spending multiplier is 1/(1 - 0.75) = 4. The maximum increase in aggregate demand is $40 billion times 4, which equals $160 billion.

Question 4

The marginal propensity to consume is 0.6. Calculate the tax multiplier and explain why it has a negative sign.

Accepted Answer

The tax multiplier is -MPC/(1 - MPC), so -0.6/(1 - 0.6) = -1.5. It is negative because a tax increase reduces disposable income, which lowers consumption and aggregate demand.

Question 5

An economy has a recessionary gap of $200 billion and an MPC of 0.75. Calculate the increase in government spending needed to close the gap.

Accepted Answer

The spending multiplier is 1/(1 - 0.75) = 4. The government spending increase needed is $200 billion divided by 4, which equals $50 billion.

Question 6

An economy has an inflationary gap. Explain how a decrease in government spending can help reduce inflationary pressure in the AD-AS model.

Accepted Answer

A decrease in government spending lowers aggregate demand and shifts the AD curve to the left. This reduces the price level and moves real GDP closer to potential output.

Question 7

Suppose the government cuts taxes by $100 billion and the MPC is 0.8. Calculate the maximum change in aggregate demand.

Accepted Answer

The tax multiplier is -0.8/(1 - 0.8) = -4. A tax cut is a negative change in taxes, so aggregate demand increases by $400 billion.

Question 8

Explain the difference between discretionary fiscal policy and automatic stabilizers. Give one example of each.

Accepted Answer

Discretionary fiscal policy requires deliberate government action, such as passing a new infrastructure spending bill. Automatic stabilizers change without new laws, such as unemployment benefits increasing during a recession.

Question 9

A government collects $3.8 trillion in tax revenue and spends $4.4 trillion in one year. Identify whether it has a budget deficit or surplus and calculate the amount.

Accepted Answer

The government has a budget deficit because spending is greater than tax revenue. The deficit is $4.4 trillion minus $3.8 trillion, which equals $0.6 trillion.

Question 10

Use the budget table to calculate the government's budget balance: tax revenue is $5.0 trillion, transfer payments are $1.5 trillion, government purchases are $3.0 trillion, and interest payments are $0.7 trillion.

Accepted Answer

Total spending is $1.5 trillion plus $3.0 trillion plus $0.7 trillion, which equals $5.2 trillion. The budget balance is $5.0 trillion minus $5.2 trillion, so the government has a $0.2 trillion deficit.

Question 11

Explain how persistent budget deficits can affect the national debt.

Accepted Answer

Persistent budget deficits increase the national debt because the government must borrow to pay for spending that exceeds revenue. Each year's deficit adds to the accumulated debt.

Question 12

Describe the crowding-out effect that can result from expansionary fiscal policy financed by borrowing.

Accepted Answer

Crowding out occurs when government borrowing increases demand for loanable funds, which raises real interest rates. Higher interest rates can reduce private investment and partially offset the increase in aggregate demand.

Question 13

A country is at full employment. The government increases spending without changing taxes. In the short run, predict the effect on real GDP, unemployment, and the price level.

Accepted Answer

In the short run, aggregate demand increases, so real GDP rises above potential output, unemployment falls below the natural rate, and the price level increases.

Question 14

Explain why a balanced budget increase in government spending and taxes can still increase aggregate demand.

Accepted Answer

A balanced budget increase can raise aggregate demand because the government spending multiplier is larger in absolute value than the tax multiplier. The direct increase in government purchases outweighs the decrease in consumption from higher taxes.

Question 15

A recession begins quickly, but Congress takes several months to approve a spending bill. Identify the type of fiscal policy lag shown and explain why it matters.

Accepted Answer

This is a decision lag because policymakers take time to agree on and approve a fiscal policy response. It matters because delayed action can make the policy less effective or cause it to take effect after economic conditions have changed.
