Question 1

1. Increase government purchases to shift AD right, though the price level may rise more than expected in the short run.
2. Decrease taxes to shift AD right, though real GDP may rise by less than expected in the short run.
3. Decrease government spending to shift AD left, though real GDP may fall by less than expected in the short run. (correct answer)
4. Increase the money supply to shift AD left, though inflation may rise by less than expected in the short run.
5. Wait for wages to adjust so SRAS shifts right, though inflation may rise by less than expected in the short run.

Explanation: Short-run stabilization aims to adjust aggregate demand to align with potential output, but uncertainties like multipliers can lead to partial effects. For an inflationary gap with accelerating inflation and output above potential, decreasing government spending shifts AD left, reducing real GDP though possibly by less than anticipated due to implementation delays or weaker multipliers. This policy acknowledges the gap's excess demand, targeting a moderated contraction while recognizing real-world limitations. A misconception is that waiting for SRAS shifts (choice E) is fiscal policy, but it's a passive long-run adjustment, not a short-run discretionary action. The strategy involves identifying the inflationary gap and selecting opposite-direction fiscal policy—contractionary—to temper demand, mindful of potential incomplete outcomes.

Question 2

1. Real GDP rises toward $Y^*$ and unemployment falls, with upward pressure on the price level. (correct answer)
2. Real GDP falls farther below $Y^*$ and unemployment rises, with downward pressure on the price level.
3. Real GDP returns to $Y^*$ only because nominal wages immediately fall across the economy.
4. Real GDP rises toward $Y^*$ because the central bank increases the money supply automatically.
5. Real GDP is unchanged because fiscal policy affects only long-run potential output.

Explanation: Short-run stabilization employs fiscal measures to close output gaps swiftly, avoiding deep recessions or excessive inflation through demand adjustments. In a recessionary gap with GDP at $14.4 trillion below $15.0 trillion potential, expansionary fiscal policy like increased government purchases raises aggregate demand, moving GDP toward potential and reducing unemployment with some price pressure. The stimulus highlights this partial effectiveness without perfect closure. A misconception is that fiscal policy only affects long-run potential (option E), but it primarily influences short-run demand. Transferable strategy: spot the recessionary gap and apply expansionary fiscal policy to shift demand right. This promotes recovery while acknowledging incomplete adjustments due to multipliers.

Question 3

1. Increase government purchases to shift aggregate demand right in the short run.
2. Decrease personal income taxes to raise disposable income in the short run.
3. Decrease government purchases to shift aggregate demand left in the short run. (correct answer)
4. Rely on long-run self-adjustment as wages rise and SRAS shifts right automatically.
5. Lower the policy interest rate to increase consumption and investment spending.

Explanation: Short-run stabilization involves using fiscal tools to adjust aggregate demand and bring the economy back to potential output, minimizing inflationary pressures or unemployment spikes. For an inflationary gap with real GDP at 10,600 above the 10,000 potential and inflation rising to 6%, decreasing government purchases shifts aggregate demand left, cooling the economy and stabilizing prices. This policy matches the stimulus by countering the overheating without immediate monetary intervention, though delays may occur. One misconception is that lowering interest rates (option E) is fiscal policy, but it's actually monetary policy. The transferable strategy: diagnose the inflationary gap and select contractionary fiscal actions to shift demand left. Such measures help restore equilibrium without waiting for long-run adjustments like wage increases.

Question 4

1. Recognition and implementation lags can delay the effect of discretionary fiscal policy in the short run. (correct answer)
2. Discretionary fiscal policy affects output instantly because prices are fixed in the short run.
3. Lags are irrelevant because automatic stabilizers require new legislation to operate.
4. Policy lags imply aggregate demand will shift left when government spending increases.
5. Policy lags imply the economy will return to potential immediately without any AD change.

Explanation: Policy lags are crucial limitations of discretionary fiscal policy that can reduce its effectiveness for short-run stabilization. Recognition lag occurs when policymakers take time to identify the problem, while implementation lag happens between policy approval and actual spending changes—the scenario mentions several months before the bill takes effect. These lags mean the economy might already be recovering (or worsening) by the time fiscal policy impacts aggregate demand. Unlike automatic stabilizers that respond immediately, discretionary actions face timing challenges. The key insight is that lags don't change the direction of policy effects but can make them arrive too late to be optimally effective.

Question 5

1. Aggregate demand increases, raising real output and employment toward potential. (correct answer)
2. Aggregate demand decreases, lowering real output and employment further below potential.
3. Short-run aggregate supply increases immediately, raising output without any demand change.
4. Long-run aggregate supply shifts left, raising the price level and closing the gap.
5. The money supply increases automatically, shifting aggregate demand right without fiscal policy.

Explanation: Short-run fiscal stabilization through tax cuts works by increasing disposable income, which raises consumption and aggregate demand. When the government cuts personal income taxes during a recession, households keep more of their earnings, typically spending a portion (based on marginal propensity to consume) and saving the rest. This increased consumption shifts aggregate demand rightward, raising real output and employment toward potential. The stimulus shows a significant recessionary gap ($0.4T) where expansionary policy is appropriate. A common misconception is thinking tax cuts reduce demand (choice B), but they increase household purchasing power. The transferable strategy: tax cuts → higher disposable income → increased consumption → rightward AD shift → higher output/employment.

Question 6

1. Increase transfer payments and cut taxes to expand aggregate demand.
2. Decrease government purchases and increase taxes to contract aggregate demand. (correct answer)
3. Do nothing because aggregate demand cannot be affected by fiscal policy in the short run.
4. Buy government bonds to increase the money supply and reduce aggregate demand.
5. Increase government purchases to shift aggregate demand left through a multiplier.

Explanation: Short-run fiscal stabilization requires matching policy direction to the output gap—contractionary for inflation, expansionary for recession. With actual GDP ($26.0T) exceeding potential ($25.0T) by $1T and unemployment at just 3%, the economy faces substantial inflationary pressure from excess demand. Appropriate contractionary fiscal policy combines spending cuts and tax increases to withdraw purchasing power from the overheated economy, shifting aggregate demand leftward. The stimulus confirms strong demand requiring cooling despite automatic stabilizers already helping. A common misconception is prescribing expansionary policy (choice A) for any problem, but that would worsen inflation. The transferable strategy: inflationary gap → contractionary fiscal mix (cut G, raise T) → reduced AD → output falls toward potential.

Question 7

1. Automatic stabilizer: an increase in unemployment insurance payments; Discretionary action: a new temporary increase in government purchases. (correct answer)
2. Automatic stabilizer: a new infrastructure bill passed by Congress; Discretionary action: lower tax revenue due to falling incomes.
3. Automatic stabilizer: a central bank open-market purchase; Discretionary action: a reduction in reserve requirements.
4. Automatic stabilizer: a legislated increase in the corporate tax rate; Discretionary action: higher transfer payments due to recession.
5. Automatic stabilizer: waiting for nominal wages to fall; Discretionary action: waiting for SRAS to shift right.

Explanation: Short-run stabilization policies help smooth economic cycles by influencing aggregate demand, with automatic stabilizers activating without new laws and discretionary actions requiring deliberate decisions. In a recessionary gap ($9.5 trillion vs. $10.0 trillion), an automatic stabilizer like increased unemployment insurance payments boosts AD by supporting household spending, while a discretionary action, such as a new increase in government purchases, actively shifts AD right through legislative choice. This distinction is clear in the scenario, where the gap signals weak demand that automatic features partially offset, but discretionary steps provide targeted stimulus. A misconception is viewing new legislation like an infrastructure bill as automatic (choice B), when it actually requires congressional approval, making it discretionary. The transferable approach is to identify the recessionary gap and select opposite-direction fiscal policy—expansionary—while distinguishing built-in stabilizers from intentional interventions.

Question 8

1. Increase government purchases or cut taxes to shift AD right.
2. Decrease government purchases or increase taxes to shift AD left. (correct answer)
3. Wait for SRAS to shift left until output returns to potential in the long run.
4. Buy government bonds to increase the money supply and shift AD left.
5. Cut taxes to reduce aggregate demand through lower disposable income.

Explanation: Short-run fiscal stabilization aims to close output gaps by shifting aggregate demand through government spending or tax changes. With actual GDP ($18.7T) exceeding potential ($18.0T), the economy experiences an inflationary gap with low unemployment (3.4%) and high inflation (5.6%). Contractionary fiscal policy is appropriate here—decreasing government purchases or raising taxes shifts AD leftward, reducing output back toward potential and easing price pressures. The data confirms overheating: unemployment is below natural rates while inflation exceeds typical targets. A key misconception is confusing fiscal tools (G and T) with monetary tools (bond operations affect money supply, not fiscal policy). The strategy remains consistent: identify gap direction (inflationary = above potential), then apply opposite fiscal policy (contractionary = decrease G or raise taxes).

Question 9

1. Unemployment insurance payments rise as more workers qualify, supporting consumption. (correct answer)
2. Congress passes a permanent cut in corporate tax rates to raise long-run growth.
3. The central bank buys bonds to lower interest rates and raise investment spending.
4. The government reduces transfer payments to shrink the budget deficit in the short run.
5. Firms cut nominal wages immediately, shifting SRAS right to restore full employment.

Explanation: Automatic stabilizers are fiscal mechanisms that adjust without new legislation, helping to moderate business cycles. During a recessionary gap (actual $21.3T < potential $22.0T with 7.2% unemployment), unemployment insurance payments automatically increase as more workers qualify for benefits. This maintains household consumption spending, preventing AD from falling further and providing counter-cyclical support. The stimulus shows high unemployment triggering these automatic transfers. A key misconception is confusing automatic stabilizers with discretionary actions—Congress passing new laws (option B) or central bank operations (option C) require active decisions. The transferable principle: automatic stabilizers work opposite to the cycle—in recessions, transfers rise and tax collections fall, both supporting AD without legislative action.

Question 10

1. Decrease government purchases or increase taxes to shift AD left.
2. Increase government purchases to shift AD right toward potential output. (correct answer)
3. Wait for wages and prices to fall until output returns to potential in the long run.
4. Sell government bonds to raise the money supply and shift AD right.
5. Increase taxes to reduce consumption, shifting AD right as prices fall.

Explanation: Short-run fiscal stabilization involves using government spending or taxes to shift aggregate demand (AD) and close output gaps. With actual GDP ($19.2T) below potential ($20.0T), the economy faces a recessionary gap characterized by high unemployment (6.8%) and low inflation (1.1%). To address this gap, expansionary fiscal policy is needed—specifically, increasing government purchases shifts AD rightward, raising output toward potential. The stimulus data confirms the need for expansion: unemployment exceeds natural rates and inflation is below target. A common misconception is that selling bonds is fiscal policy (it's actually monetary policy conducted by the central bank). The transferable strategy is: identify the gap direction (recession = below potential), then apply opposite-direction fiscal policy (expansionary = increase G or cut taxes).

Question 11

1. Passing a new temporary payroll tax cut is discretionary; higher unemployment benefits are automatic. (correct answer)
2. Higher unemployment benefits are discretionary; passing a new tax law is automatic.
3. Both a new tax law and higher unemployment benefits occur automatically without legislation.
4. Neither tax changes nor transfer payments affect AD in the short run; only SRAS changes matter.
5. A new temporary payroll tax cut is monetary policy; higher unemployment benefits are fiscal policy.

Explanation: Understanding fiscal policy requires distinguishing discretionary actions from automatic stabilizers. A temporary payroll tax cut requires new legislation—Congress must actively pass a law, making it discretionary fiscal policy aimed at increasing disposable income during the recession. In contrast, unemployment benefits rise automatically when joblessness increases, requiring no new legislative action. The recessionary gap context (actual $13.4T < potential $14.0T) triggers both responses, but only one is automatic. A key misconception is thinking all fiscal changes require legislation—automatic stabilizers are pre-existing programs that adjust with economic conditions. The transferable distinction: discretionary = new laws needed; automatic = existing programs respond to economic indicators without legislative action.

Question 12

1. Discretionary fiscal policy can be delayed by recognition and legislative lags, so it may take time to affect AD in the short run. (correct answer)
2. Discretionary fiscal policy has no inside lag because Congress can change spending and taxes instantly.
3. Discretionary fiscal policy affects real GDP only after LRAS shifts, so it cannot influence the short run.
4. Discretionary fiscal policy works only if the central bank simultaneously increases the money supply.
5. Discretionary fiscal policy shifts SRAS rather than AD, so timing lags are not relevant to output changes.

Explanation: Short-run stabilization uses fiscal measures to adjust aggregate demand promptly, but timing issues can limit effectiveness. In an inflationary gap with rising prices and output above potential, contractionary fiscal policy aims to shift AD left, yet recognition lags (identifying the problem) and legislative lags (passing laws) delay implementation, potentially missing the short-run window. This limitation is evident in the scenario, where accelerating inflation calls for quick action, but delays mean the policy might affect AD too late or during recovery. A common misconception is that fiscal policy has no inside lags and acts instantly (choice B), ignoring real-world political processes. The strategy is to recognize the inflationary gap and choose opposite-direction fiscal policy—contractionary—while accounting for lags that may reduce its short-run impact.

Question 13

1. Income tax revenues rise as incomes increase, reducing disposable income in the short run. (correct answer)
2. Congress enacts a new across-the-board tax cut, raising disposable income in the short run.
3. The central bank sells government bonds, lowering aggregate demand in the short run.
4. The government increases transfer payments by passing a new benefits bill.
5. Nominal wages rise immediately, shifting long-run aggregate supply right in the short run.

Explanation: Automatic stabilizers work without new legislation to partially offset economic fluctuations. During an inflationary gap when Real GDP exceeds potential and incomes are rising quickly, progressive income taxes automatically collect more revenue as people move into higher tax brackets. This reduces disposable income and dampens aggregate demand without any policy action. The scenario explicitly states no new legislation has been passed, confirming we need an automatic response. The key insight is that automatic stabilizers work in both directions—they expand during recessions and contract during booms to provide counter-cyclical stabilization.

Question 14

1. Increase personal income tax rates to reduce consumption spending in the short run. (correct answer)
2. Decrease personal income tax rates to increase consumption spending in the short run.
3. Increase government purchases to raise aggregate demand in the short run.
4. Wait for wages to rise so SRAS shifts left and closes the gap in the long run.
5. Increase the money supply to lower interest rates and raise investment spending.

Explanation: Short-run stabilization uses fiscal policies to manage demand and close gaps, distinguishing from monetary or long-run adjustments. For an inflationary gap with GDP at $6.4 trillion above $6.0 trillion potential and rising inflation expectations, increasing income tax rates is contractionary fiscal, reducing consumption. The stimulus highlights this without monetary involvement. A misconception is that decreasing taxes is contractionary (option B), but it expands demand. Transferable strategy: diagnose the inflationary gap and choose contractionary fiscal policy to shift demand left. This curbs overheating effectively in the short run.

Question 15

1. Discretionary fiscal policy can face recognition and implementation lags that delay its short-run impact. (correct answer)
2. Discretionary fiscal policy has no lags because Congress can adjust taxes continuously each day.
3. Automatic stabilizers have longer lags than discretionary policy because they require new legislation.
4. Fiscal policy works only after the economy self-adjusts back to $Y^*$ in the long run.
5. Fiscal policy timing is irrelevant because aggregate demand is fixed in the short run.

Explanation: Short-run stabilization utilizes fiscal policies to mitigate gaps, but discretionary actions often face lags in recognition and implementation, delaying effects. In this recessionary gap with GDP at $11.6 trillion below $12.0 trillion potential, a proposed tax cut next quarter illustrates these timing issues. The stimulus notes legislative approval adds to delays. A misconception is that discretionary policy has no lags due to continuous adjustments (option B), overlooking real-world processes. Transferable strategy: diagnose the gap and choose opposite fiscal policy—expansionary for recessionary—while accounting for lags. This enhances policy effectiveness despite timing challenges.

Question 16

1. Congress passes a temporary increase in infrastructure spending this quarter.
2. The central bank lowers the policy interest rate to stimulate investment.
3. Unemployment insurance payments rise as more workers become eligible. (correct answer)
4. The government raises marginal income tax rates to reduce inflation.
5. Firms cut nominal wages, shifting short-run aggregate supply right over time.

Explanation: Automatic stabilizers are built-in fiscal mechanisms that respond to economic changes without new legislation, unlike discretionary actions that require policy decisions. During a recession, unemployment insurance payments automatically increase as more workers lose jobs and become eligible for benefits. This increases transfer payments, which raises disposable income and aggregate demand without Congress passing any new laws. The stimulus confirms we're in a recession (Real GDP below potential), making unemployment benefits the classic automatic stabilizer. A common misconception is confusing automatic stabilizers with discretionary actions—remember that automatic means no new policy decision is needed.

Question 17

1. Lower tax revenue caused by falling incomes under a progressive tax system.
2. Higher unemployment insurance payments triggered by rising unemployment.
3. A newly passed temporary increase in government purchases for public works projects. (correct answer)
4. A decrease in tax collections caused by a smaller tax base during the downturn.
5. An increase in transfer payments that occurs automatically as eligibility rises.

Explanation: Short-run stabilization includes automatic stabilizers that buffer gaps without new laws and discretionary policies that require active intervention. In a recessionary gap with GDP at $2.8 trillion below $3.0 trillion potential and falling tax revenue, a newly passed increase in government purchases is discretionary expansionary policy. The stimulus contrasts this with automatic elements like declining taxes. A misconception is that automatic stabilizers include all transfer increases (option E), but discretionary ones need legislation. Transferable strategy: identify the recessionary gap and apply expansionary fiscal policy, distinguishing discretionary from automatic. This approach supports timely demand boosts.

Question 18

1. Automatic stabilizers require new legislation, while discretionary policy occurs without any policy change.
2. Automatic stabilizers reduce aggregate demand as taxes rise with income, while discretionary policy requires legislative action. (correct answer)
3. Automatic stabilizers increase aggregate demand in booms, while discretionary policy reduces it in recessions.
4. Automatic stabilizers work only through government purchases, while discretionary policy works only through transfer payments.
5. Automatic stabilizers operate by changing the money supply, while discretionary policy changes interest rates.

Explanation: Short-run fiscal stabilization operates through two channels: automatic stabilizers and discretionary policy, distinguished by whether legislative action is required. Automatic stabilizers work without new laws—as the economy booms and incomes rise, tax revenues automatically increase (reducing disposable income and aggregate demand), while discretionary policy requires Congress to actively change tax rates or spending levels. During the inflationary gap shown, rising incomes trigger higher tax collections that partially cool demand without legislation. A common misconception is reversing these definitions (choice A), but automatic means no action needed. The transferable strategy: automatic = built-in response (taxes rise with income), discretionary = deliberate legislative change (Congress votes).

Question 19

1. Congress passes a one-time infrastructure spending bill targeted at highways.
2. The central bank lowers the policy interest rate to stimulate private spending.
3. Unemployment insurance payments rise as more workers become eligible. (correct answer)
4. The government raises income tax rates to balance the budget during the downturn.
5. Firms cut nominal wages immediately, raising real output back to potential.

Explanation: Short-run stabilization includes both discretionary actions and automatic stabilizers—built-in features that adjust without new legislation. During recessions, unemployment insurance payments automatically rise as more workers qualify, injecting spending into the economy without Congressional action. This differs from discretionary policies like infrastructure bills (choice A) that require legislative approval. The stimulus shows rising unemployment (5% to 7%), triggering higher transfer payments that partially offset falling private demand. A common misconception is thinking automatic stabilizers need new laws, but they're pre-existing programs that expand/contract with economic conditions. The transferable strategy: automatic stabilizers work through existing programs (unemployment insurance, progressive taxes) that counteract cycles without policy delays.

Question 20

1. Aggregate demand decreases, and real output moves toward potential from above. (correct answer)
2. Aggregate demand increases, and real output rises further above potential.
3. Aggregate demand decreases, and real output moves further above potential.
4. Aggregate demand increases, and real output falls toward potential from above.
5. Aggregate demand does not change, and real output returns to potential due to instant wage adjustment.

Explanation: Short-run fiscal stabilization works by shifting aggregate demand to close output gaps. When government purchases decrease during an inflationary gap, this directly reduces a component of aggregate demand (C + I + G + NX), shifting the AD curve leftward. With actual output ($12.4T) above potential ($12.0T), this contractionary action helps cool the overheated economy by reducing total spending, moving real output back toward potential from above. The stimulus confirms excess demand requiring contraction. A common misconception is thinking reduced government spending somehow increases demand (choice B), but G is a direct component of AD. The transferable strategy: trace fiscal actions through AD components—cutting G directly reduces aggregate demand, appropriate for inflationary gaps.
